EST approval first

PIR insulation manufacturer, Celotex, has received Energy Saving Trust approval for its CW4000 boards – the first ever polyisocyanurate (PIR) product to do so.

To qualify for EST approval, the insulation must meet strict levels of energy efficiency. CW4000 is A+ rated when compared to the BRE Green Guide 2008 and offers zero ozone depletion potential and low global warming potential, as well as making it ideal to sit alongside other EST approved best-in-class products ranging from televisions and ovens to boilers and light fittings.

Previously, mainly traditional insulation materials including mineral wool and polystyrene foam have been included on the approved list of energy saving insulation. Now, with the approval of CW4000, the EST is promoting the numerous additional benefits that modern PIR offers when compared to more conventional products – including achieving thermal efficiency with thinner profiles, a wide variety of available thicknesses, ease of installation and outstanding moisture resistance.

Some Celotex products have also received OFGEM (Office of the Gas and Electricity Markets) approval, as part of a scheme initiated by the Government and administered by OFGEM to recognise products that reduce CO2 emissions. Compliant products are awarded approved for use under the CERT and CESP schemes which obligate the main energy suppliers to deliver energy savings to their customer base. As well as this, all Celotex’s insulation products have been approved by the British Board of Agrément (BBA).

“We are delighted that our CW4000 is the first PIR to achieve Energy Saving Trust approval,” said Paul Evans, product manager at Celotex. “This brand recognition marks the next step in raising awareness of our products among UK consumers. With the EST seal of approval in addition to our OFGEM approval, we will be able to further raise awareness for the brand, particularly in consumer markets.”

Green Hero

Lafarge Readymix has received an International Green Hero wall-shield for its environmental innovation and efforts to extend eco-friendly practice.

The honour, from prestigious eco-champions The Green Organisation, comes on top of Lafarge’s earlier Green Apple award. Jeremy Greenwood, managing director Readymix, a unit of Lafarge Aggregates & Concrete UK, was presented with the wall-shield by Trevor Bayliss OBE – famed for inventing the wind-up radio.

Readymix’s success in the awards comes in recognition of its flooring concrete, Extensia, a more environmentally friendly, low-shrink product which can help reduce the CO2 emissions of construction by 20% compared to conventional concrete.

Jeremy said: “This is a true honour. Being recognised by The Green Organisation for one award is fantastic but to receive Green Hero status is outstanding and just goes to show that all the hard work of our employees has paid off.

“I am so proud of each and every member of the business for all their efforts in extremely challenging times. Innovation has always been at the heart of Lafarge’s philosophy and we also take our responsibility to reduce our impact on the environment extremely seriously.

“Creating products such as Extensia is one way in which we can help fulfil both those commitments.”

Lafarge and Extensia will also be featured in The Green Book, the world’s only work of reference on environmental best practice, distributed globally with the intention of inspiring future ecologically sound innovation.

The judges said: “Extensia uses significantly less energy and materials in its production and has better environmental performance and recyclability throughout its life.”

Its formulation means there is no need to include steel mesh or steel fibre to control drying shrinkage and this absence of steel makes it 100 per cent recyclable.

Its high flexural strength also means it can be laid in thinner slabs, reducing the total amount of concrete required.


Meeting tough standards

Schueco UK has just announced that a range of its latest facade systems has successfully completed rigorous testing to the latest CWCT standard.

The tests, which were carried out by Wintech Engineering, show that the Schueco systems also meet or exceed current BS EN standards for curtain walling.

The systems tested include two of Schueco's best-selling curtain wall products FW 50+ and FW 60+, both of which performed up to, or above, the required standard. In fact, these two systems have already demonstrated their excellent energy-saving credentials by being officially accredited by the PassivHaus Institut.

Additionaly the FW50+.SI (super insulation) version can deliver further heat loss savings of over 7% compared to the standard FW 50+ system with identical glazing. This could mean a considerable reduction in energy costs over the life of a building

The third Schueco system to be tested was the FW 50+SG. This widely specified, structural glazing facade performed equally well against other conventionally glazed FW+ systems, demonstrating that a specifier can be certain that any Schueco facade will be able to meet the latest performance standards with ease.

