Where can I find out about standards of materials in double glazing? I recently had a large window fitted (about 1.2m x 1.2m) and I'm concerned I can see stress lines (the rainbow-like patterns) in it when I look from a certain angle and that it hasn't been made with the correct quality glass. How can I find out for sure?

It's made of toughened glass and *SHOULD* have a British Standards number engraved into it when it was made. This is usually in one corner (but could be either on the inside or outside). The Glass and Glazing Federation
Check out the article about "Brewsters Fringe" at the following link
ps: 1.2 x 1.2 is a SMALL window not a large one.

Well, it's all relative I guess, but I don't think that 4 foot square is a small window for a house
Like 4 feet tall is a short American or a tall Pygmy?
1.2sq m. is a moderate kitchen window in England (or a shop-front in Armley).HomeOwnersHub website is not affiliated with any of the manufacturers or service providers discussed here. All logos and trade names are the property of their respective owners.
