Super Spacer TriSeal has formed a crucial part of one of Europe’s most eco-friendly buildings.
The Maersk Tower, home to the medical laboratories of the University of Copenhagen, was built in line with Denmark’s historic commitment to becoming 100% carbon neutral by 2050.
It became an instant landmark when it was completed last year thanks to its striking copper shell, the work of superstar architects C. F. Møller and Vienna engineering experts Waagner-Biro.
The futuristic structure incorporates resource-saving measures that include automatic LED lighting, a state-of-the-art eco-friendly cooling system, and rainwater collection for toilet flushing and garden irrigation.
Three-thousand vertical copper-clad fins act as both solar shading and wind protection for the building’s 15 storeys of cylindrically curved triple-glazed facades – where Edgetech’s Super Spacer TriSeal plays a critical role in delivering the building’s exceptional thermal efficiency.
“The Maersk Tower is an outstanding example of how the smallest of components – in this case, warm-edge spacer – can have such a huge impact on a building’s overall performance,” comments Edgetech’s Head of Marketing Charlotte Mercer.
“Together with the stunning glass provided by Berlin-based Glasbiegerei Doring, Super Spacer has helped the building achieve U-values as low as 0.5 W/m2k.
“The sort of curved units that were used on this project demand precise, absolutely parallel application, and that made Super Spacer TriSeal the perfect choice.
“What’s more, Super Spacer’s reflective surface means it completely disappears from view when installed in the frame profile, allowing it to offer world-class performance without compromising the Tower’s dazzling aesthetics.”
The structure has won the Scandinavian Green Roof Prize 2017, the Copenhagen City Architecture Award 2018, the World Architecture Festival Award 2017 in the Higher Education and Research category, and the European Copper in Architecture Award 2017.

Innovative, reliable and widely respected, Hourglass is one of the UK’s leading glass manufacturers – and, over a seven-year partnership with warm-edge experts Edgetech, the firm’s market-leading products have gone from strength to strength.
A fully-automated Super Spacer line has allowed Hourglass to drastically streamline its manufacturing operation, and seen it become one of Edgetech’s biggest customers.
Founded in 1975, Hourglass began life making decorative glass. It expanded rapidly in the decades that followed, beginning to perform all its own bending, UV bonding, laminating, metal work and decorative finishes on-site, and completing work on projects as varied and prestigious as the Royal Barge, the Victoria and Albert Museum, the Tower of London and F1 team McLaren’s Technology Centre.
Today, the Gloucester-based business is able to offer one of the widest selections of bespoke glass products in the country – thanks in part to cutting-edge Edgetech innovation, as Claire Miller, Marketing Director of Hourglass parent group Customade Group, explains:
“Hourglass has built its business on a commitment to constantly pushing the boundaries of glass technology – and Edgetech has played a vital role in helping us sustain that.
“Super Spacer’s outstanding performance ensures our glass units offer market-leading thermal efficiency and structural strength – while Edgetech’s automation technology has allowed us to maintain quality even as we’ve significantly increased the numbers of units we produce. It’s more important to us now than ever before as we plan to grow our glass sales dramatically over the next few years, so strong mutually supportive trading relationships are at the top of our agenda.
“We’ve enjoyed a good relationship with Edgetech over the past seven years and look forward to seeing how it develops in the months and years ahead.”
Chris Alderson, Edgetech Managing Director, commented: “Hourglass is a classic example of success through innovation. Just like the Customade Group as a whole, which has helped put lantern roofs and domestic aluminium windows on the map, Hourglass is a pioneer in its field, and it’s been a pleasure to watch them expand and develop over the last seven years.
“For us, it’s a massive vote of confidence in Super Spacer and the Edgetech brand. When we’re the spacer manufacturer of choice for such a progressive, growing company, we know we must be doing something right. Here’s to the next seven years!”

Globe-trotting Edgetech has returned from a highly successful showcase at the 2018 China Glass exhibition, one of the biggest events in the glazing industry calendar.
Visiting Shanghai from the 19th to the 22nd of April, China Glass draws glazing professionals from across Asia and the wider world to see the latest cutting-edge products, and discuss the key trends and developments reshaping the industry.
This year, the show captured a snapshot of an industry in transition, as Daniel Zhang from Edgetech’s dedicated agent in China explains:
“The glazing market is changing rapidly – particularly here in China. We’re seeing rising demand for energy-efficient products, and for higher-end, better-performing products in general. What’s more, like their European counterparts, Chinese manufacturers are showing more and more interest in automation.
