Does anyone have an experience with Pella’s “Impervia” line of windows? They are made of a material they call Duracast. They are supposed to be nine times stronger than vinyl and twice as strong as aluminum. I like the idea of a dimensionally stable window. I’m thinking using these windows in a house in the desert southwest so something that can perform well in high heat would be great. I’m just wondering if anyone has an opinion on these windows or perhaps another window that would work well in that climate.

Thanks.
