NEXT Energy Technologies Inc.™ announces a new product that enables windows to harvest solar energy, a breakthrough they say that promises to yield significant environmental benefits and revolutionize commercial building design for decades to come.
“It is certainly not an overstatement to describe this technology as a game-changer with far-reaching implications for architecture and buildings of the future,” said Daniel Emmett, CEO and co-founder of NEXT Energy Tech.
“We foresee a time in the near future when buildings are conceived and valued as much for their energy-generation potential as for the commerce that occurs within their walls.”
NEXT Energy Tech’s transparent solar coatings, which can be easily applied to windows of all types during production, are the result of breakthrough organic photovoltaic materials that are printed in a high-speed, low-cost process.
The printing technique is readily scalable for widespread use by large commercial window firms.
NEXT Energy Tech says the coatings provide an unmatched combination of transparency, efficiency, durability and cost. NEXT Energy Tech recently debuted its technology at Intersolar Europe in Munich, Germany and is currently in discussions with several window manufacturers about launching this game-changing technology into the market.
Emmett estimates that a building sheathed in NEXT-powered windows could produce a significant percent of its energy needs and ultimately enable zero net energy buildings. This would constitute a dramatic reversal, as buildings today consume over 40 percent of global energy.
“NEXT provides the compelling combination of exceptional aesthetics, cost-effectiveness and performance that can deliver real value to building owners and tenants alike,” he said.
“What’s more, the windows look like conventional windows and can be provided in a range of color and light transmission options.” To date NEXT has achieved over 10% efficient devices, has demonstrated feasibility of 30 year lifetimes, and expects to have initial product specifications ranges of 7-10% efficiency and 50%-10% visible light transmission.
“NEXT’s product can contribute to a paradigm shift in the power-economics and climate impact of the built environment,” said Andy Cohen, Co-CEO of global design firm Gensler and NEXT Board member.
“This is what architects have been looking for – an elegant and cost effective solution to help architects meet Zero Net Energy and sustainability goals for the next generation of high performance buildings.
New Performance Enhancement Increases Safety and Reduces Wear Caused by Sliding Door Impact
CRL-U.S. Aluminum’s line of sliding glass door systems gives architects and designers customizable options for building spaces that provide utility and modern design.
An example of this is the company’s Laguna Series Sliding Door System, which has now been upgraded with a new softbrake feature for added performance.
The Laguna Series offers smooth, quiet rollers that allow glass doors to slide effortlessly. The softbrake automatically slows down the momentum of sliding glass doors to prevent impact. It takes effect the last four inches of travel in either direction. This helps ensure product longevity.
A contemporary version of the barn door, Laguna Series features an overhead rail that allows glass panels to slide side-to-side on rollers. An anti–lift component prevents rollers from derailing in order to maximize safety.
This is done by attaching a fixed stop onto the roller mechanism right below the rail. Laguna provides an industrial modern aesthetic and can hold doors—including wood doors—up to 220 lbs. (100 kg).
“As interior environments continue to evolve, we remain committed to engineering and manufacturing advanced glass sliding systems that provide function, safety, and durability,” said Al Eini, brand manager of architectural hardware at CRL.
“The new softbrake upgrade for our Laguna Series serves as an example of how we continually improve our products in response to industry needs.”

New solar control glass by PPG reduces energy use for cooling, lighting – PPG (NYSE:PPG) announced that BUILDINGS magazine has selected SOLARBAN® 90 glass by PPG as a 2016 Money-Saving Product winner in the “Envelope Enhancements” category.
Finalists were evaluated by the BUILDINGS editorial staff for the money-saving qualities they offer to building owners and facility managers in areas such as energy efficiency, water savings and maintenance.
Solarban 90 low-emissivity (low-e) glass is engineered with advanced “quad-silver” coating technology that enables it to combine industry-leading solar control performance with a true neutral-reflective clear-glass aesthetic.