Sign of the times

Street signage across the UK could be set for a new lease of life thanks to Leeds plastics recycling specialist, sustainableoptions.co.uk.

The company, which is based in Riverside Place, has identified a gap in the British market, and begun producing heavy duty plastic signage. There has already been massive interest from a number of local authorities and talks are now in progress with several.

Marketing manager at sustainableoptions.co.uk, Jo Dell, said: “The recycled plastic signs we have developed are perfect for use with Britain's inclement weather, and the rigours of modern society, because they are rot proof, rust proof, chemical proof and vandal proof, graffiti just wipes off them.

“If you look around, thousands of signs across the country are either rusting, bent, or just rotting. We realised there was a huge opportunity and got our research and development department to produce a range of pilot products.

“Interest at the various trade exhibitions we attended, was massive, particularly from public sector authorities, so we have now moved to full scale production and have great hopes for this product range.”

Sustainable Options' plastics are now used across the world in a variety of ways and have been made into railway sleepers, fencing for heavily waterlogged environments – the Environment Agency is one of their customers – and even funky furniture. The news signs are predicted to last five times longer than wood and are more durable than metal.

“They are also attracting interest from the private sector,” added Jo Dell. “A company which rents out cottages by the sea has bought a range of signs because they withstand the rigours of salty water brilliantly. The possibilities are infinite and to think that most of our source product would once have been destined for landfill. Plastic is now making a real difference to society.”

Warming to the task

Carter Homes has achieved industry-leading airtightness test results at its Boughton development, Nottinghamshire.

In order to achieve comparative results, Carter Homes selected Warmcel 500 insulation from Excel Fibre Technology for one of the five homes, and more conventional mineral fibre for the others.

The properties were tested for airtightness by iRed and Elite Energy, with the Warmcel-insulated home recording a result of 2.93m3/hr/m2 first time – exceeding the required 3m3/hr/m2 without any remedial work. The mineral fibre insulations achieved the 3m3/hr/m2 target after remedial works and re-testing were undertaken.

“It’s great to be able to meet challenging environmental targets first time,” said Matthew Chamberlain, contracts manager at Carter Homes. “The Code for Sustainable Homes and the newest Part L building regulations both have airtightness at their heart, and we’re proud to be able to independently prove that we’re building to these standards.

“This target wouldn’t have been met first time if it weren’t for the use of Excel’s Warmcel insulation. Warmcel has inherent environmental benefits, but with airtightness results like these it’s also proving itself as a real value proposition. I don’t think any other insulation can offer the same combination of cost and carbon savings.”

Warmcel offers airtight performance in two ways – its inherent low air permeability and its installation method which is void free. In addition, Warmcel is manufactured from 100% recycled newsprint, and so sequesters carbon within the fabric of the building.

Neil Turner, Excel’s Technical Director, added: “We’ve long championed the importance of airtightness in insulation, and now new regulations are reflecting our beliefs. It’s great to see real-world studies like this back our evidence that Warmcel really is the airtight insulation of choice.”

Reducing costs

Anglia First Home Improvements, the Norwich based Duraflex fabricator, has recently undergone a comprehensive environmental review of the resources they use from pollution prevention, waste management and recycling.

As part of the review, they’ve recently invested in a Waste Advice (UK) recycling waste compactor for their cardboard and polythene packaging waste.

Kyle Huggins, Anglia First’s environmental manager, said: “As part of our existing environmental policy and our commitment to on-going improvements in our operations production efficiency we wanted to ensure that none of our recyclable polythene and cardboard packaging waste ended up in landfill.

“This simple waste segregation process has also enabled us to benefit from significant cost efficiencies by reducing the frequency in which are skips are emptied.

“We’ve been so impressed with the performance of this relatively small compactor we’ve ordered another machine for our new site in Bury St Edmonds.

“In addition to recycling our packaging waste we’ve also introduced other environmental initiatives that ensure none of our post consumer frames or glass ends up in landfill.

“These easy to implement initiatives have also reduced our waste management costs by 75% saving us over £20000.00 per year.”

Low light efficiency

Conergy PowerPlus modules have shown a ‘surplus’ of 15% in efficiency during a real-life test in UK.

