Outstanding longevity, durability and thermal efficiency from Super Spacer® T-Spacer™ SG

It was already one of the world’s most outstanding flexible warm edge spacers – but now, Edgetech have launched an even better version of their celebrated Super Spacer® T-Spacer™.

Super Spacer® T-Spacer™ SG is a metal-free, silicone-based warm edge spacer made of structural foam with an integrated desiccant, that’s been designed for the toughest commercial applications.

On demanding glazing projects using extra-large glass panes, its extremely durable edge seal guarantees decades of exceptional performance and stability.

T-Spacer™ SG offers enhanced shape memory, which is critical for the long-term integrity of the edge seal. Its elastic structural foam follows climate-related movements of the glass, relieving a large proportion of the load from the butyl seal.

This is a huge advantage in parts of the world that experience fluctuating temperatures.

T-Spacer™ SG also follows in the long-established Edgetech tradition of offering superb energy efficiency, achieving thermal conductivity of just 0.19 W/m2k – much lower than the commercial metal and hybrid rigid spacers on the market.

“Structural glazing continues to be hugely in demand, and Super Spacer® T-Spacer™ SG is a world-leading spacer product for the toughest commercial glazing projects,” comments Edgetech Managing Director Chris Alderson.

“We’ve taken the hugely successful template provided by T-Spacer™ Premium Plus, and improved it in a number of ways, to produce what we’re confident is one of the world’s best flexible spacers.

“What’s more, we’ve adapted the typical T-shape warm-edge spacer design to make SG even easier to use with automated IGU manufacturing lines.

“We’re delighted to be bringing Super Spacer® T-Spacer™ SG to market, and look forward to seeing it incorporated in ambitious commercial glazing projects all around the world.”

COVID-19 Edgetech Shutdown Update

COVID-19 Edgetech Shutdown Update
14 April 2020

In light of the escalation in the government’s guidance regarding the COVID-19 situation, we took the decision on 24th March to temporarily shut down the business for 3 weeks so that our employees could all adhere to the government’s guidance not to attend work unless absolutely necessary.

We have been closely monitoring the government statements since then and, based on the expected continuation of the strict social distancing rules, we will not be manufacturing for a further period beyond originally communicated.

In order to support our customers who are still operating during this time, manufacturing important products for construction of NHS medical facilities etc, we will be servicing some limited orders on a collection only basis at specific times. To discuss placing an order for collection please contact Tony Palmer on or 07738 800779 as soon as possible. By putting this into place we are able to keep our employees safe while balancing the need to keep our customers running as they undertake their crucial work.

We are continuing to monitor the situation and we will communicate as soon as we are able to bring our employees safely back into the facility to restart manufacturing and when we are able to ship out orders again. All major service updates will be posted on our website so please bookmark

I will hopefully have more positive news to share on my next update but until then, I hope you stay safe, look after yourselves and each other.

Kind Regards,

COVID-19 Edgetech Shutdown

In light of the escalation in the government’s guidance regarding the COVID-19 situation, we have taken the decision to temporarily shut down the business for 3 weeks from 25 March so that our employees can all adhere to the government’s guidance not to attend work unless absolutely necessary.

We have been closely monitoring the situation and advice over the past weeks and taking steps to keep our employees safe while balancing the need to keep service levels consistent for our customers. Our decision on this has not been made lightly but at this point, we believe that doing the right thing is now to close our business to keep our employees safe by enabling them to fully adhere to the government’s guidance not to attend work unless absolutely necessary.

We will continue monitoring the situation during this time and will review this decision during the third week, week commencing 13th April. We will then update our communication on how we will proceed based on government advice at that point. All major service updates will be posted on our website so please bookmark

It is our sincere hope that if we stand behind the guidance as a nation it will help us to be able to return to normality at the earliest opportunity.

I hope you and your families stay safe and look forward to when we can put this unsettling time behind us.

Kind Regards,

Chris Alderson

If we’re going to hit net zero by 2050, we need a retrofit revolution

Edgetech Managing Director

A new study shows that homes in many European countries are three times as thermally efficient as Britain’s. Edgetech’s Chris Alderson argues it’s yet more evidence the UK needs a retrofit revolution.

Last year, Britain became the world’s first major economy to commit itself to going carbon neutral by 2050.

Now, new research has highlighted the scale of the challenge ahead of us if we’re going to achieve that extremely ambitious target.

A study of 80,000 homes by German tech firm tado GmbH found that British properties lose heat up to three times quicker than those in other European countries.

Researchers measured how much heat homes from each country lost over five hours when the temperature inside was 20°C, and the temperature outside was 0°C.

The average Norwegian home lost just 0.9°C. German homes lost just 1°C. Sweden, Denmark and Austria were close behind at 1.2°C.