Combined with clear glass in a standard 1-inch insulating glass unit (IGU), Solarban 90 glass has a solar-heat-gain coefficient (SHGC) of 0.23, a 15 percent improvement over Solarban 70XL glass, the industry’s most widely specified triple-silver-coated solar control, low-e glass.
The same configuration produces visible light transmittance (VLT) of 51 percent and an exceptional light-to-solar gain (LSG) ratio of 2.22. Interior and exterior reflectance rates are 12 percent and 19 percent, respectively.
Earlier energy modeling of Solarban 70XL glass on a prototype 12-story office building shows that 10-year energy savings related to heating and cooling can exceed $1.5 million (compared to the same prototype building glazed with conventional clear-glass IGUs) through lower equipment costs and reduced energy use.
Because Solarban 90 glass has better solar control than Solarban70XL glass, architects and glaziers can anticipate even greater energy savings.
In addition to supporting the use of smaller heating and cooling systems to reduce initial capital expenditures and long-term air-conditioning costs, Solarban 90 glass also enables architects to design buildings with larger expanses of glass to promote daylighting, diminish the need for artificial lighting and connect building occupants to the outdoors.
Solarban 90 glass meets requirements of the CRADLE TO CRADLE CERTIFIED™ products program at the Bronze level, which helps architects earn credits in the LEED® green building program for their projects.

researchers, in collaboration with China’s Tsinghua University, have recently created a new set of tools to evaluate the energy performance of large-scale development projects. The tools are a response to China’s rapid urbanization and succession of ever-larger housing and infrastructure projects. The researchers’ goal was to help shape the process of urbanization one neighborhood at a time, producing cleaner energy patterns than would otherwise exist.
The set of tools includes a pattern book of neighborhood typologies from around the world, which have proven to be energy efficient. The research team, led by Dennis Frenchman and Christopher Zegras from MIT’s School of Architecture + Planning, intends for these low-energy forms to replace existing typologies, which were developed without regards to energy performance.
The other tool is an Energy Proforma that uses a single number to represent the lifecycle energy consumption of a neighborhood project. The Proforma compiles 3 types of energy data: how the neighborhood form affects the type and amount of transportation used, the amount of energy used for operations such as heating and cooling and the amount of energy consumed in construction. Ideally this measurement will be adopted as the standard energy assessment within Chinese public policy. This should allow planners and officials to easily compare different development proposals.
The tools were first put to the test this past summer by five teams of graduate students from MIT and Tsinghua University in Beijing. They used the tools to develop proposals for new Clean Energy Neighborhoods in a town being planned on a new high-speed rail line. The designs were assessed to not only be exceedingly energy efficient, but also highly livable. After all, there is no reason why the two should be mutually exclusive.
Introducing the benefits of Thermobar and Thermoflex warm edge spacers, the video commences within a warm comfortable home with a family calculating their energy bills.
It then showcases Thermobar and Thermoflex by zooming into a simulated home and through clever graphics it deconstructs a window down to the spacer bar within the glazing unit.
Quoting figures such as “Up to 80% of energy loss through a window occurs at its edge” and “Warm edge glazing is up to 65% warmer at the edge than traditional windows” the video tells homeowners about the real issues relating to poorly insulated windows and how Thermobar and Thermoflex help to minimise the energy loss through the edge of window glazing to keep the heat in or out of a building as required.
Warm Edge spacers also help to minimise condensation and mould.
Thermobar Warm Edge Spacer is a rigid tube spacer system made with engineering plastic with a gas barrier tape. It has a thermal conductivity value of 0.14W/mK and achieves a Passive House rating of phA for Arctic Climates (phA+ with hot melt secondary sealant).
Thermoflex Warm Edge Spacer is a flexible rubber spacer system with gas barrier tape. Its value is 0.135W/mK and similarly achieves a phA+ rating.
