Delta Membrane Systems - Delta's Fresh FLORAXX
Two design options are offered by Delta Membrane Systems in the new Delta-FLORAXX range, bringing innovative drainage solutions in green roofing applications.

Delta-FLORAXX is used on inverted roofs to drain water away from insulation panels under accessible surfaces. Thanks to its breathable perforation and its dimples, water and air may circulate freely on the underside so that no coherent film of water can form on the insulation.

This sheet may be used in extensively planted applications as well as in accessible inverted roofs covered with paving stones or slabs.

This sheet amalgamates the functions of water storage and high-performance drainage. Its octagonal dimples additionally reinforced by ribs make it unusually compression-resistant, so that it will sustain even heavy loads safely. Thus, it provides an extremely serviceable and economical foundation for green roofs.

Capable of storing 7 litres/m² of water as a reserve for periods of drought, Delta-FLORAXX is breathable and water permeable thanks to the perforation between the storage dimples. Other features include a compressive strength of 200kN/m² thanks to its innovative octagonal dimples.

Also available is Delta-FLORAXX Top, which has the additional benefit of a filtration layer - eliminating the need for one laying operation.

Sheet size for Delta-FLORAXX is 20m x 20m, while FLORAXX-Top is 10m x 2.1m wide. The extra 100mm geotextile width allows for overlap.

Technal - Two acclaimed buildings featuring aluminium glazing systems from Technal, have won RIBA Awards for architectural excellence
The Snowdon Summit Visitor Centre, and CitySpace, a flagship sports and leisure facility at the University of Sunderland.

Bob Welsh, General Manager of Hydro Building Systems which designs and manufactures Technal façade systems, said, "We are delighted that the design and construction teams responsible for these two exceptional buildings, have been recognised with these awards. Both schemes also demonstrate how standardised façade systems can be used to create visually strong, environmentally sensitive and highly innovative architectural solutions. We would like to offer our congratulations to both teams for producing two really outstanding projects."

Hafod Eryri, the new visitor centre on the summit of Snowdon, is the highest building in Wales and England, and occupies one of the world's most extreme sites. Large picture windows from Technal's FXi65 casement suite are set into deep reveals in the cladding. This 'wall of windows' maximises the magnificent views from the summit, and allows light deep into the centre of the building.

Here, the Technal system uses slim sight lines and is sufficiently robust to perform successfully over time in this harsh environment, which is exposed to wind speeds of up to 150mph, over 5m of rain each year, and temperatures as low as -20°C.

Three variations of Technal's MX curtain walling system were selected to help create a 'dazzling' façade for the CitySpace facility. MX SSG structural glazing, MX Visible Grid, and MX Sloped Glazing give the appearance of bespoke façades but with all the cost, lead-time and performance advantages of a proven aluminium system.

Technal's MX aluminium curtain walling suite provides architects and contractors with a wide range of design options from a single grid system - for simplified specification, fabrication and installation; consistent quality; cost efficiency, and reduced time on site.

The variations include:

- MX Visible Grid - for a more conventional 'grid' appearance
- MX Trame - where the vertical or horizontal profiles are accentuated
- MX SSG - structural glazing for flush glass façades with visibly less aluminium
- MX BG - which uses an externally beaded frame for a 'picture frame' appearance
- MX Sloped Glazing - for sloped roofs, atria, canopies, valleys and pyramids, which are visually consistent with vertical façades
- MX Acoustic - an option for MX Visible Grid and MX Trame Horizontale for applications where additional acoustic performance is required.

Technal - Highly Sustainable Innovation and Test Centre is completed for Façade Products
Hydro Building Systems has opened a new and highly sustainable technical centre for the research, development and testing of its Technical brand of aluminium façade products as featured on FastrackCAD.

The state-of-the-art facilities have already been used to carry out full-scale testing for Technal's latest innovation - the revolutionary MODAL low rise glazing system which was developed in the UK and was the first product to be tested in the new centre.

Located in Toulouse, the 1,600m² technical centre, which represents an investment of £1.8m, provides workshops for prototyping and assembly, testing laboratories, an electronics laboratory, showman, equipment rooms, offices, and meeting rooms.

The building is equipped with three test rigs to assess air, wind and water resistance in line with the latest European standards, for windows up to 4m by 4m, and curtain walling up to 6m by 8m. There is also a unit to carry out mechanical tests for strength and resistance.

The centre was designed to minimise inpact on the environment and carbon emissions. Energy consumption is expected to be as low as 45kWh/m² per year - exceeding Building Regulations requirements by more than 50 per cent. The building's sustainable features include:

- A green roof to the workshop area for additional insulation
- Heating and ventilation provided using a roof-top system that consumes just 1kW of energy for every 3.25kW of heat it produces
- Roof glazing with automatic opening windows to take advantage of night-time ventilation to cool the building during the day
- High levels of natural light, complemented by low energy lighting on two circuits for efficient use and metering
- Technal's MX Trame Horizontale curtain walling system to the south façade fitted with automatic brise soleil to allow shading to be oriented according to the position of the sun
- Photovoltaic modules integrated into the brise soleil sunshading, providing a total surface area of 34m² which will generate around 5,000 kW of electricity each year

Technal's MX Trame system delivers the same enhanced thermal efficiency as the other options in the MX curtain walling suite, but allows specifiers to accentuate the vertical or horizontal profiles across a façade using projecting caps. Specially designed flush gaskets soften the corresponding vertical or horizontal sections. It can accommodate 6mm to 32mm glazing as a flat façade and the Horizontale option can be faceted up to 10 degrees.

David Bailey Furniture Systems - Medical Furniture Manufacturer refurbishes New Dental College
David Bailey Furniture Systems has provided medical furniture at a value of £32,000 for a new block at the first dental college to be built in the UK for over 40 years. The Peninsula Dental College, Truro, Cornwall along with two other dental colleges, fills the gap in the NHS dental healthcare provision for the county.

David Bailey's team of fitters installed the Healthline range at the Truro site in two phases. The clinical rooms were furnished first, with the offices being furnished in the second phase commencing in October 2009 for contractors Interserve Project Services.

Products supplied by the medical furniture manufacturer, David Bailey, included HTM 63 suspended units with HTM 63 bullnosed fully moulded worktops. Half of the worktops specified were from the medical manufacturer's existing Healthline range, and the other half were bespoke stainless steel designed by the Architect for the dental college. A variety of colour schemes were selected for the installation including white doors with grey worktops, grey doors with speckled beige worktops and grey doors with yellow worktops.

The HTM 63 range of fitted medical furniture was originally designed by the Department of Health and therefore offers suspended storage units specifically suited to the requirements of all types of healthcare establishments including hospitals, care homes, doctors' surgeries and medical colleges.