Conergy installation partner Freewatt has recorded real life output figures over the past nine months from two separate domestic homes in similar locations: both have a total power of approximately 3.9 kilowatts, both are located in Lincolnshire, a 30º pitch and do not face any shaded areas.

“The data speaks for itself,” Julian Patrick, managing director of Freewatt said. “In the UK climate and light conditions Conergy panels are producing more energy than those of all competitive modules we used before.”

The test period, from October 2010 to July 2011, showed that Conergy PowerPlus panels produced 2,860 kilowatt hours compared to 2,495 kilowatt hours generated by the panels from another German module manufacturer – an output difference of 15% for the benefit of the Conergy premium modules.

“We can see from these figures, that if the trend continues, the Conergy panels are on their way to producing 4,038 kilowatt hours per year with the competing brand only producing 3,546 kilowatt hours annually,” Patrick said. “This exceeds all expectations.”

An average three-bedroomed home in the UK has an energy consumption of approximately 5,000 kilowatt hours per year. With the Conergy PowerPlus modules, home owners of a 4 kilowatt installation can cover 80% of their energy needs, whereas the competitor’s modules can cover only 70% of the total energy needs.

“This improvement in energy production from the Conergy PowerPlus modules is due to the panel’s optimum low light performance,” Robert Goss, head of Conergy UK said. “They are optimised to make the most of the UK climate which consists of plenty of grey, cloudy days. We are delighted that the real life figures have underlined this since these figures look very promising for the future of Conergy in the UK.”


New generation

A new generation of high performance air source heat pumps have been launched by Danfoss Heat Pumps.

The new DHP-AQ heat pump range offers market-leading seasonal performance, thanks to a unique control system that constantly controls and optimises three key parameters in the product: airflow (efficient variable speed EC fan), the refrigerant circuit (electronic expansion valve), and heat distribution (OPTI technology).

In combination, these create the ultimate in air/water heat pump efficiency, enabling DHP-AQ to perform perfectly at very low outdoor temperatures, keeping a property comfortably heated, as well as providing constant hot water.

The new DHP-AQ air source heat pumps work well in the very coldest winters – even down to -20ºC continuing to deliver a consistently comfortable indoor environment and constant hot water, whatever the weather. This is possible because defrosting technology ensures the energy efficiency and full functionality of the heat pump even during a cold winter. DHP-AQ has been developed by Danfoss in Scandinavia.

Chris Dale, director of Danfoss Heat Pumps, said: “We are expecting a huge amount of interest in our new DHP-AQ range of air source heat pumps, which deliver outstanding seasonal performance and can make a huge contribution to a more sustainable build. Air source heat pumps are much in demand in both the domestic and commercial sectors and this range is set to enhance this even further, due to its high system efficiency, aesthetically pleasing design and range of innovative features.”

The new DHP-AQ heat pumps have been engineered to offer the lowest sound level on the market. They also offer a minimalist, contemporary, stylish design which means they are a subtle addition to the exterior of a building.

Lower U-values

The Fully Sculptured Casement Window in white from Veka can now achieve a U-value of 0.8 using 44mm argon-filled sealed units, following further development from the industry-leading system supplier.

The technically advanced system is widely chosen in some of the world's largest building projects as well as millions of private homes. Designed for those who want the look and feel of quality hardwood frames without the upkeep, the Matrix FS is an integrated PVCU window system that has set the benchmark in the industry.

Veka's sales and marketing director Colin Torley said: “Regulations for U-values have become more stringent, so for us to achieve such a low U-value on our Fully Sculptured Casement is testament to our continued investment in technology and product.”

It's not just the Fully Sculptured that can achieve a low U-value, it has also recently been announced that the Veka Infinity suite of profiles can achieve a U-value of 0.8.

Two layers are better than one

The German Institute for Building Technology has approved Styrodur 3035 CS, Styrodur 4000 CS and Styrodur 5000 CS from BASF for double-layer installation in inverted roofs.

BASF has proven that the double-layer installation of Styrodur C in the inverted roof is possible in terms of construction physics. This means that the inverted roof, which offers several advantages for flat roofs, can be applied to meet particularly stringent insulation requirements as well.

Insulation material thicknesses up to 400mm are now permitted. Thus, future requirements for the insulation of inverted roofs can already be met today. An inverted roof is a flat-roof construction, in which the insulation material lies above the waterproofing, creating a layered structure that combines energy-efficient thermal insulation with long-term structural protection.

