Product : Just the ticket. Colour and wood matching are a super feature.Helen Bostock1 month ago
Delivery was as stated, and a phone call the day before to confirm it. Product well packaged. My only criticism would be that installation instructions were not included, although the website indicated that they would be. I had installed them before, but several years ago, and a reminder...Please accept our apologies for the omission. It is standard to make sure you receive these via our email at the time of dispatch. They are also available to view when you sign in to our web site: they are found under "My Extraglaze".Read more...

We needed to use an adhesive not prone to the problems we'd seen in competing products.
We found one we preferred and tested it.
We had fun proving just how strong it really is. It's the same adhesive used to fix Extraglaze Secondary Glazing panels to window frames. The amount of adhesive used in this test is the same as we would put around the edges of a panel of size 1.2m wide by 1.2m tall.
