Hello! Building our home with our own hands at 7400 ft in a special wind zone in Wyoming. I’ve got lots of questions for you, as I’m gathering loads of helpful info from your site, but I’ll start here with windows. Aluminum windows are used in this region and in other cold/extreme environments for commercial buildings, many of which are concerned with their thermal envelope. And yet, aluminum, thanks to its high thermal conductivity, is not recommended for residential windows – even thermally broken ones. Why? Doesn’t the conductivity issue get entirely resolved via the thermal break? Please help? B/c otherwise, I am in LOVE with the durability & the relatively low expansion coefficient of aluminum vs other materials. Fiberglass’ thermal expansion coefficient is the same as glass – HOWEVER, Fiberglass windows are not/cannot be 100% fiberglass – they are a composite of fiberglass & some kind of polymer. So, the expansion coefficient becomes hazy. Aluminum’s is simply twice that of glass… Thank you for any insights you can provide.