Thermoseal Group’s marketing manager, Samantha Hill tells us: “We are delighted to finally launch our Warm Comfortable Home Video to showcase the advantages of our highest performance UK-manufactured spacer systems – Thermobar and Thermoflex.
With our focus on export, the video will also shortly be available in multilingual versions for customers to use to showcase the products worldwide.
“This video is part of a range of promotional tools that we are due to launch for window installers to use to promote the advantages of windows incorporating Thermobar and Thermoflex warm edge spacers.
We are excited to see the growth in demand of our products and now our spacer bar production sites have a large additional capacity, we are ready to tell the world why our products are best in the worldwide industry.”

When designing with glass, there are a wide range of options to choose from to create a truly unique project. One option in particular—reflective glass—has some significant aesthetic and performance benefits. Even when transparent glass is in vogue, there are specific applications when tinted, reflective glass can be the superior choice. In fact, there are even reflective glasses that provide the solar control benefits of low-e coatings.
Today’s reflective glasses have evolved and now feature varying levels of reflectivity that create a wide range of aesthetics. The mirror box effect is definitely a thing of the past! Below are some key benefits to designing buildings with reflective glass:
- Color: Tinted, reflective architectural glasses offer better harmonization with spandrels, metal panels, extrusions and other building materials. This color enriched glass transmits generous levels of visible light and offers color neutrality, which also enhances the tint of the glass substrate underneath the reflective coating. Today, reflective glasses can also include low-e coatings.
- Visibility: Reflective glass also has a special metallic coating that makes it possible to see out, while preventing people from seeing in, in order to preserve privacy during the day. In addition, reflective glass makes it possible to hide computer wires, vents, fans, HVAC components and other building mechanicals.
- Glare Control: Reflective glass also impacts visible light transmittance (VLT). Reflective glass allows just the right amount of natural light into a building, while at the same time reduces glare and the need for window blinds and other interior shading devices. In addition, reflective solar control glass reflects a portion of incoming solar radiation, which limits heat penetration into the building and can potentially lower HVAC usage.
- Exterior Appearance: Reflective glass provides a bold, crisp exterior appearance, along with a dynamic building surface that changes to reflect the color of the sky, the passing of clouds and the different times of day.
For complete technical information about designing with reflective glass and other glass topics, visit ppgideascapes.com. And for any other glass questions, please contact PPG or call 888.PPGIDEA (888.774.4332).

Planitherm glass can also be used in triple glazed windows – now you can save even more on your energy bills!
Modern windows are being constructed using three panes of glass, hence the name triple glazing.
Triple glazed windows are even more energy-efficient than modern double glazing. The thermal insulation benefit is clearly visible through the additional pane of glass and gas filled cavity.
There are three reasons why you should consider installing triple glazed windows containing Planitherm glass:
Save even more on your energy bills
Triple glazed units have an optimised energy balance to maximise cost savings. Triple glazing allows a high level of solar heat gain, capturing free heat energy from outside during the daytime to warm the home. This is combined with exceptional thermal insulation properties with triple glazed units having a very low U-value* to keep the heat in during night and day. The outcome is a window that well exceeds the current maximum “A” window energy rating.
The thermal efficiency of triple glazed units ensures that cold spots are eliminated. Triple glazed units can also be optimised to deliver excellent thermal acoustic performance – minimising noise levels from outside.
The extra pane of glass ensures that your windows are less easy to break through giving you peace of mind when it comes to security.
Triple glazing is well established in many parts of Europe and is becoming increasingly popular in the UK. Windows are one of the most exposed parts of a house. According to the Energy Saving Trust, a staggering 26% of all domestic heat loss escapes through the windows. Installing energy-efficient windows is essential to help keep the cost of energy bills down.
Double glazed windows containing Planitherm glass provide a highly energy-efficient solution that can save up to 28% on your energy bills**. However, Planitherm in triple glazed units provide the ultimate in energy efficient performance, exceeding the best performing double glazing units. Rising energy prices mean that it has never been so important to save as much as possible on your energy bills. Installing triple glazing will also reduce your carbon emissions.
