Coventry University – Thermal insulation tests

In April 2014 we received confirmation that Extraglaze is a scientifically proven thermal insulation solution that beats the competition.

The university's Sustainable Buildings Future project used their Environmental Chamber to compare Extraglaze with a top of the range aluminium-framed glass secondary glazing system...
...Extraglaze came out the clear leader.

  • When tested on a single glazed sash window the Extraglaze U-value, used to compare insulation values, proved 11% better (2.28W/m²) than the alternative product.

  • We already knew that Extraglaze would be a better solution to deal with condensation, and the tests confirmed it. In a humid room test (60%RH), with below zero temperatures outside (-5 and -10ºC) Extraglaze was an impressive 78% better.

bre logo BRE – Sound insulation tests
In July 2013 a large timber framed window (1.3m² of visible glass) was installed in the Building Research Establishment's (BRE) Horizontal Transmission Suite, and tested against an aluminium framed glass secondary glazing system. A wide range of tests were made, to see how secondary glazing could not only improve a single glazed window but even a double glazed window.

To summarise the results both systems were rated "good" as a sound insulator for noise problems. We learned in particular that smaller panels do best, being more rigid, and the larger the gap, between the original window glass and the Extraglaze, the better. What surprised us most was that it didn't seem to make much difference whether the original window was double glazed or single glazed.

Proof in practice
In January 2014 Extraglaze was installed onto brand new triple glazed UPVC bay windows in a home by a main road. The triple glazing had been installed to cut the road noise but had proven ineffective. However, with the addition of Extraglaze road noise was almost completely eliminated.

And news from customers...

We have an ever increasing number of testimonies from our customers, which can be seen in the testimonials section. It is clear that our customers enjoy their homes much more now than they did before Extraglaze was installed, being much warmer and much quieter.