As the new block was built on the Treliske Hospital campus and adjoined the knowledge Spa Medical School it was not part of the main building. This made it easy for the installation team to access the building without too much disruption.

HRH Highness of Gloucester officially opened the Peninsula Dental College in Truro in March 2010. The college includes 32 dental chairs for training, office space and four single surgeries.

David Bailey has previously supplied medical furniture for the Peninsula Dental College in Plymouth, Devonport at a value of over £35,000 during 2008/2009.

Delta Membrane Systems - Delta BBA Renewed
Waterproofing products from Delta Membrane's extensive System 500 range have had their BBA Certification renewed. Four of the products are included in Agrement Certificate No. 00/3742.

They include Delta-MS20 - a moulded HDPE sheet used as damp-proofing on walls, floors and arches to support a dry lining of flooring. It can be employed in new construction or in existing buildings over contaminated or damp background. It has a 20mm stud profile for maximum drainage capacity.

Also covered by the certificate is Delta-MS500. This is a clear moulded HDPE sheet (8mm profile) that can be used as damp-proofing on walls, floors and vaulted ceilings - again in new-build or refurbishment work over a contaminated or damp background. It can be used to support a dry lining or floor.

Delta-FM is the third product covered. Specifically designed to combat dampness and contamination in flooring applications, Delta-FM allows various floor finishes to be achieved thanks to a special low stud profile (3mm) that minimises changes in floor levels but still provides an air gap to achieve damp pressure equalisation.

Completing the quartet is Delta-PT which can be used on internal or external walls and vaulted ceilings as damp-proofing, and as a support for plastering, dry lining or rendering. This high performance polyethylene membrane is extruded into a series of studs to create a continuous air gap behind the waterproof membrane.

On the face of the membrane is a welded mesh which allows plasters and renders to bond efficiently to achieve dry and durable finishes. Dab-fixing of board finishes is also an option.

As you might expect, there is plenty of legislation and advice guiding us the right way to ensure the creation of a basement area to certain standards. For example, BS8102: 2010 is the Code of Practice, which looks at 'Protection of Below Ground Structures Against Water from the Ground'. A more elaborate expansion of this standard can be found in CIRIA Report 139 'Water Resisting Basements'. Measured against these industry standards, Delta's range of membranes are classed as a Type 'C' (Drained protection), and considered the most effective and trouble free option.

Key factors assessed in the Agrement Certificate include resistance to water and water vapour, resistance to salt transfer, resistance to impact, loads, and durability. The membranes are also proof against Radon and ground gases.

Technal Curtain Walling for Breeam Excellent Office Building in Birmingham
Calthorpe House is one of a small number of buildings in the Midlands to achieve a BREEAM (2006) 'excellent' rating. This highly sustainable landmark office scheme features the latest curtain walling from architectural aluminium specialists, Technal.

Designed by Webb Gray & Partners for developers Calthorpe Estates, and constructed by BAM, the £40m building is also the first application of a new adaptation of Technal's MX curtain walling system.

This last façade option is an alternative to structural sealant glazing, which gives the benefit of clear sight lines, no caps, and flush corners for greater transparency and high quality aesthetics with uninterrupted spans of glass to maximise natural light and architectural appeal.

The Technal curtain walling was glazed in green solar control glass as part of the building's sustainability strategy, with a ceramic-coated inner pane to conceal services between floors.

In every aspect of its design and construction, Calthorpe House was conceived as an office scheme that would represent best practice in environmental performance.

The finished building outperforms statutory requirements for carbon emissions by 27 percent and provides a range of energy-saving measures that contributed to the BREEAM (2006) 'excellent' rating. These features include high levels of thermal insulation and ventilation, solar control glass, low noise levels, and a large amount of natural light from the floor to ceiling glazing on the ground and upper floors.

Technal's MX curtain walling suite has all the aesthetic, durability and low maintenance qualities of aluminium, combined with constant 52mm sight lines to create a uniform appearance across a comprehensive range of design options - low to high rise curtain walling; visible grid, ribbon, structural, beaded, faceted and sloped glazing.

Technal helps to create 'Dazzling' Façade for Iconic New Campus Building and 2012 Olympic Training Centre
Architectural aluminium systems specialist, Technal, has helped to create a highly distinctive and complex façade for an innovative new campus building at the University of Sunderland, using three variations of its MX curtain walling system featured on FastrackCAD.

The CitySpace facility, which has been selected by the ODA as an Olympic and Paralympic training camp for London 2012, has also achieved a BREEAM excellent rating.

Technal's MX SSG structural glazing was used to form distinctive coloured rectilinear openings between pre-cast concrete panels in a striking random pattern. This is the first time the system has been used in this way.

MX SSG is a flush curtain walling option which met the architect's requirements for less visible aluminium and clear expanses of glass. Interlayers for the laminated glass in five shades of green give the building a clear identity and provide a strong contrast to the crisp white L-shaped concrete panels on the most prominent elevation.

On the new CitySpace building, linear roof lights formed from Technal's MX Sloped Glazing throw natural light back into the triple height social space and the split-level fitness studio.

The CitySpace scheme has a number of sustainable features which contributed to its BREEAM excellent rating. It benefits from ground source heat pumps, high levels of natural light, rainwater harvesting, passive ventilation, and the use of coloured glass to reduce solar gain.

The building accommodates a range of indoor sporting and social facilities, including a six badminton court sports hall, 70 station fitness suite, sports massage and injuries centre, multi-purpose room, indoor climbing wall, and retail, catering, leisure, seminar and exhibition spaces.

The facility is also a strong addition to the University's support for world athletes following its selection as an Olympic Training Centre for the 2012 London Games. Index

Delta Membrane Systems - Fit for Purpose
In recent years general wellbeing has become more important to the British public at large, and this has resulted in an increase in membership to gymnasia. Indeed, some people are taking the extra step of creating a gymnasium within their own properties, and the basement is the ideal spot for this.

Delta Membrane Systems offers a range of products that will convert a dark, dingy and damp basement into a warm, dry inviting extra space in a house, which could easily be used as a gymnasium.

This product range includes MS-500 - a cavity drainage membrane for use on walls and floors as a waterproofing system. This 0.6mm high density polyethylene sheet features 8mm deep studs which allow effective drainage of moisture from behind the wall finish, or under the floor covering.

Available in a clear option, it gives a compressive strenght of greater than 250kN/m², and is able to drain some 135 litres/min. of water per metre run.

The Delta product line-up also includes Delta MS-20, which has been designed specifically for flooring applications, to protect against dampness and contamination.

Traditional damp proof membranes trap moisture and hold up work while the relative humidity of the concrete takes time to drop. Delta MS-20 allows work to continue immediately after placement thanks to its special stud profile.

