Extraglaze was installed as part of a real life case study, in a real home, and the results measured and reported by Veritherm.co.uk
We are grateful to Veritherm for allowing us to publish this report here, which they did independently – it was not commissioned by Extraglaze.
Veritherm's case study is shown in the document below. The references to our secondary glazing are found using the highlights. In summary the case study applied numerous measures to insulate the property, and while the challenge of fully insulating it like a modern build proved unachievable, the one that made the most measurable improvement, out of all of them, was the Extraglaze secondary glazing.
In the last three pages the case study has estimated the quantifiable cost savings and payback timescales for this, reasonably small property. It goes on to expect better-than-estimated results, which will be borne out and reported on in the future.