This design is made possible because Styrodur C absorbs hardly any water due to its closed-cell foam structure and the foam skin on both sides. Styrodur C has been officially approved since 1978 for use in inverted roofs. Up to now, only the single-layer installation of extruded polystyrene was permitted in inverted roofs.

The insulation panels for double-layer installation must be covered with a water-repellent and permeable separating layer in such a way that most of the rainwater runs permanently and securely off the surface. Thus, existing inverted roofs with single-layer insulation can be renovated so that they comply to modern insulation standards. They can be upgraded at low cost and under any weather conditions by supplementing the existing waterproofing and insulation by a second insulating layer of Styrodur C and by a separating layer.

Also new buildings with particularly effective thermal insulation can now reap the benefits of the inverted roof and so comply to the latest energy consumption standards: in the inverted roof, the waterproofing is protected by the insulation layer against thermal and mechanical stress. So, the service life of the roof is considerably prolonged.

Environmental accreditation

Nationwide Windows has been accredited to IS14001.

The ISO 14001 Environmental Management Standard recognises a company’s environmental processes and impact. It forms part of Nationwide Windows existing environmental policy and commitment to on-going improvement of its operation’s production efficiency and sustainability.

Chris Costall, health, safety and environmental manager at window fabricator Nationwide said: “The benefits of pursuing ISO 14001 speak for themselves in terms of reducing energy consumption, waste and ultimately running costs, making better use of resources and raw materials makes both good environment and business sense for all.

“We’ve recently undergone a comprehensive environmental review of the resources we use, from pollution prevention, waste management and recycling.”

As part of the review, Nationwide Windows invested in a CK Waste Solutions twin-chamber baling machine to ensure none of its recyclable cardboard and polythene packaging waste ended up in landfill.

“We’ve been extremely impressed with the performance of what is a relatively small machine,” Chris said. “Its compaction force is incredible and we’re now receiving revenue for materials we were previously paying to have removed from our site.”

CK Waste Solutions can visit your site and provide free impartial advice on how best to help your company become more environmentally friendly while saving money on ever increasing skip costs.

Sustainable short list

Profile 22 has been shortlisted in the sustainability innovation category of the Sustainable Housing Awards 2011 for its low carbon BRE rated recycled window system Reco22.

The fourth year in succession that the Epwin Group PVC-U windows systems company has achieved a short listing, Reco22 is manufactured solely from recycled material.

Using just 6% of the CO2 in production when compared to profile manufactured using virgin material, the system secured a dedicated A+ rating across all domestic applications from the Building Research Establishment in February this year.

This is a first and to date the only award of a dedicated A+ BRE rating for any window system in any material type. The system also boasts its own listing in the BRE’s Green Book Live.

Achieving a U-value of as low as 0.8W/m2K, Reco22 also delivers significant energy and by implication CO2 savings in life.

Andrew Reid, commercial sales development director, Profile 22 said: “We have a window that in using recycled profile dramatically cuts the CO2 used in production and by combining recycled content with advanced thermal performance will help cut CO2 during its service life.

“It supports the sector in hitting targets in new build in the Green Guide, the Code for Sustainable Homes and for cutting the carbon footprint of existing social housing.”

The Sustainable Housing Awards, organised by Inside Housing magazine and its sister publication Sustainable Housing, focus on the best green social housing projects and innovations. Last year nearly 600 people attended the event, which was hosted by comedian Mark Watson, and in 2009 Jon Snow was the master of ceremonies.

Free light bulbs

Totalight is giving away its new ‘next generation’ dimmable LED lamps in return for a share of the energy savings that they create.

These new lights replace energy hungry 50W GU10 halogens and match them with the latest dimmable capability, yet are powered by just 5.3 watts of electricity. The power saving is considerable, claims Totalight and this is how the company recoups the initial outlay for the lamps, as an alternative to a traditional outright purchase.

To agree the payback, those receiving the lamps disclose the pence per kilowatt of electricity that they are paying and agree the average hours of daily usage. Using these figures, Totalight calculates and agrees a percentage share of the recipient’s future savings. This is then payable on receipt of energy bills over a two-year period, ensuring that from the moment the lamps are installed the recipient is achieving energy savings with no initial cost. After two years, full ownership is transferred to the recipient, who then receives all ongoing energy savings.