“This year’s China Glass reflected that – and at Edgetech’s, our market-leading spacer products received a huge amount of attention. We showcased the flagship Super Spacer, the TruPlas rigid bar, and a large curved IGU made with our premium commercial-grade product TriSeal, which seemed to particularly impress visitors.
“Beyond the products themselves, there was also a great deal of interest in the broader manufacturing solution that Edgetech can offer – fully-automated lines, world-class technical assistance, finance packages for key customers and more.
“It’s clear that modern IGU manufacturers are looking for both outstanding products and extensive value-added services – and we’re confident that our ability to offer both will ensure we thrive in the years ahead.”
Chris Alderson, Edgetech UK & Asia Pacific Managing Director commented: “As more and more glass manufacturers move towards automation, it’s clear that not just in China but all over the world, there’s huge demand for the sort of speed, efficiency, and excellent all-around performance than Super Spacer and other Edgetech products can provide.”
Edgetech’s Super Spacer is the leading foam warm edge spacer product on the market, offering easy application, 100% memory and exceptional thermal efficiency and condensation resistance. The firm also manufactures an extensive range of other flexible components, including its commercial-focused TriSeal and T-Spacer, as well as a number of rigid products.
The 21-storey tower was the vision of the late Zaha Hadid, the celebrated Iraqi-born architect known for her ground-breaking modern designs. Her work on ‘The Opus’ was characteristically ambitious. She envisaged a hollowed-out cube, apparently floating in mid-air – and the finished result is strikingly close to her original idea, pushing physical and technological boundaries to achieve its extraordinary melting ice-cube shape.
Bringing such a bold and outlandish vision to life required world-leading expertise – which is how Edgetech, and its high-performance Super Spacer® TriSeal™, became involved in the project.
Edgetech Managing Director Chris Alderson commented: ‘The Opus is quite simply one of the most staggering and ambitious architectural projects attempted this decade.
“It’s got a 6,000 square-metre flowing glass facade, a curved, 38-metre long, earthquake-proof glass bridge connecting two towers, and at night the structure is lit up by thousands of individually-controlled LEDs. The bridge section weights 1,000 tonnes alone.
“The building’s central ‘void’ section consists of 4,554 irregularly-shaped dark blue IGUs, the vast majority of which were completely unique. The lower end of that void is bordered by a freely formed glass roof over a multi-story atrium.
“All in all, it was an enormous undertaking – requiring 3D modelling accurate down to the last millimetre, curved aluminium profiles, fastening elements and vast numbers of glass units. More than 10,000 individually curved aluminium profiles were supplied from Denmark and the Netherlands, the glass units were produced in three factories in China, and ultimately the entire 3D puzzle had to be precisely pieced together on the construction site.
“And all that glass called for a very specific type of spacer bar. Firstly, they couldn’t use automated application – virtually every IGU used on the project was a different shape. Secondly, rigid spacers were out of the question – they couldn’t practically be moulded into the weird and wonderful shapes that were required.
“And thirdly, they needed something that offered the highest possible level of performance. In hot climates, in particular, a warm edge spacer has to work hard to hermetically seal the space between the panes. Due to the thermal interaction between hot sunlight and shadows, strong mechanical forces permanently act on the edge compound due to the movement of the glass. What’s more, especially in Dubai, where summer temperatures regularly top 40 degrees Celsius, thermally efficient glazing plays a vital role in keeping the heat out, and the air conditioning in.
“That’s why our premium flexible spacer, TriSeal, was chosen. It is designed specifically for the commercial market, capable of meeting the extremely demanding standards of an architectural masterpiece. It offers world-class performance with its unique triple seal design, incorporating an inner acrylic adhesive seal for immediate unit handling, a polyisobutylene primary seal for enhanced gas retention and low moisture vapour transmission, and an outer silicone seal for structural strength and durability. The flexible foam structure handles both curved profiles and rectangles with ease, while at the same time enabling outstanding thermal efficiency.
“It was the perfect fit for an astounding project – one we were absolutely delighted to be a part of.”
Roof Maker, one of the UK’s leading rooflight manufacturer, is celebrating ten years of partnership with world-renowned warm edge experts Edgetech.
Roof Maker’s extensive product offering boasts exceptional thermal performance, robustness, user-friendliness and style, consisting of bespoke roof lights engineered to be best-in-class.
As consumer tastes have shifted, and demand for premium, high-performance glazing products has grown, the fast-growing firm has successfully positioned itself as the leading roof light supplier to the booming higher end of the market – something which arguably wouldn’t have been possible without support from Super Spacer, the pioneering flexible foam warm edge spacer from Edgetech.
CEO Paul Mildenstein commented: “At Roof Maker, we strive to challenge the idea that all rooflight products are the same.