One of the applications that benefits from Delta MS-20 is in the installation of underfloor heating, which is becoming an increasingly popular option for the householder.

Sumps and pumps are also available from Delta Membrane Systems, making this company the 'one stop shop' for everything to do with basement refurbishment. Index

Hambleside Danelaw announce CPD tour dates to promote GRP roofing products
Hambleside Danelaw is hitting the road to extol the benefits of GRP roofing products to the building industry.

The Group is participating in the CPD RoadSeminar Tour throughout the UK with dates scheduled for the remainder of 2010. Architects, specifiers and contractors will be able to choose from four different Hambleside Danelaw presentations covering:

- the advantages of specifying GRP roofing systems

- the environmental benefits of choosing GRP

- how green roofs can suit larger as well as smaller projects

- GRP rooflights as the energy saving and low carbon choice.

The first set of seminars provides an overview of what can be achieved with GRP roofing systems and how they differ from alternative systems. They will include information on material safety; installation; new build and re-roofing; features and benefits of different roofing materials; requirements for heritage projects; case studies and considerations for the environment including water run-off.

Maximising recycling opportunities and minimising waste by choosing GRP will also heavily feature as elements of the Hambleside Danelaw presentations. The contents of the presentations have been given a RIBA seal of approval.

The CPD tour follows Hambleside's recent enhancement of its range of Dryseal GRP component based roofing systems for flat and low pitched roofs that come with the easy 'Fit and Finish' installation.

Promoted in partnership with RIBA, the seminars are being organised by the CPD Certification Service, meaning that the content of training courses, papers delivered at seminars and other educationally beneficial material conform to universally accepted Continuous Professional Development guidelines.

Robin Jeffery, Hambleside Danelaw's vice chairman, said: "Hambleside Danelaw is pleased to have the opportunity to explain the advantages of specifying GRP roofing products with their strong environmental credentials as a cost-effective solution in a period of economic uncertainty. Seminar attendees will learn how GRP is durable, safe and easy to install, environmentally efficient and sustainable at the same time as making a building look good."

The Hambleside seminars will be presented by Paul Jubb and the Group's appointed agent for Dryseal, Mike Billett, will be on hand to deal with inquiries immediately afterwards. The venues and dates for the CPD RoadSeminar Tour 2010 are:

- Newcastle (June 10)

Procter Sliding Gate drawings available to download from FastrackCAD
Procter Sliding Entrance Gates have made CAD drawings for its Series 10, Series 20 and Series 30 Pro-glide gates available to download from the FastrackCAD website. This makes it easier, quicker and more cost-effective for architects to incorporate standard and customised sliding gates within their designs. With around 40,000 registered users, hundreds of whom download thousands of drawing files every week, the site is described as Europe's leading provider of architectural CAD drawing databases.

Procter's comprehensive and competitively priced range of sliding gates gives architects and specifiers an exceptionally broad choice of options to suit an almost unlimited variety of commercial, industrial and public sector applications. Moreover, complete customisation is available within the same timescale and cost structure. Single-leaf cantilevered gates can be manufactured up to 8m wide and tracked gates up to 16m wide; bi-parting double-leaf gates can be manufactured for openings up to 16m and 32m wide, respectively.

In essence the Series 10 Pro-glide and Series 20 Pro-glide gates are standard products with customers able to specify the height, width, infill material, finish, security features, automation, access controls and an optional hinged gate for personnel. For applications where complete customisation is desired, the Series 30 Pro-glide gates give architects even greater freedom to enhance the aesthetics and technical specification.

Because Procter's approach to sliding gates gives architects greater scope for turning their ideas into reality, the Pro-glide gate drawings are ideal for making available via FastrackCAD. Architects can download and manipulate the drawings to show the required gate height, width and infill material, as well as incorporating customer branding. If required, multiple concepts can be readily developed so clients can be presented with alternative schemes. By working with standard designs, architects can ensure that the gates represent best value.

Alternatively, where a project warrants a bespoke sliding gate, architects can start with the CAD files for the Series 30 Pro-glide gates, then develop their own gate designs for use in conjunction with Procter's proven actuators and automation systems. Given the complex nature of the overall sliding gate system - which includes concrete bases, steel support pillars, safety fencing and the gate itself - downloading the drawings from FastrackCAD saves architects a considerable amount of work.

Drawings for the Pro-glide sliding gates can be downloaded from FastrackCAD at www.fastrackcad.com (select Procter Sliding Gates from the list of companies) or they can be requested on a CD-Rom from Procter Sliding Entrance Gates.

Shimmering on the City Skyline - One of the 1st Applications of Technal's MX Faceted Curtain Walling is Completed
A new landmark 16-storey tower in Sheffield designed by Cartwright Pickard Architects is one of the first UK applications of Technal's MX faceted curtain walling system.

Developed by Urban l and constructed by ROK, this spectacular fully glazed residential tower has regenerated an important brownfield site on a main gateway into the City and overlooking the River Don.

Fabricated and installed by Dortech, the Technal curtain walling carries clear low E glazing to the vision areas and insulated glass panels with a ceramic coating in a striking palette of four shades of blue. Used in a random pattern for a shimmering effect, the opaque units conceal the building structure and add interest to the face of the building.

The use of the MX faceted option allowed the architects to express the curve of the building, which is accentuated with the specification of smaller panel sizes. The MX system was sufficiently flexible to accommodate both an opening light and a louvered vent in one 850mm wide unit, for uninterrupted floor-to-floor glazing.

Technal's MX curtain walling suite has all the aesthetic, durability and low maintenance qualities of aluminium, combined with innovative façade technology and construction features. Constant 52mm sight lines for the mullion and transoms provide a uniform appearance across the range of options - low to high rise curtain walling; ribbon, structural, beaded, faceted and sloped glazing.

The range of MX CAD Details can be found in the Technal entry on the FastrackCAD database. Index

Delta Membrane Systems - Back to Basements
According to Delta Membrane Systems, it is a misconception that - by definition - basements are dark and dingy areas that cannot be improved.

Tanking, damp-proofing and drainage products available in the Delta range can be used to turn a basement into a warm, inviting living area that can be used for a variety of functions.

Included in the extensive range is the MS-500 which is a cavity drainage membrane for use on walls and floors as a waterproofing system.

Also available is the new MS-20, a brown dimpled drainage sheeting with particularly high drainage capacity and substantial compressive strength.

Traditional damp proof membranes trap moisture and hold up work while the relative humidity of the concrete takes time to drop. Delta-FM allows work to continue immediately after placement thanks to a special low stud profile. One of the applications that benefits from Delta-FM is in the installation of underfloor heating, which is becoming an increasingly popular option for the householder.