But the average for British homes lagged far behind at 3°C.

Britain’s ageing homes

There won’t be a single, simple explanation for the gulf that separates homes here and those on the continent – but one key factor is likely to be the age of Britain’s housing stock.

According to a 2015 survey by the Department for Communities and Local Government, 20% of Britain’s houses were built before 1919, and 30% were built before the Second World War.

In Europe, it’s a different story. Huge swathes of the continent were destroyed in the War, which meant many towns and cities had to be rebuilt and went on to offer more modern standards of energy efficiency as a result.

While some parts of the UK underwent heavy bombing, our housing stock survived the six-year conflict relatively unscathed.

The race to decarbonise by 2050

But the reason those figures are so significant is that decarbonising UK homes is vital if we’ve got any chance of meeting that 2050 target.

Home energy accounts for around 20% of our total carbon emissions, with three-quarters of it produced by space and water heating – which would be enough to make thermal efficiency a key priority even on its own.

Thermal Imaging

But it’s made even more critical by the fact that other sectors of the economy are much harder to decarbonise – making big leaps in home thermal efficiency will be difficult, but nowhere near as hard as achieving the same in farming and aviation, for example.

So far, though, the government seems to be focusing on ensuring thermal efficiency in new-build properties, rather than existing ones.

From late 2019 through to February of this year, it ran a consultation, designed to help decide how Building Regulations change in light of the 2050 target.

At the time of writing, the government appears to favour a course of action that would cut the carbon output of UK new builds by 31% using solar panels, air-source heat pumps, and other high-tech solutions. The GGF voted to endorse those proposals earlier this year.

However, there also needs to be a major focus on retrofitting existing properties – and bringing them closer in line with the levels of thermal efficiency seen in Norway, Germany and elsewhere.

The retrofit revolution

We need to be clear about the scale of the challenge. Four out of five of the homes people will live in by 2050 have already been built.

Research by the Institution of Engineering & Technology and Nottingham Trent University estimates that around 26 million UK homes need retrofitting between now and 2050.

And as an industry and as a society more broadly, that means we need to be doing everything we can to make that happen. It’s an enormous challenge, but with enough commitment, it’s very possible.

In the Netherlands, they’ve been experimenting with a radical but highly successful approach they call Energiesprong – ‘energy leap’ in English.

Its proponents have calculated that although more costly in the short-term, it’s far more effective to comprehensively retrofit homes in one go, rather than doing it in fits and starts.

As part of the Energiesprong process, homes are able to achieve near carbon-neutrality with the installation of rooftop solar panels, and a highly thermal efficient external envelope.

The only catch – it costs around £60,000 per home.

Government has to lead the way

As an industry, there are steps we can take to help the UK achieve net-zero by 2050.

The widespread adoption of installation products like Trufit – our impregnated installation tape, which delivers much greater thermal efficiency than silicone – would have an impact.

So would selling the benefits of triple-glazing, ‘clever’ double-glazing and solar control glass.

But given the scale of the challenge, and the enormous costs involved, it’s clear that we’re never going to achieve that net-zero target without huge government investment.

The cost of a comprehensive retrofit is far beyond what most homeowners could afford – and without incentives, it seems highly unlikely that many would take those drastic steps even if they could swallow the cost.

In other words, we’ve all got a part to play in reaching net-zero – but the government has to take the lead.

Online and in person, putting customers at the centre is Edgetech’s highest priority

Edgetech Charlotte

Edgetech’s Head of Marketing Charlotte Mercer explains how the warm edge pioneers are embracing technology to deliver outstanding customer service

The future of shopping is online.

Retail has already been rocked by the rise of Amazon and its equivalents, and we’ve seen household names suffer. Traditional retailers are more focused than ever on their online presences as a result.

The scale of the shift has been spectacular. In 2017 alone, internet-only sales increased by 15.9%. By August 2018, 18.2% of the UK’s retails sales were made online.

And it’s only going to accelerate in the decade ahead. Analysts GlobalData expect online shopping to increase 30% by 2024, while Retail Economics foresee it at least doubling in the next ten years.

24/7 functionality for IGU manufacturers’

Fenestration, and construction more generally, is in many ways a totally different world. Industry has tended to lag behind retail and the high street when it comes to embracing the digital revolution.

But it’s inevitable that people who are used to purchasing more and more online in their personal lives are going to want and expect that in business too.

And that, combined with a long-term commitment to making IGU manufacturers’ lives as convenient as possible, is why we’ve launched Edgetech’s very first e-commerce platform.

With our quick and intuitive online ordering system, our customers can now place orders in minutes, wherever they are, and whenever suits them best.

Alongside that 24/7 functionality, it lets you make repeat orders with the click of a button and track your purchase from initial order to dispatch and delivery.