“We all know that consumers are more discerning and demanding than ever. Today, they want it all – stunning aesthetics, exceptional performance and maximal user-friendliness.
“That’s why our products are triple-glazed as standard, and offer large expanses of glass to maximise natural light – but from a design point of view, that does present some challenges.
“The more glass a product has, the higher the risk of it losing heat and energy – which is what makes Edgetech’s Super Spacer such a vital part of every product we produce. With Edgetech’s help, our products can achieve the best thermal performance of any rooflight in the industry.
“What’s more, Super Spacer is a perfect fit for the more unconventional products we produce, too – like the circular O-Lite rooflight. Super Spacer’s flexibility means we can achieve outstanding thermal performance on a round product, without the need for the expensive and time-consuming bending that would be required with a rigid spacer.”
Edgetech Managing Director Chris Alderson commented: “At Edgetech, we’re never happier than when we’re helping industry-leading fabricators push the boundaries of product performance.
“For triple-glazed units, Super Spacer is ideal. The temperature within triple units, especially when used in roofs, can easily exceed the maximum required of volatile fog tests in current European standards.
With some spacers, this could create a problem – if they’re not compliant with higher international standards they could give off volatiles when overheated. But with Super Spacer, there’s no issue – we’ve successfully tested it from -40 to 85˚C, and it’s stood up to temperatures everywhere from Alaska to Dubai.
“It’s been fantastic watching Roof Maker’s phenomenal growth over the past decade – and we can’t wait to see where their dedication to innovation takes them in the next ten years.”

Industry-leading spacer bar manufacturer Edgetech, a Quanex company, took visitors back to the classroom as they showcased the ‘science of warm edge’ at the FIT Show 2017.
Offering one of the most interactive stands at the FIT Show, Edgetech shared just a taste of the thirty years of fastidious research, constant development and thorough scientific testing used to create the ground-breaking Super Spacer flexible foam spacer bar.
The stand also featured live demonstrations of Super Spacer application, showing how glazed units can be manufactured efficiently and cost-effectively using Super Spacer. To complete the science theme, visitors were also able to pick up a test tube of Super Spacer branded M&Ms.
“We had a brilliant time at this year’s FIT Show taking visitors back to the classroom and behind the scenes of our unrivalled Super Spacer,” comments Edgetech’s Head of Marketing, Charlotte Davies. “Behind all of our products, there is a wealth of research and countless hours of testing to ensure every single parameter delivers only the best performance. Our stringent and thorough research and development programme provides the evidence we need to verify the quality and performance of our products, in addition to over three decades of real-life experience outside the laboratory.”
“As experts and pioneers of warm edge, it was great to come to the FIT Show and share the facts behind the technology through our fun, interactive stand. As veterans of the FIT Show, appearing every year since the event began, we can safely say it has been one of our most successful appearances in terms of quality leads. We were able to leave the NEC having established new relationships with installers looking to gain a greater understanding of the quality inside their products, fabricators who are looking to manufacture IG and leading, established IG manufacturers who want to use the best-in-class spacer bar. With such success, we are already looking forward to FIT Show 2019!”
Founded in 1989, and today forming part of global building products group Quanex, Edgetech revolutionised the industry with the introduction of the game-changing Super Spacer flexible warm edge spacer bar. Currently celebrating a decade of manufacturing at its Coventry headquarters, the company offers a comprehensive range of components for warm edge windows.
Edgetech Super Spacer® customer JWC Group has seen big increases in the number of large units required for bi-folding and sliding doors.
Jim Churchill, Managing Director at JWC Group explains: “Thirty years’ experience in the industry has given me a good eye for spotting trends. The biggest one at the moment is bi-folding doors, the perfect solution for homeowners looking to improve their living areas by merging inside and outside spaces.
“By taking note of end-user trends, we can adapt our product range so it’s focussed on helping our installer customers meet homeowner demand.
“That’s why we started using Super Spacer six years ago. With Window Energy Ratings being so widespread, we needed a product that helped us to offer A-rated, warm edge windows that stand the test of time.
“Super Spacer is a high-specification product and the industry-leading guarantee is a massive bonus that we can give to customers. As well as offering thermal efficiency, Super Spacer is quick to apply, so it gives us the best productivity with reduced labour costs.”
Another trend the Rotherham-based IGU manufacturer and fabricator is looking to capitalise on is coloured profile.
Jim continues: “Homeowners don’t just want white or dark brown windows anymore, they’re looking for more varied and stylish options. That’s why we’ve also invested in a spray shop to help installers offer more PVCu colour choices for end-users. Super Spacer is the ideal product for this trend too due to the unique way the foam material reflects the frame. This simplifies our component stock requirements as we don’t have to carry many different colours of spacer bar.”