*U-value reflects the thermal insulating performance of a building. the lower the co-efficient is, the better the insulating performance.

From a distance, the Beijing Greenland Center recently-completed by the Chicago office of Skidmore, Owings & Merrill (SOM) may look like any of the other rectangular skyscrapers that dot China’s capital city. Look a little closer, however, and you’ll see that the tower features an elegant trapezoidal glass facade that’s claimed to improve its energy performance.
Comprising 55 floors, the Beijing Greenland Center is located in the Dawangjing business district and rises to a height of 260 m (853 ft). The interior contains office space and 178 apartments and the building is also connected to an attached multi-story retail zone.
The pattern of the glazed facade is inspired by the bas-relief sculpting technique and comprises two types of trapezoidal Low-E (efficient) glass modules. One tapers upward, the other downward, with the two alternating across the facade, refracting the daylight inside and out.
“The design team sought to create an elegant, eye-catching tower by exploring interactions between simple form, light, and shadow,” explains SOM. “In a response to Beijing’s overcast skies, the tower catches and reflects daylight to enliven the surrounding neighborhood.”
SOM says that the trapezoid glass facade improves the building’s thermal performance, cutting down on solar heat gain compared to a completely flat glass facade.
Indeed, the firm aims for the Beijing Greenland Center to achieve a 30 percent reduction in energy use and water consumption compared to a baseline building, however it’s not clear exactly what this baseline is. Architectural Digest reports that it refers to other towers throughout China, but we’re awaiting comment from SOM.
Besides the glazed facade, the building includes some energy-efficient tech, including variable speed pumps for heating and cooling, an evaporative cooling system, and a thermal wheel (an energy recovery heat exchange system that recaptures exhaust gases and hot air and reuses them for heating).
SOM designed the master plan too, which aims to improve walking and bicycling in the area, while a new park includes amenities like cafes and recreation facilities. The firm’s San Francisco office is also in the process of completing three other towers nearby.
Beware this new Los Angeles attraction if you’re afraid of heights. I know I am because nope.
The Skyslide, a glass slide fixed along the tallest building west of the Mississippi River, is open for business this weekend. Thrill-seekers can pay $25 to slide down 45 feet of bulletproof glass nearly 1,000 feet in the air.
The strength of the glass is enough to withstand hurricane winds and an earthquake, according to the BBC.
The slide is a part of OUE Skyspace LA, a rooftop observatory that gives visitors 360 views of the city at the top of the US Bank Tower. This is a great idea for people who want a high vantage point to view the expanding metropolis, and the slide works for people who don’t think that’s enough.
As someone who just moved to Los Angeles, though, you won’t see me going down it anytime soon. And I used to love slides. If the slide was able to freak out an Associated Press reporter who says she’s jumped out of planes, then
I’ll just watch the video where you can see Myers go down the slide and—okay that’s enough slide for me.

The Smart Glass Windows Market has gone from strength to strength in the last number of years due to a number of factors. Recent researchin America has shown that the market is set to be worth 5.81 Billion USD by 2020.
This is an industry that is constantly innovating and the emergence of new improved technologies is driving greater demand for these products. But what are the main drivers facilitating such growth in the Smart Glass Windows market?
1. Recovery of the construction sector
During the economic downturn the sharp decline in the construction sector resulted in a fall in demand for all construction related products including smart glass windows. However, recent improvements in the worldwide economy and the construction sector as a whole has seen an increased need and demand for smart glass windows products again. More and more commercial building projects are adopting smart glass windows for office buildings, hospitals and universities and this trend is only set to continue as recovery of the construction sector persists.
2. Increased regulation with regards to energy consumption
As buildings are responsible for 40% of energy consumption and 36% of CO2 emissions, regulation in this area has increased. Windows have always been associated as the least energy efficient building components. In fact studies have shown that 23% of energy for commercial buildings is lost through inefficient windows.