Delta Membrane Systems prides itself in being a 'one stop shop' for a product collection that allows the dark, damp, uninviting basement area to be converted into a fresh, dry, useful living space. Index

Delta Membrane Systems - Design Classic
Changes have been made to the MS-20 high capacity drainage membrane from Delta Membrane Systems, with a re-design that brings greater performance characteristics. However, the previous option has proven to be popular enough to keep it in the company's product portfolio.

This means the new variant takes over the name Delta MS-20, with the previous option being re-branded as Delta MS-20 Classic.

Those familiar with the new Classic will know that this dimpled sheet is made from high-density polyethylene, and features studs of a smooth conical shape with flat top. It offers a compressive strength of about 150kN/m².

However, the new MS-20 brings to the market a compressive strength that has been improved by over 30% - boasting figures of around 200kN/m². This has been achieved by changing the profile of the studs from a circular conical design to an octagon in cross-section, and the smooth walls are now ribbed.

Pressure strength is improved parallel to the stress cracking stability which is also upgraded and extends the lifetime of the product.

Speaking about the new introductions; Delta Director Brian Davison states: "We believe in giving our customers the top quality products they demand. When we mentioned the plans to introduce the new MS-20, some clients indicated that they would like to have the existing design as an option. We were happy to cater to those needs." Index

Technal scheme wins UK Aluminium in Renovation Award
A regeneration project in Glasgow featuring curtain walling from Technal, has won a UK Aluminium in Renovation Award.

This latest accolade for Elder and Cannon Architect' acclaimed Castlemilk Stables follows a string of other award commendations and it is the second time a Technal scheme has won an Aluminium in Renovation Award.

The Castlemilk Stables involved the restoration of an eighteenth century listed stable block, which had been severely damaged by fire and the addition of a striking new courtyard extension. This has transformed the building into a vibrant focus for the local community and a catalyst for regeneration in the area.

Technal's Trame Horizontale curtain walling was used for the upper gallery facing the recessed courtyard and contrasts successfully with the natural stone facades of the original stable building that have been preserved.

The glazing system incorporates flush face gaskets to minimise the vertical profiles, creating a frameless appearance. Concealed top hung vents were inserted into the curtain walling to provide natural ventilation.

Hydro Building Systems is the largest supplier of aluminium glazing systems in Europe. Its Technal brand of glazing solutions designs, manufacturers and distributes a fully integrated range of aluminium curtain walling, door, window and low rise framing products. Index

One of the first schools to be completed in Bradford's £400m Building Schools for the Future programme features façade systems from architectural aluminium specialist, Technal.

Designed by Anshen + Allen and built by Educo - a Costain/Ferrovial joint venture - the new Titus Salt School in Shipley for Integrated Bradford was one of four national Pathfinder projects. Since its completion, the school has been voted one of the top six new secondary schools in the UK - the only school in the North of England to be nominated.

The building occupies a narrow sloping site between woodland and the Leeds Liverpool Canal. The design has a monochromatic palette with large expanses of glass created from Technal's MX Visible Grid curtain walling system, to help integrate the more public areas of the school into the surrounding landscape.

The curtain walling was used to form the main entrance, full height stairwells, to enclose the assembly hall overlooking the garden spaces, and to create a large picture window for the breakfast room with 3m spans and integrated brise soleil sunshading.

The MX system also features as 3m high glazed units set into stone next to the 'Spanish steps' - the community approach to the school - and was faceted where it wraps around this building. Here the glazing contrasts with a stone base which adds solidity to the design, helping to reinforce a sense of civic pride in the school.

Technal's FXi65 aluminium casement windows were inserted into both the curtain walling and the stone cladding, for natural ventilation. CD commercial doors were also set into the MX curtain walling for access from the teaching blocks to the garden courtyards. All the Technal systems were fabricated and installed by Quest Solutions.

The school comprises six three-storey wings which radiate off a central 'street', providing a social hub and accommodating informal break-out spaces, with shared school and community facilities located at one end of the spine.

Other architectural features of the new school include a large roof terrace for the art department with 360 degree views, and light toned render to articulate the faculty wings which group the classrooms together in identifiable units and minimise the impact of the building on the skyline.

Technal's MX curtain walling system gives specifiers a wide range of design options from a single grid - low to high rise curtain walling, MX Trame for horizontal or vertical emphasis, ribbon, faceted, structural, beaded, acoustic and sloped glazing. This choice of configurations allows the appearance of the building envelope to be varied and on a single project, with all the advantages of one fully integrated system - consistent site lines and interfaces, simplified specification, ease of fabrication and installation, cost efficiency and reduced time on site.

Technal Launches New Modular Façade System - Set To Revolutionise Low Rise Glazing
Architectural aluminium systems specialist, Technal, has launched a new rapid-build façade system for low rise building applications - and the first in the UK to offer integral opening vents.

MODAL has an innovative modular design, developed to reduce work on site and give specifiers the widest choice of configuration options currently available for façades up to two storeys.

The technically advanced yet simple modular frame uses a unique airtight clip system which is faster to install, provides enhanced weather resistance and allows greater quality control because the frames are fabricated off site.

Launched following an extensive development and testing programme, MODAL is designed to provide robust, stylish and high performance glazing for low rise applications such as schools and colleges, healthcare facilities and leisure projects. Its range of module options also allows more design flexibility for single and two storey façades than ever before, with variations including:

- single, double or triple glazed units - fixed lights - integral opening vents - doors - integrated sliding window and door system - infill panels - compositions, such as vent over panel, vent over fixed light, and glaze-in and glaze-out units within one frame module.

MODAL has a host of innovative new features:

- The design of the system allows integral open-in and open-out vents to be incorporated in the MODAL frame, minimising the visible aluminium and ensuring consistent sight lines - A simple square-cut and screw port construction for the mullions and transoms creates the framing modules, which are assembled with an innovative clip system for a quality finish and time-saving installation - The modular transom and mullion design optimises performance and cost efficiency, and allows a wider variety of infill, glazing and vent combinations. Mullions can span up to two storeys with a wind loading of up to 1200 Pa, transom span up to 2m, and a 100kg load can be achieved with a 1m transom - Sight lines are maintained at 65mm across the MODAL range of options, for a more uniform and modern appearance - The standard 100mm module can be easily adapted to 115mm for refurbishment projects - The system uses a 30mm polyamide break for thermal efficiency and Ucw values in a range of 1.1 - 1.75 W/m2K can easily be achieved - Drainage is concealed, with no unsightly caps on the frame or the vents, making it ideal for school applications - The system is designed for optimum thermal performance and can exceed current Building Regulations.

MODAL is fully compatible with Technal's FXi casement windows, and CD and PXi commercial doors, and is fully tested to BS EN standards for curtain walling.