Quantity-based savings are applied automatically, and, for larger orders, you can upload directly from Excel.

Complementing our online ordering system, we’ve also brought in electronic invoicing and electronic delivery tracking to make dealing with us as straightforward as possible – and to help drastically reduce the amount of paper we use. As a business, Edgetech is firmly committed to sustainability – after all Super Spacer has helped make millions of buildings all round the world more thermally efficient – and we’re constantly looking for ways to reduce our ecological impact.

Edgetech Customer Fulfilment Team

With all that, our hope is to make our customers’ lives just that little bit easier. But while online is important, e-commerce isn’t something we’ve implemented in isolation. In fact, it’s part of a much bigger ongoing shift in how we operate at Edgetech.

Since 2016, we’ve been committed to putting the needs of our customers at the centre of everything we do. We’re examining every aspect of our business, and making radical changes to the way we work with one aim in mind – better meeting the needs of IGU manufacturers.

In the last twelve months, we’ve completely reorganised our admin and customer-facing teams to offer even better service.

All departments that are heavily involved with customers on a day-to-day basis have been merged to form a new Customer Fulfilment Team.

Our receipt of goods, customer service, production specialists and others are now based in the same office, allowing them to offer a much more agile, streamlined, joined-up service.

These reforms have had an immediately positive impact – shortly after they were implemented, we went two weeks without a single back order for the first time in more than twelve months!

Best-ever customer feedback

We’re also strongly focused on measuring customer service – and we’re delighted to say recent surveys have returned the most positive results we’ve ever recorded.

We use the Net Promoter Score system for gauging customer satisfaction. Each quarter, we select forty customers at random and ask them how likely they are to recommend us on a scale of one to ten.

By subtracting the number of Detractors (people who give us six out of ten or less) from the number of Promoters (nine out of ten or above), you’re left with a total Net Promoter Score, which is used to measure overall customer satisfaction.

Our NPS scores have been steadily climbing over the last year – from 47 in July 2018 to 62 in November 2018 (a score of 50 is regarded as excellent).

In Q1 of last year, however, the company achieved 94 – the best result in Edgetech’s history, and probably one of the best NPS scores ever recorded!

That tells us we’re going in the right direction – but we’re not complacent. Whether it’s online or in person, we’ll continue striving to put customers at the centre until we can say with confidence that we’re the most customer-focused business in our industry.

How does warm-edge perform in extreme temperatures?

Windows are everywhere. You find them in every climate, on every continent on earth – and if you want to make IGUs (Insulating Glass Units) that can withstand whatever nature throws at them, the spacers you use need to be exceptional.

Thankfully, time and time again, warm-edge spacers have demonstrated outstanding performance, even in extreme temperatures.

Take our tried-and-tested Super Spacer, for example – currently celebrating thirty years of active service.

Subject to rigorous performance testing, Super Spacer has been shown to excel in temperatures from -40 to 85 degrees Celsius.

To put that into perspective: -40°c is a winter’s day in Antarctica. The highest temperature ever recorded – in Death Valley, California, back in 1913, was 56.7°c.

In other words, whether it’s the desert, the South Pole, or anywhere in between, Super Spacer is up to the task.

The Opus, Dubai – temperatures up to 49°c

One of the most spectacular projects to use Super Spacer happens to be in one of the hottest cities in the world – Dubai, where summer temperatures have been known to reach a roasting 49°c.The Opus Super Spacer Project

The Opus is a 21-storey tower, designed by celebrated Iraqi architect Zaha Hadid, that pushes physical and technological boundaries to achieve its extraordinary melting ice-cube shape.

It’s got a 6,000 square-metre flowing glass façade, and its central ‘void’ section consists of 4,554 irregularly-shaped IGUs, the vast majority of which were completely unique.

And if all that wasn’t a big enough challenge for its designers, they had the often intense heat to contend with.

In hot climates, a warm-edge spacer has to work particularly hard to hermetically seal the space between the panes. The constant expanding and contracting of the glass as temperatures rise and fall create constant force.

That means only a spacer as strong and reliable as Super Spacer was up to the task.

Gostiny Dvor, Moscow – temperatures as low as -42°c


And at the other end of the spectrum, Super Spacer played a critical role in the installation of a breath-taking glass roof on a historic shopping complex in chilly Moscow.

At the time it was built, it was the largest self-supporting glass roof in Europe – and had been ingeniously designed to cope with the Russian capital’s heavy winter snowfall.

The roof’s glass panels radiate heat – up to 65°c if necessary – allowing them to melt the snow!

Super Spacer’s flexible design was crucial to making this complex process work. Its shape-memory means that even when subject to the weight of heavy snow, or the heat produced to melt that snow, an IGU made with Super Spacer always returns to its original shape when those forces decrease.