To counteract this energy loss, many industries have turned to smart glass windows to help them meet their obligations. In introducing this technology, property owners are enjoying financial savings too. The energy efficient smart glass windows serve to decrease costs such as lighting, heating and air conditioning.
3. The number of its applications continue to rise
As technological advancements have increased, so too has the number of applications of smart glass windows. In addition to featuring strongly in commercial design, smart glass windows are also now a prominent feature in residential buildings, automotive, aerospace and the marine industry.
The automotive industry uses this technology to reduce unwanted light and glare on passengers when they are driving. Numerous aircrafts use this technology to prevent cabin heat build-up and block UV radiation to protect interiors. Residential buildings use smart glass windows to reduce heating and cooling requirements or minimize glare in a TV room. Finally, the marine industry uses this technology to control the amount of heat, glare and light passing through windows, doors and portholes etc.
4. Relatively low cost
Technological advancements have also resulted in the steady decline of the costs of smart glass windows. As production methods become more streamlined and the cost of the various materials used decrease, the cost of smart glass windows is becoming far more affordable.

Scientists have developed new solar cells thinner than human hair and flexible eno ugh to wrap around a pencil that could power wearable electronics like smart glasses.
The thin cells can be integrated onto frames of glasses or fabric and might power the next wave of wearable electronics, researchers said.
“Our photovoltaic is about 1 micrometre thick,“ said Jongho Lee, from the Gwangju Institute of Science and Technology in South Korea.
One micrometre is much thinner than an average human hair. Standard photovoltaics are usually hundreds of times thicker, and even other thin photovoltaics are 2 to 4 times thicker.
The researchers made the ultra-thin solar cells from the semiconductor gallium arsenide. They stamped the cells directly onto a flexible substrate without using an adhesive that would add to the material’s thickness.
The cells were then “cold welded“ to the electrode on the substrate by applying pressure at 170 degrees Celsius and melting a top layer of material called photoresist that acted as a temporary adhesive.
The photoresist was later peeled away, leaving the direct metal to metal bond.
The metal bottom layer also served as a reflector to direct stray photons back to the solar cells.
The researchers tested the efficiency of the device at converting sunlight to electricity and found that it was comparable to similar thicker photovoltaics. They performed bending tests and found the cells could wrap around a radius as small as 1.4 millimetres. The team also performed numerical analysis of the cells, finding that they experience one-fourth the amount of strain of similar cells that are 3.5 micrometres thick.
“The thinner cells are less fragile under bending, but perform similarly or even slightly better,“ Lee said.
Other researchers have earlier reported solar cells with thicknesses of around 1 micrometre, but have produced the cells in different ways.
The new method developed by Lee and his colleagues may be used to make very flexible photovoltaics with a smaller amount of materials.

Toughened safety glass can play an obvious role in financial institutions, hospitals, prisons, cash businesses and other commercial properties where security is a primary concern. However, toughened glass is also becoming a much more prominent feature in office design in the U.K. Commercial designers are increasingly integrating toughened glass panels and partitions into office interior design for a number of key reasons.
Durability Enables Flexibility
Toughened glass panels are very versatile due to the strength and thickness of the glass. They offer the strength and durability to withstand wear and tear in a busy office environment. Toughened glass therefore allows designers to consistently push the boundaries of office design by offering flexibility of functionality. For example, designers can use toughened glass to create walk-on glass floors in an office building, table tops, shelving, facades and even furniture.
Disperse Natural Light Without Compromising Security
Allowing natural light into a workspace is essential to improving the well-being of employees. However, lack of natural lighting is one of the biggest problems faced in office design.
In high rise office buildings, designers are also faced with security concerns. Glass windows need to be present to relay natural light but also need to be durable enough to support staff or customers potentially pressing or leaning against the glass.