The system has its own exclusive handles, which are strong, secure, contemporary and ergonomic, and MODAL façades are available in a wide choice of finishes - single and dual colours, polyester powder coated, natural self-colour, anodised, and Cendré - Technal's palette of exclusive flecked gloss colours.

Technal Glazing System chosen for the highest building in Wales and England
A glazing system from architectural aluminium specialist Technal, was chosen for Hafod Eryri - the acclaimed new visitor's centre on the summit of Snowdon, and the highest building in Wales and England.

Designed by Ray Hole Architects and constructed by Carillion, this unique building occupies one of the most extreme sites in the world - 1,065m above sea level, subject to wind speeds of more than 150mph and twice hurricane force, over 5m of rain each year and temperatures of -20°C.

The new £8.3m centre for the Snowdonia National Park Authority provides a café, visitor's facilities and railway terminus. It occupies the same footprint as the previous 1930s building, and has been designed to blend seamlessly into its spectacular setting, and to minimise any environmental impact.

Large picture windows from Technal's FXi65 casement suite were set into deep reveals in the cladding on the west elevation. This 'wall of windows' maximises the magnificent views from the summit. The 2.5m high x 2m wide fixed light windows were angled to reduce glare in the valley below and to provide a degree of solar shading to reduce heat gain inside.

Commenting on the glazing specification, Garry Reynolds, Director of Ray Hole Architects, said, "The full height windows allow us to bring light deep into the centre, and for the first time in the summit building's history, we can do justice to the breathtaking views."

"Our requirement was for the slimmest frame and the largest glazed area possible to allow visitors to take in the summit views. The size and weight of the glass also had to be feasible for future replacement given the project's location and restricted access."

"The Technal system is inherently robust and more than capable of performing successfully over time in this exposed and harsh environment."

Lines of poetry by Gwyn Thomas, the former National Poet of Wales, feature on the glass, and the window profiles were finished in low maintenance anodised aluminium as part of the architect's selection of natural materials for the scheme. Some smaller FXi windows from Technal were also used on the west elevation, to provide natural ventilation.

All the construction materials, including the prefabricated steel structure, had to be transported to the mountain summit by train. Both smooth and rough-cut granite stone was used for the external envelope - the curved walls, roof and floors, and strips of Welsh oak line the interior walls to mirror the stonework.

The building has also achieved a BREEAM 'very good' rating - a significant achievement given the project's mountain location. Over 300,000 people visit Hafod Eryri in the summer months and visitor numbers have already exceeded expectations. Index

New Technal Façade System specified for 2nd phase of Chelsea Academy Campus
Facade systems from architectural aluminium glazing specialist, Technal, have again been specified by AFL Architects. The latest project is the second phase of the Chelsea Football Club Training Academy Campus at Cobham in Surrey, which features Technal's new MX Trame Horizontale curtain walling system.

Developed to provide a new purpose-designed pavilion for youth and community use, the scheme's design is strongly influenced by the adjacent training academy completed in 2007. The main contractor was Leadbitter Construction.

The contemporary palette of materials helps to harmonise the building in its green belt location, and includes brass cladding to the gables and eaves, subtle ochre-coloured rendering and Technal's curtain walling with a horizontal emphasis.

The MX Trame façade system is used on each elevation as high level ribbon glazing to the upper floors, recessed panels or protruding 'boxes' at the gable ends and full height glazing to the entrance and stairwells. This maximises natural light for the circulation areas, gym, offices, dining room and teaching areas.

The Trame Horizontale option was selected by the architects to accentuate the linear aspect across the glazed areas. This was achieved with Technal's innovative system design - projecting aerofoil caps for the transoms and slender face trim gaskets, which soften the vertical sections. Concealed top hung vents were inserted into the curtain walling to provide natural ventilation where required.

Commenting on the glazing specification, AFL Architects, said, "Our aim with the glazing was to articulate and separate the layered elements of the façade and to allow lots of natural day light into the upper floors. We specified Technal's MX Trame curtain walling system, which was used on the first phase, and the bull nose cap to provide a horizontal emphasis across the building. It is visually very successful."

Fabricated and installed by Leay, the curtain walling was glazed in clear low E glass and finished in silver to contrast with the brass cladding. Technal's fixed light FXi65 high performance windows were also used at ground floor level installed into the rendered walls, and CD commercial doors with an anti-finger trap safety device were inserted into the curtain walling.

Also available in a vertical option, MX Trame uses the same grid system as other design options in the MX curtain walling suite for ease of specification and fabrication. It will accommodate 6mm to 32mm glazing units, as a flat façade or faceted up to 10 degrees. Concealed vents can be supplied in top hung open-out or tilt/turn configurations, and MX Acoustic is a further option for MX Trame Horizontale for applications where additional acoustic protection is required.

The first phase of the multi-million pound Cobham development, also designed by AFL Architects, was the world-class training facility for Chelsea FC's first team - one of the most ambitious investments undertaken by a football club. This building was predominantly glazed in Technal's Trame Horizontale faceted curtain walling and featured a curved green roof to help it blend into its rural surroundings. Index

Delta's 'Cleaning Up' Operation
It has been another winter where the physical and emotional impact of severe flooding has yet again made the headlines and those directly affected by the record-breaking rainfalls, are now facing the long task ahead of them - refurbishment.

Delta Membrane Systems has in recent years supplied products more usually associated with tanking work in basements and the like for the refurbishment of flood damaged properties.

The drying-out process often means that householders can remain in temporary accommodation for months, even years. However, Delta Membranes has pioneered a method of reinstatement that dramatically reduces the time families must endure with the disruption to their lives by eliminating the need for traditional drying with resultant cost saving to their insurers. Already successfully employed in Hull, the Delta solution is to create waterproof 'boxes' within the previously flooded rooms.

Delta's PT cavity membrane can be fixed to a damp wall and be 'dot and dabbed' and skimmed, in a fraction of the drying time demanded by traditional methods of remediation. The HDPE cavity membrane ensures air can circulate behind it, picking up residual moisture from the structure over the coming months without affecting the new finishes.

The same result can be achieved on floors, using the Delta FM membrane. It can be loose laid over wet concrete floors and have a new floating floor system installed directly onto it. The 3mm air space created by the membrane again provides the physical separation for the new finishes and allows slow drying without significantly reducing head room. This entire remedial process can be started soon after the flood waters have subsided, bringing a speedy and effective method of returning occupants into their homes. Index

Building Regulation proposals still far too complex to impact positively on environment, says sustainability award winner
Hambleside Danelaw, the British roofing products manufacturer which has won national awards for its approach to sustainability, has warned that the government's latest proposals to amend Part L of the Building Regulations may make little difference in terms of encouraging energy savings and cutting carbon emissions.