Totalight managing director, Mark Blanchfield, said: “We want to make energy saving as simple and achievable as possible. By giving our new lamps away, we smash any reluctance caused by the high purchase price seen currently in the LED market. Our aim isn’t only to save our customers money on their electricity bills, but also to help them to save energy and reduce their carbon footprint helping towards CRC.”

An example organisation replacing 1,000 halogen lamps for Totalight LEDs would save about 90% on their energy bills, cutting £11,000 off each year. In this example the money saving is enhanced by carbon output savings of 41 metric tons per year.

Never-ending improvements

The new Infinity Window System from Veka can achieve a U-value of just 0.80 W/m²K, following stringent testing on the recycled window system.

The Infinity system contains up to 80% recycled material, and its co-extrusion means that all external surfaces are virgin polymer, therefore colour-stable and free from lead-based additives.

The Infinity system, launched last year is an entirely co-extruded system comprising ten window and door profiles, all fully compatible with the existing Matrix 70 system. The U-value of 0.80 W/m²K is achieved using glass units filled with argon gas, and not krypton.

Veka sales and marketing director, Colin Torley, said: “It took a leap of faith for our first client to take the recycled route, but now many others are sure to follow and the industry is now more than ready to accept a recycled product.”

Plastic fantastic

EcoSheet is a new panel, produced in Luton by 2K Manufacturing, and is made entirely from waste plastic.

The UK currently landfills over 4.5m tonnes of plastic every year, with only a small fraction ever being recycled.

EcoSheet’s waterproof durability make it suitable for wide ranging applications across many industries. One prominent usage is in construction site hoarding, with many leading companies such as Willmott Dixon, Miller Construction, Morgan Sindall and Wates all using the product, and national framework agreements with Lend Lease, The Apollo Group, ISG Pearce and ASDA.

EcoSheet also works well in fabrication, meaning it can be turned into everything from desks to exhibition stands to animal houses. Innovative companies are taking this pioneering material into many new areas.

EcoSheet can currently be seen on the Gold Medal winning World Vision Garden at Hampton Court or, less exotically, on a number of construction sites in the form of hoarding.

Window to lower U-values

Window installers looking for a cost effective way of meeting demand for energy efficient windows can now choose WER A rated windows with a U-value of just 0.8 from Clydebank based Enviro Windows and Doors.

The new EnviroFusion window is fabricated by Belfast based Dessian Products. It is based around a slim-line Rehau 70mm frame, transom and sash with thermal insert and a triple glazed, Krypton filled sealed unit fitted by Enviro Glass.

Trade manager Tommy Girvan said: “The frames are designed to compete with standard A rated windows which typically have a U-value of around 1.4W/m2K, so they give installers a significant competitive advantage with only a marginal price difference.

“They are ideal for the new build private and social housing markets where specifications increasingly demand high performance, energy efficient windows and for the replacement market where consumers want an A-rated frame with the added advantage of exceptional sound insulation.

The EnviroGlass sealed units overcome the problems of visual distortion and multiple reflections sometimes experienced with triple glazed sealed units by using Diamante glass for the central pane. They are also Krypton rather than Argon filled which achieves higher thermal performance.

The EnviroFusion window has been fully certified by Certass and come with a full 10 year warranty.

New carbon homes brochure

UK building systems company The Litchfield Group has launched an updated version of its brochure detailing how six star ratings under the code for sustainable homes can be achieved using Sheerframe windows and doors.

The eight-page guide provides advice to housebuilders, social housing providers and private homeowners. It outlines the government’s policy on reducing carbon emissions and explains how buildings can gather points towards star ratings under the nine identified design categories.

Because Sheerframe windows and doors deliver excellent weather tightness and energy performance they can be central towards the achievement of a zero carbon ratings, which requires a category six under the energy element in the code for sustainable homes. In the 4th edition of the Green Guide to Specification published by the BRE Sheerframe PVC frames perform to A and A+ levels, the highest attainable.

Sheerframe windows have featured alongside other Litchfield Group components – ICF Tech walls and Masterdor doors – in a range of landmark developments including the acclaimed Code Level 5 social and private housing development at Brookwood Farm in Woking.