Toughened glass windows offer the perfect solution. The glass can maximise the dispersion of natural light and at the same time offer support to withstand heavy impact or pressure, alleviating security concerns in high rise office buildings.
It Doesn’t Deter From Aesthetics
Extensive use of glass in office design is extraordinarily popular as it offers a distinct contemporary appearance and a wonderful aesthetic. Toughened laminated glass, although offering greater durability and thickness, does not deter from the aesthetic of an office building.
Most people assume that the additional strength and durability of toughened glass panels will equate to a bulky appearance but this isn’t true. Toughened glass can even be curved, tinted and shaped to further complement the office design.
Maximise Privacy & Productivity
Glass wall partitions can be used to create a private space within a busy office environment when they are formed with tinted, coloured, patterned or frosted styles of toughened glass.Laminated toughened glass partitions are very effective at preventing noise pollution and can therefore create a more effective, productive workspace.
Laminated toughened glass can even reduce outside noise, especially near busy areas such as motorways, main roads and airports.
Toughened safety glass maximises energy efficiency as the thicker glass layers help to prevent heat escaping through your windows and doors. Toughened glass doors and windows will not only save on energy costs but can also make future rearrangement of the office easy, cost efficient and speedy. They require very little or no structural treatment and are easy and quick to install.

Welcome to the Breathing Skins Project
Have you ever seen a building that breathes through thousands of pores? That may now be a possibility thanks to Tobias Becker’s Breathing Skins Project. Based on the concept of biomimicry, the technology is inspired by organic skins that adjust their permeability to control the necessary flow of light, matter and temperature between the inside and the outside. In addition to these performative benefits, the constantly changing appearance of these façades provides a rich interplay between the exterior natural environment and interior living spaces.
The façades work by increasing or decreasing the size of the apertures that are scattered across the surface—much like the skin’s pores would open up or constrict. On every square meter of a breathing skin façade, there are 140 air channels which are described by Becker as “pneumatic muscles.” These circular apparatus essentially inflate, and this collective inflation or deflation is the controlling factor behind the façade’s permeability. As a form of responsive architecture, the ever-changing pneumatic muscles allow a specific amount of air, light, and visibility according to the users’ preference.
The technology mainly consists of two glass surfaces sandwiching the pneumatic muscles. In the area between the two glass panels, only a slight underpressure is required to opening each muscle. Becker thus claims that operating a breathing skin façade would require minimal energetic input. This sophisticated yet simple innovation allows the façade to be free of any visible technical components, providing a sleek and seamless finish.
Breathing Skins began as Becker’s diploma thesis at the University of Stuttgart. Since then, the technology has been further developed with the support of academics and sponsorships from companies, institutions, and foundations. Becker’s project is now showcased in a fully dedicated showroom in Mandelbachtal, Germany, built in partnership with Simon Huffer.
The showroom shows the possible effects of a Breathing Skins façade. The actual shape of the glass panels appear to be limitless, appearing as either flat or sinuous curved surfaces, while the coloration of the “pneumatic muscles” can be either translucent or opaque, showing the customizability of the product. The product’s beauty is imparted by its ever-changing appearance throughout the day. As parameters change, the façade takes on a sculptural spirit that makes it look like an art installation. Perhaps, down the road, further innovations could be made with with more colors to choose from, creating a whimsical stained-glass effect, or interactive projecting screens.
The project has won numerous awards with the most recent one being a nomination for a Green Product Award, exhibiting its incredible potential as an option for building projects to come.
A perfectly balanced counterweight system, plus rear mounted electrical fans, keep this innovative window and facade cleaning machine parallel to the building.
2 Broadway in New York City is a high-rise office tower that opened in 1959 and was renovated in 1999. As part of the renovation, a new glass curtain wall with stainless steel mullions was installed replacing operable windows.