The independently assessed carbon negative company agrees with its partners in the National Association of Rooflight Manufacturers (NARM) that the continued over-complicated approach to regulation makes it difficult for Building Control to improve the poor level of compliance throughout the construction industry.

The complexity also means that it is hard for the industry to support architects and designers who are committed to energy efficiency.

While it agrees with the general aim of a 25% target emission reduction (TER) for non-domestic buildings, Hambleside Danelaw feels strongly that the absence of a transparent notional definition for large span buildings from the proposals makes it impossible to comment on whether this goal is sufficiently ambitious. Therefore the definition of a notional building should be clear and explicit, and for large span buildings it should accommodate all possible different uses, such as retail, distribution and manufacturing.

Hambleside is highly critical of proposals to define warehouses as 'non-lit' when most warehouses are now built and toplit with a modern generation of rooflights that can spread diffuse natural daylight throughout a building.

Technological advances need to be recognised
Hambleside Danelaw believes that the proposals do not adequately recognise the recent technological advances in automatic lighting control systems and building products such as rooflights that can really make a positive impact on the green agenda.

For example, it says that the U-value limits for rooflights are too low and could actually lead to an increase in CO² emissions from buildings. Rooflight U-values also need to be based on the whole unit including the frame, because more heat can be lost through certain non-thermal frames than through the actual glazing.

A proposal to restrict the total rooflight area to 15% of a roof because of fears of overheating also completely fails to recognise the reflective properties of modern GRP rooflights and ignores independent research which says that a much more important consideration for overheating is the building's overall ventilation strategy.

Hambleside Danelaw supports the NARM view that technological advances and the need for best practice in all elements of building construction offer a so far missed opportunity to simplify the Building Regulations, at the same time as making the requirements tougher.

NARM wants to see the regulators return to an 'Elemental Approach' and a prohibition on efficiency trade-offs between elements. For many buildings, this means specifying separate performance requirements for each element of the envelope and each building service and control system.

Hambleside’s vice-chairman Robin Jeffery said: "Four years ago when Part L was last being reviewed, we warned that over-complexity in the Regulations would do nothing to tackle the widespread lack of compliance, but lessons don't seem to have been learnt. During that time, the threat of climate change and the need to become more energy efficient has become even more acute and yet we are still seeing an inadequate and unimaginative response from the government. The outcome of this consultation should be a complete overhaul of the approach to regulation and a major switch of emphasis to incentivise the industry to comply via the tax and business rates system."

Hambleside Danelaw is regarded as a leader in bringing innovative energy efficient building products to the market. In 2006 it won a Queen's Award for its Insulator rooflight range and its new Insulator Lighting Control System, which is under development and will be able to reduce the need for artificial lighting inside a building by as much as 50%, has just won a Green Apple award from the Green Organisation.

Renderplas Contributing to Sustainability in the External Envelope
The right choice of PVCu render beads has an important role for sustainability in construction. RENDERPLAS uses 96% recycled material when making ultra light ultra strong PVCu beads and so carries a carbon cost that's a fraction of its stainless steel or virgin PVCu rivals.

Did you know 1 tonne of typical stainless steel generates 3.6 tonnes of CO² RENDERLAS recycled PVCu generates a tiny percentage of this unsustainable amount. Index

Four-Star Eco promotion for Hambleside Danelaw and chance to represent UK in European Environmental Awards for a second time
Hambleside Danelaw Ltd, the UK building products manufacturer with factories in Daventry and Inverness, has been elevated to Four-Star status within the Green Organisation, one of the world’s leading environmental groups.

Membership is restricted to companies, councils and communities that can demonstrate the effective measures they have introduced for environmental benefit and Hambleside Danelaw Ltd was awarded the distinction of Four-Star status as a result of its increased activity and influence to the benefit of the environment.

Ray Khan of Hambleside Danelaw Ltd said: "We are delighted to have been promoted from Three-Star to Four-Star status on the strength of our continuing and increasing commitment to the environment."

A spokesman for The Green Organisation commented: "Hambleside Danelaw Ltd make a significant difference to the environment in their field of expertise and they are actively adopting measures that will continue to improve their environmental performance for generations to come".

"They will be able to use our distinctive green Apple logo on their literature, stationery and livery to identify themselves as a company that is trying to protect and enhance the environment. They will also have access to our library, receive Eco Echo publication and will be able to network with other companies that are doing their best for the environment."

As members of The Green Organisation, they will be helping the independent and non-profit group to continue their own environmental initiatives, including the publication of The Green Book - the annual environmental best practice Work of Reference. The Green Organisation has also organised successful appeals to help the tsunami orphans, Pakistan earthquake victims and it has sent tonnes of recycled clothing, kit and equipment to emerging nations.

The spokesman explained: "The Green Organisation is non-political and non-activist, dedicated to recognising, rewarding and promoting the positive aspects of environmental endeavour around the world. As part of the ongoing work, we organise the annual international Green Apple Enviromental Awards for countries, companies, councils and communities. By publicising their efforts and successes, it encourages others to follow their good examples and realise the commercial and financial benefits that come from adopting environmentally-friendly practices.

Hambleside Danelaw Ltd is on track to represent the UK in the European Business Awards for the Environment, having achieved this honour once before in 2004.

The company has been notified that it is among the major winners in the green Apple Environmental Awards - one of the few accredited feeder schemes into the international campaign.

The Green Apple Awards are now in their sixteenth year and attracted more than 500 nominations this year. Index

Delta Membrane Systems - Wonderwall (and ceiling)
While the Oasis Leisure Centre in Swindon has stood-up well to the tests of time since its construction in 1976, refurbishment work has recently been required - and this was carried out with the help of products from Delta Membrane Systems.

The building itself features a shuttered concrete construction with the roof having a soil bed on which was planted grass seed, over this was placed a glass dome. Internal faces of the concrete showed signs of disrepair caused by seepage of water from the soil area.

Specialist contractor Sovereign Damp Proofing and Construction - a 'Preferred Contractor' with Swindon borough council - was asked to carry out the work and this company recommended a refurbishment solution that involved the use of some 2,800m² of Delta PT.

BBA-Certified, Delta-PT is a high performance polyethylene waterproof membrane extruded into a series of studs to create a continuous air gap behind. On the face of the membrane is a welded mesh which allows plasters and renders to bond efficiently to achieve dry and durable finishes. Dab-fixing of board finishes is also an option. Delta-PT is watertight and resistant to high and low temperature extremes
(-30 degree C to +80 degree C). It will also stand-up to the adverse effects of acids, alkalis, oil and solvents and is approved for use in drinking water applications. The 8mm studs serve a dual purpose - isolating the damp wall from the new plaster and decorative finishes and allowing ventilation of the wall for permanent dampness control. Ventilation gaps located at both the top and bottom of the system allow circulation for this purpose. Alternatively the air gap can be vented externally via a passive air vent installed in the wall.