Copies of the ‘Towards zero carbon homes’ – how to reach six star ratings” are downloadable from the group website


Switched on

Verbatim has launched seven new additions to its range of energy-saving LED lamps.

The lamps, which have a service life of up to 35,000 hours, provide between 70% and 85% energy savings over conventional types of comparable light output. They are designed as direct replacements for incandescent light bulbs, halogen lamps and compact fluoresecent lamps (CFLs) in general purpose lighting.

Five of the new products are spotlights with GU10 sockets. These operate from a 200-240VAC grid supply. They have power ratings between 4W and 8W and replace conventional lamps rated from 20W to 60W. Colour temperatures range from 2700K warm white to 5300K cool white and the minimum colour rendering index (CRI) of these lamps is between 75 and 80, depending on the model.

A new MR16 spotlight with a GU5.3 socket operates from 12VAC or DC. The 6.5W lamp can be used to replace 20W conventional types and has a lifetime of 35,000 hours. It offers cools white light at 4200K and has a minimum CRI of 75.

With an E27 (screw type) fitting, Verbatim's new R63 8W spotlight is the most powerful of the new solid state LED lamps. It replaces conventional lamps rated at 60W, providing energy savings of over 80%.

Like the MR16 lamps, its CRI is at least 75, service life is 35,000 hours and the lamp is dimmable.

With the exception of two 5.5W GU10 models, all the new lamps are dimmable.

All Verbatim LED lamps are based on phosphor coatings applied to blue LEDs. This creates a broad spectrum of white light. Lenses within the fixtures focus the light and built-in electrical circuits drive the LEDs efficiently, enabling initial costs to be recovered through energy savings and the exceptionally long service life of the lamps.

In Europe, lighting in homes and businesses accounts for about 20% of all electricity consumption, so conversion to LED lighting has a significant impact on enegy usage and carbon footprint. Unlike CFLs, which contain mercury, LED lamps do not contain hazardous materials.

Verbatim LED lamps are available through major electrical wholesalers and retailers. Suggested retail prices start at £15.70 each, depending on the type.

Warm appointments

Web Dynamics, manufacturer of the TLX range of multi-foil insulation, has appointed two regional specification managers to deliver a better understanding of how multi-foils can help improve the thermal performance of the UK’s housing stock.

Anna Williamson and Dare Oduye have been appointed to create greater awareness and understanding, at a project’s design stage, of the applications and benefits multi-foil insulation can deliver.

Working with architects, specifiers, contractors, procurement managers, LABC and conservation and heritage officers, Anna and Dare will deliver technical and CPD presentations across the UK. The presentations will focus upon issues with current housing stock, changes to Part L and ways of improving insulation to achieve better U-values and air tightness without condensation risk. They will also highlight the points of difference and applications for Web Dynamics’ product portfolio.

Anna Williamson (35) is a qualified architectural technologist with ten years on-site knowledge and experience as a private developer. Anna has a remit to work across the north of England.

Anna said: “This is a fantastic opportunity. I have been passionate about the renovation and refurbishment of older properties for many years and there is a definite need for more understanding of multi-foils and their place in new and existing build upgrades.

“Web Dynamics is a company with integrity in the multi-foil marketplace – they are innovative and inspiring. They develop products that complement the needs of today’s builds and improve the fabric of our hard to treat dwellings in the UK.”

Dare Oduye, 24, regional specification manager for the south of England has a background in architecture and architectural engineering and a holistic appreciation of sustainable building design principles, having been involved in a range of high profile projects. Prior to joining Web Dynamics, Dare also spent two years working as a technical advisor for a major manufacturer of PIR rigid board insulation, responsible for liaising with consultants, technical designers and architects on specific applications of the product range.

Dare said: “Having already delivered a number of CPD presentations for Web Dynamics it is clear that our audience is very excited about the benefits of using TLX multi-foils to improve the energy performance of new and existing buildings. They are in search of innovative ways to achieve an energy efficient building fabric compliant with the increasing demands of Part L without losing valuable living space and multi-foil insulation can do just that.”

