Tomas -- I am so sorry that I did not see this and reply right away instead of years later. The windows are Canadian and I will get the exact name and get back to you. You can respond directly to my google account -- way better chance of my seeing it.
Tomas -- Thermotech -- fiberglass -- same coefficient of expansion as glass.