The original window cleaning method was completed by two window cleaners using a portable scaffold supported by a roof davit system. Due to the various setbacks on the building, the cleaning of the entire building was difficult and resulted in excessive wear and tear on the scaffold resulting in downtime and extended cleaning cycles.
Cleaning contractor PBM decided to try an alternative window cleaning method using a self contained, remote control window washing machine built by Sky Pro Window Cleaning Systems. “We were able to clean areas of the façade which previously had been unreachable,” said Mathew Thompson, Senior Vice President of PBM Technical Services. “We were able to reach these areas by utilizing the rolling outrigger designed. The unit cleaned all of the façade including the stainless steel mullions and windows as opposed to the traditional method in which only the windows were cleaned.”
With the new method, Robert Thomson, 2 Broadway’s manager was able to slash his cleaning budget. “We reduced our cost of window cleaning services by approximately $50,000 per year. The cost for manual window cleaning was approximately $199,000 per year. We also reduced our liability exposure by not having “bodies” over the side of the building.”
While traditional window cleaning methods are viable options that are still commonly used in today’s cleaning applications, the benefits experienced with an automated system allows users to simultaneously improve safety initiatives, reduce costs and maximize cleaning results. Manual window cleaners are challenged with the fact that each building is different, so they must decide the best course of action for each individual descent. Traditional window cleaning is a slow, steady process that necessitates precision when adjusting a boatswain’s chair or scaffolding. These adjustments must be made each time workers are ready to move on to the next section, creating additional downtime that decreases productivity,
The system that PBM chose requires only two people to operate. An operator on the roof raises and lowers the unit using a hoist motor and moves the unit and rigging as each section is cleaned. A second operator on the ground also helps move the unit from section to section. These systems eliminate the need for employees to dangle over the edge of buildings.
“With manual window cleaning, the 1.6 MM sq. ft. 2 Broadway building would take 4-6 months to clean depending on the weather. With Sky Pro, we were able to complete the window cleaning cycle in 45 days,” said Thompson.
The detached brick built dwelling is arranged over three floors with many architectural features. Constructed c1930’s, the house had not been modernised in over 30 years and its new owners were keen to make their mark with an impressive, contemporary scheme utilising a range of materials and design features. One such feature was the use of rooflights to allow more natural light to penetrate a ground floor bedroom whilst also being sturdy enough to walk on from the balcony area above. Xtralite was chose for its ability to provide high quality rooflights and robust solutions to rooflight issues.
Of prime consideration during the project was the necessity for the rooflight to be ‘walk on’ and Xtralite was able to provide the perfect solution to this with its X Glaze traversable rooflight, which also delivered thermal qualities and strength.
Rohith Singoor, Contracts Manager for Vascroft Contractors Ltd commented: “Fulfilling the client’s wishes in terms of allowing natural light to flood into the room below and retaining heat was of the utmost importance and we were confident that Xtralite would be able to deliver this. Its X Glaze product with glass construction allowed the rooflight to be robust enough to cope with regular foot traffic on the decked balcony/flat roof above.”
The walk on units, which are able to be fitted directly to a builders kerb comprise a of a 44.9mm double glazed glass system and a versatile monopitch which has a double glazing unit of 28.4mm. All units have a low E coating and are Aron filled to give a U value of 1.1W/M2Ko. In this case all frames were specially polyester powder coated to match the client’s choice of vertical glazing.
Jim Lowther Sales Director for Xtralite commented: “This specialist commission gave us an opportunity to not only showcase our product and its light permitting and heat retaining capabilities, but also show them in a design led refurbishment that required great strength to allow foot traffic in this flat roof/decked scenario. Our X Glaze product provided the perfect solution offering easy installation and was aesthetically pleasing.”
Rohith Singoor concluded: “The Xtralite team delivered the perfect solution for us and we, and our client, are delighted with the way in which it blends seamlessly with both the internal and external designs giving huge aesthetic appeal to this striking renovation project.”