Improved thermal efficiency

Delivering a lambda value of 0.021 W/mK, Celotex’s new premium performance insulation has achieved an ‘A+’ rating when compared to the BRE Green Guide 2008, British Board of Agrément Validation and Class O fire performance.

The foil faced polyisocyanurate (PIR) FR5000 board has been developed specifically for use in pitched roofs, floors and walls.

The newly achieved 0.021 W/mK lambda value means that FR5000 can now offer even better U-values. This will allow specifiers to opt for thinner insulation solutions to meet these requirements, improving useable space and reducing material costs. Likewise, for schemes where the utmost degree of insulation is required, enhanced targets can be met with minimal profile thickness.

FR5000 is not affected when exposed to moisture, and it is substantially lighter than these types of products leading to ease of on-site handling and less weight of any waste material to dispose of.

FR5000 also offers a Class O fire rating; the first PIR board with this accreditation. The classification applies across the entire product, not just the foam core.

“We are delighted that the FR5000 series has achieved the lowest ever lambda value for Celotex PIR insulation,” said Paul Evans, product manager for Celotex. “At Celotex, we are always striving to develop the best products, so that contractors, architects and specifiers have access to the best materials for their projects and the new lambda value is testament to this ongoing commitment.”


New brise soleil

A solar shading system has been launched by Kawneer.

The AA130 Brise Soleil system optimises natural daylight within the building and limits solar heat gain and glare for its users.

Kawneer’s new AA130 Brise Soleil system can suite with the company’s 50mm AA100, 65mm AA110 and unitised AA201 curtain walling systems, 451PT and AA4001 framing systems, and AA600TE (thermally enhanced) and AA600TEPlu window series.

It comprises a range of extruded aluminium blades in a variety of shapes (aerofoil and quarter round), sizes (100mm to 400mm), spans (up to a maximum of 6,400mm) and colours (130 standard and 31 metallic, guaranteed for up to 30 years) to suit any project – residential, commercial, education or healthcare – where solar heat and glare is a factor.

Horizontal single-blade options give three angles up to 45º while the horizontal outrigger and multiple blade options give three reaches up to 2,000mm to give design flexibility for specifiers looking for natural over mechanical ventilation, and glazing systems and brise soleil from a single manufacturer.

Integration with Kawneer’s curtain walling, framing and window systems is achieved using specially-designed connection brackets, intended to offer ease of installation on even the most demanding projects.

All elements of Kawneer’s AA130 Brise Soleil system – blades, brackets, outriggers, supporting arms and facade connections – are sustainable as they are manufactured from recycled aluminium billets and can themselves be recycled.

Soon to accompany the new AA130 Brise Soleil system is Solector – new solar shading software that can estimate energy cost savings on an annual basis for initial design consideration. These are calculated based on the solar heat gain avoided due to the Brise Soleil and are expressed as a saving in cooling costs.

Cutting carbon and bills

Both new-build and refurbishment projects can benefit from the Insulating Laminate range of boards developed by Knauf Drywall, which cut carbon emissions and save energy.

The boards also reduce costs through enabling installers to dryline and insulate a property in one operation, which saves time on new-build projects particularly. The improvement to the thermal performance of both walls and roofs results in a rapid payback for the householder, with energy savings of up to £400 a year for the average dwelling.

The range is particularly useful in raising inefficient buildings to modern standards – such as the highest Code Levels for Sustainable Housing – while reducing carbon emissions, making it is ideal for conservation areas where the traditional building facade must be maintained or where design restrictions mean the developer must use traditional methods on new build projects.

Customers can also use boards in the range to deal with warm roofs simply and effectively by dry-lining their lofts – and perhaps gaining more living space as a result. Installing these boards will improve sound insulation and air tightness in dwellings as well as reducing CO2 emissions by up to 2 tonnes a year in a properly insulated solid wall house.

The four boards in the range include: Knauf Thermal Laminate, a polystyrene board with a thermal conductivity of 0.037 (W/mK); Knauf Thermal Laminate (Vapour Check) which has an added layer to reduce the risk of condensation while upgrading thermal insulation; Knauf Thermal Plus, an extruded polystyrene board with the additional benefit of good vapour management; and Knauf Thermal Laminate PIR, a Polyisocyanurate board with a thermal conductivity of just 0.022 (W/mK).
