Green Homes Grant

(announced 7th July)

Important update for October 2020: Extraglaze has given great consideration to the Green Homes Grant, and has declined to take part. Having investigated the grant in some detail the process of joining the scheme is far beyond our capacity, particularly during the busiest time in our calendar year. It looks like it would take several months of intensive effort to achieve, and much of it dependent on others, with processes and approvals outside our control timewise. This level of uncertainty means the time in which to complete work (before March 2021) may turn out to be impractical, possibly negative.


The Green Homes Grant voucher scheme was outlined by the Chancellor to fund and help bring work to UK businesses that have suffered because of earlier lock down measures. It will help home owners insulate their homes and improve their green credentials, in a very short period until the end of March 2021.

Thermal insulation tests at Coventry University

  coventry university logo


 

In April 2014 we received confirmation that Extraglaze is a scientifically proven thermal insulation solution that beats a typical aluminium framed alternative.

The university's Sustainable Buildings Future Project used their Environmental Chamber to compare Extraglaze with an aluminium-framed, glass-pane secondary glazing system...
...Extraglaze came out the clear leader.

arrowpichigh tinyWith both systems tested on a single glazed sash window the U-value for Extraglaze proved 11% better (2.28W/m²) than the alternative product.

arrowpichigh tinyWe 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.




Extraglaze put to the test in the Environmental Chamber


Sound insulation tests at the Building Research Establishment

bre logo

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 fabulous testimonies from our customers, which can be seen in the many reviews they have left on Feefo. 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.

If you are an engineer or architect please contact us to discuss the results of tests in more detail.