To further enhance the system's performance the company offers the Delta-PT Profile which can be used at both the upper and lower edges of the membrane. This profile has ventilation slots incorporated into the design to ensure that effective ventilation is provided at all times. The Profile section also acts as a guide for plaster or render coats.

Although primarily employed in internal applications Delta-PT can also be used externally as a waterproof support for rendered finishes especially in exposed situations, where elevations of the building are subjected to water penetrations, salt-laden air or are simply in need of a facelift.

Work has recently been completed by Sovereign Damp Proofing and Construction and the people of Swindon are now welcomed into a leisure centre that has been effectively refurbished using another reliable product from Delta Membrane Systems. Index

Wavin - Hep2o Has Heating Covered
Hep2o the premier flexible push-fit plumbing system from Wavin has introduced a new Radiator Outlet Cover, designed to help with the problem of inward and outward air leakage behind radiators.

The innovative Hep2o HX113 Radiator Outlet Cover is designed to fit securely around a 10mm pipe and is easily installed behind the radiator to cover the area where pipes enter the wall - a place commonly associated with heat loss.

When the pipes are installed into the wall, it is often extremely difficult to seal the gaps left around the pipes post installation. This allows heat to escape and air ingress into the walls results in greater energy consumption, higher fuel bills and unnecessary damage to the enviroment. The HX113 Radiator Outlet Cover is the perfect solution, stopping leakages by ensuring that the vulnerable area is sealed effectively.

Not only does the Hep2o Radiator Outlet Cover contribute significantly to achieving a successful air tightness test as required by the April 2006 revision of the Part L Building Regulation, but the new range also ensures the home is heated in an energy efficient and cost effective way.

Dyson Airblade specified for The Gherkin
"The Gherkin is one of the most iconic and innovative buildings in London. Installing Dyson Airblade hand dryers helps maintain this image and reduce our environmental impact."
Jimmy Dimitriou, Associate Director, 30 St Mary Axe Management Company Ltd.

Standing at 180m, 30 St Mary Axe (a.k.a the Gherkin) is the second tallest building in the City of London. It has become part of the city's famous skyline and home to several major corporations - not to mention an award-winning restaurant on the top floor.

"The building was designed with the environment in mind," explains Associate Director, Jimmy Dimitriou. "It uses natural ventilation so we don't have the air conditioning permanently on and there's 24,000 sq m of exterior glass, so we need very little lighting. But in our washrooms we were still using paper towels - expensive and carbon-intensive to manufacture."

In fact, paper towels were costing the building's management over £40,000 every year and with a bathroom on each of the 34 levels, replenishing and collecting towels wasted man-hours and time. Despite recycling the waste paper, several of the building's tenants asked Jimmy and his team to find an alternative hand drying method.

"Our tenants set-out what they'd like - a hygienic hand dryer that worked quickly and used a low amount of energy," says Jimmy. "The Dyson Airblade hand dryer was the only machine to match this criteria. We've now got a total of 68 units up and down the building."

The new technology has been well received by visitors and tenants alike. "We're pleased with the result," explains Jimmy. "Managing the facilities in a building as large as the Gherkin is difficult - anything that saves us time and money while fitting with the aesthetic of the building is great." Index

Delta Membrane Systems - Going Green?
Take the Terraxx path

With the growing popularity of 'green roofs' in modern construction, Delta Membrane Systems offers Delta-Terraxx as a solution to the challenge of effective drainage and protection.

Capable of meeting a variety of horizontal drainage applications, Delta-Terraxx comprises a dimpled sheet with a fused-on geotextile to form a highly effective drainage layer. Facing up, the geotextile acts as a filter protecting the air gap created by the dimpled sheet underneath. Under a covering of soil, gravel or chippings, the heat-bonded permanent filtration geotextile keeps the dimple structure from being clogged-up by sludge. This ensures that any excess water is drained away completely and freely. This efficient drainage has the added benefit of ensuring the area remains free of frost damage in colder months. The integrated self-sealing edge makes the dimpled sheet easy to lay and helps prevent root penetration. Thanks to the smooth backing, any loads are distributed evenly across the waterproofing surface - allowing workers to walk on any compression-resistant waterproofing layers during the construction phase.

Sheets are simply rolled onto the top of the waterproofing - a laying rate of 1m²/min can be expected. One roll gives 30m² of high performance drainage in a single pass. Delta-Terraxx is capable of withstanding compression loads of up to 400kN/m² - making it equally suitable for roof top walkways, even car parks. Index

DELTA MEMBRANE SYSTEMS - FLOOD DAMAGE
Quick solution to Flood Damage

Recent history indicates that when serious flood damage occurs, occupiers have to leave their homes for considerable amounts of time - months, if not years. However, Delta Membrane Systems offers a package of measures that could greatly reduce the time spent on remediating this problem.

Delta has recently come across such a case in Hessle near Hull. As a result of last year's flooding a family watched water levels rise to first-floor window cill height at their property. The heart was ripped out of their home as the squatters moved in, in the form of dryers and dehumidifiers. Day after day, week after week, these units chattered away, much of it unecessary and a full year after the event the family are still not in their home.

Delta Membranes has pioneered a method of reinstatement that dramatically reduces the time families must endure with the disruption to their lives by eliminating the need for traditional drying with resultant cost saving to their insurers. This prolonged drying out period - a fundamental prerequisite for the adhesion of new internal finishes - can be regarded as an irrelevance if the said finishes can be installed onto a dry substrate which provides physical separation from the damp structure.

Delta's 20 years experience in the use of cavity membranes to create a waterproofed box within existing damp basements and cellars is now being employed to remediate flood damaged properties that suffer from dampness entrapped in the structure.

The PT cavity membrane can be fixed to a damp wall and be 'dot and dabbed' and skimmed in a fraction of the drying time demanded by traditional methods of remediation. The HDPE cavity membrane ensures air can circulate behind it, picking up residual moisture from the structure over the coming months without affecting the new finishes. The same result can be achieved on the floors. Delta's FM cavity membrane can be loose laid over wet concrete floors and have a new floating floor system installed directly onto it. The 3mm air space created by the membrane again provides the physical separation for the new finishes and allows slow drying without significantly reducing head room.

As a result, the house can be returned to its rightful owners more swiftly with less disruption to the family and at a reduced accommodation cost to the insurers.

The enabling works consisted of removing all plaster finishes up to ground floor ceiling height, stripping out the timber floor and replacing it with concrete. Once complete, the installation of the membranes (65m² of walls and 40m² of floor) was completed in just 45 'man hours' or one working week. Immediately, plasters got to work and replastered and skimmed again within a week.