Alan Fielder, director of sales and marketing at Edgetech comments: “In recent years the industry as a whole has improved its offering significantly and installers are embracing the opportunities from promoting superior products and diversifying their portfolio for homeowners. This is great to see and a far cry from the days when white PVC was the start and end of the home presentation!
“In times of increasing complexity for the supply chain Super Spacer is simply the best solution – seamless aesthetics for every frame combination in one product.
“Thermal performance is now a given and customers, like JWC, are enjoying the additional productivity, proven durability and aesthetic benefits they have with Super Spacer. We look forward to supporting our customers through many more trends to come.”

As published in Glass & Glazing Products Magazine – December 2016
Chris Alderson, Managing Director for Edgetech UK, talks about the continued trend for bi-folds and wide span sliding doors and the impact they have for insulated glass unit manufacturers.
What the trend for bi-folds means for insulated glass unit manufacturers
Talk to anyone in the industry, and they will tell you that bi-folds and wide span sliding doors remain the biggest growth area. The latest Palmer Report predicts that this will continue to increase, and that aluminium doors are growing faster than PVCu – although both are up.
When we talk about bi-fold and wide span doors, it’s easy to think only about the frames. Systems companies promote the extra height and width they can squeeze out of each leaf, and bigger is better.
Door manufacturers have been looking at ways to improve the thermal efficiency of bi-fold and wide span doors. While Building Regulations require a minimum U-value of 1.8 W/m2K for doors, we are seeing more claims of 1.6 and even 1.4 and it’s the glass units that play a big part in delivering thermal efficiency.
Triple glazed units can be used to increase energy performance, but the extra weight of the glass can be problematic in these oversized units. A 6mm pane of glass in a 1.8m x 2.1m door could add up to eight and a half stone. The alternative is to choose better performing ‘clever doubles’ using warm edge technology. Using double rather than triple glazed units makes door leafs lighter so they’re easier to handle and makes them the first choice for most fabricators and installers of bi-folds and wide span doors.
Weight is an important consideration during the manufacturing process too. Automation reduces manual handling, which is a big benefit for heavier insulated glass units. It also maximises speed and efficiency in production.
However, it’s not just making standard glass units bigger, these oversized IGUs can’t be treated the same as smaller ones. To start with there’s the issue of deflection. A large rigid spacer bar frame is likely to bend and even a small variance could cause the spacer bar to protrude into the sightline. Super Spacer® is designed not to move, the acrylic seal on either side of the bar creates a strong bond with the glass which keeps it in place during manufacture. And Super Spacer references the glass edge as the unit is made so it is perfectly level.
This bond counteracts another possible issue with IGUs. Glass units are subject to cavity expansion and contraction as temperatures rise and fall, and this is exaggerated in larger units. Super Spacer’s flexibility means it can allow for movement which prevents the glass cracking under stress, whilst maintaining its exceptionally strong adhesion to the glass. It does not set under compression, so it maintains its structural integrity in pressure glazing situations and will always look to return to its original shape and dimension.
Customers tell us that large glass units are now making up a bigger percentage of their production. As well as supplying the right products, Edgetech has the technical expertise to support insulated glass unit manufacturers who are facing this change.
As you would expect from the driving force for energy efficient glazing, the Edgetech range of warm edge spacers includes a product that was developed as the ideal system for manufacturing larger units. Super Spacer Premium Plus has led the way in commercial structural glazing. It has been proven in IGUs of up to 15 metres in length without issues of movement or deflection and comes with an industry best 40-year guarantee.
If, as predicted, numbers of bi-fold and wide span sliding doors continue to grow, the importance of delivering large, high quality, energy efficient glazed units will become even more important. Super Spacer Premium Plus offers IGU manufacturers, fabricators and installers complete peace of mind.
Super Spacer Premium Plus is not a new product. It was actually the original version of Super Spacer introduced in 1985 and has shown exceptional performance for large glass units. It’s been used continuously over the last 32 years and has been fitted in massive projects throughout the world.
In 1992, 25 years ago, it was chosen for a new glass atrium of the Royal Alexandra Hospital in Edmonton, Canada. The city often experiences heavy snowfall, severe storms and temperatures as low as -40 degrees Celsius, but inside the humidity is kept at 50 percent to reduce the risk of infection.
For the project, more than 13,000 metres of Super Spacer were processed and to date no glass unit has had to be exchanged, nor any condensation formed on the windows. Super Spacer was specified for another development at the hospital in 2005.