With this method, those who have suffered enough through the misery of flooding can quickly look forward to a warm welcome home. Index

DELTA MEMBRANE SYSTEMS - CPD SEMINARS
Nationwide coverage for Delta CPD Seminars

Two CPD seminars have been created by Delta Membrane Systems to help architects and specifiers better understand the workings of cavity drain membranes and water vapour management.

The first of these seminars is entitled 'Waterproofing - BS 8102:1990' which aims to explore waterproofing and in particular the use of cavity drain and air gap membranes in a variety of different situations from domestic basements to Heritage and historical buildings.

Cavity drain membranes are focused upon, along with case studies of typical problems and how they can be solved and achieving enviromental grades.

Water and water vapour management as defined in BS 8102:1990 is the subject of the second CPD seminar from Delta Membrane Systems. This seminar looks at the use of cavity drainage membranes in new-build and renovation projects, as well as groundwater pressure reduction and ground gas management in new-build situations.

Collection and evacuation of penetrating groundwater is also highlighted and case studies are used to show typical problems and their resolutions.

Both seminars last about 1hr each and can be offered at any premises throughout the country. Index

DELTA MEMBRANE SYSTEMS - TERRAXX
Prestigious projects get the TERRAXX treatment

Highlighting the adaptability of Delta-TERRAXX in horizontal structural drainage applications, a new brochure has been published by Delta Membrane Systems.

Entitled 'Delta-TERRAXX - The problem solver' this brochure highlights several prestigious projects across Europe that have made use of the versatility and reliability of the TERRAXX product.

Featuring a dimpled sheet with a fused-on geotextile to form a highly effective drainage layer, Delta-TERRAXX is capable of withstanding extreme compression loads - up to 400kN/m² - and can be installed at depths of up to 10m. Facing up, the geotextile acts as a filter protecting the air gap created by the dimpled sheet underneath. Under a covering of gravel, chippings or soil, the heat-bonded permanent filtration geotextile keeps the dimple structure from being clogged up by sludge, ensuring that any excess water is drained away completely.

Delta-TERRAXX comes in 12.5m lengths and a generous width of 2.4m which reduces the number of lap joints required. The integrated self-sealing edge makes the dimpled sheet easy to install and helps prevent root penetration, while the smooth backing ensures that any impinging loads are distributed evenly across the waterproofing surface. The added benefit of this material is that it allows workers to walk on any compression-resistant waterproofing layers during the construction phase, while at the same time protecting the waterproofing from mechanical damage and harmful exposure to heat.

Among the projects highlighted in the brochure are the refurbishment of a flat roof to a sports hall, a 'green roof' for an education centre and an underground car park that had a roof forming part of the overall landscape at ground level. Other projects are also featured in the 16 page brochure.

In each of these projects, Delta-TERRAXX has provided the ideal solution to a range of issues faced in the design. Index

Delta FoulMaxx is just one of a wide range of products available from the company to tackle the problems of flooding in basements and cellars. Index

HAMBLESIDE DANELAW LTD - ECOBUILD PRESS RELEASE
Hambleside Danelaw launches market-first rooflight that can micro-generate electricity and a new light control system.

Queen’s Award winner Hambleside Danelaw will launch at Ecobuild 2009 two highly innovative roofing products that exploit the potential of natural daylight to slash energy bills and generate revenue-earning electricity.

Leading the way is a market first: a micro-generation rooflight. Designed in partnership with Solar Source Ltd, the Hambleside Insulator PHOTO VOLTAIC rooflight can offer a U value as low as 0.8 W/m²K and incorporates a micro-generation system that will make a significant difference to energy costs through direct use or tariff feed-in. The UK Government recently announced plans to encourage tariff feed-in following the example set by European partners.

Insulator PHOTO VOLTAIC is ideal for use in industrial or warehousing constructions and is easily installed into the roofscape, being in plane with the overall roof area. With patents pending, this product offers three functions: natural daylighting, insulation and micro generation, which makes it a first for the rooflight market.

Another market first will be the launch by Hambleside of a new self-contained artificial lighting control system. The Insulator LIGHTING CONTROL SYSTEM permits the artificial lighting to be automatically controlled through dimming or switching off according to the amount of measured natural daylight entering the building through an Insulator rooflight.

Developed in partnership with Setsquare Ltd, this light control system utilises the unique properties of the transparent light-enhancing honeycomb which is a feature of Insulator. Clients will immediately see a reduction in their energy bills as savings in lighting control usage normally reach 40%.

Visitors to Hambleside Danelaw’s stand (no. 2375) at Ecobuild will have the opportunity to interact with these new products.

FiberTite and Dryseal systems get a green roof on top
Hambleside’s third product launch at Ecobuild results from teaming up with a nursery to offer a green roof system for the company’s top-performing FiberTite and Dryseal single ply and GRP roofing membranes.

Insulator TIMax - a new translucent GRP insulated wall panel
The fourth and final launch at the show will see a new translucent GRP insulated wall panel arrive on the UK market. Insulator TIMax features translucent glass fibre filaments, which provide a good level of thermal insulation with U values at 1 W/m²K, and the translucent properties of the fibre elements allow natural light into the building.

Robin Jeffery, Hambleside’s vice chairman, said: "Four product launches at Ecobuild demonstrates Hambleside Danelaw’s unrelenting commitment to innovation and sustainability in spite of the recession. With massive potential savings on energy bills, the new products are proof that sustainability makes as much sense economically for the client as it does for cutting carbon emissions." Index

TURFPAVE AND CELLWEB USED ON CAR PARKING PROJECT
Geosynthetics solved a car-parking problem in Knowsley with a combination of their landscaping products.

Their Cellweb Tree Root Protection System; infilled with a clean angular stone, was used to provide a stable platform and reduce the compaction of the sub soils from loadings applied by the car park traffic. The Cellweb system is a no dig solution and is simply installed over the Fibertex F4M Geotextile, which is placed over existing topsoil. The clean stone infill and sidewall perforations of the Cellweb promote vertical and lateral drainage and aeration to the tree roots.

The surfacing needed to be a fully porous system, to remove the surface water runoff immediately, reducing flood risk and also the need for expensive sub surface drainage systems.

TurfPave recycled plastic paving system was chosen as the preferred solution. TurfPave is a plastic grid type unit that can be filled with either grass or gravel to provide an attractive alternative to hard landscaping and surfacing products.

The TurfPave was laid over the Cellweb and infilled with a decorative gravel. This provided an aesthetically pleasing finish to the car park and more importantly a fully porous paving system that allows stormwater to drain through the system immediately providing much-needed nutrients to the surrounding trees.
