Performance of Alpen Windows
In another question on the site someone asked about Alpen windows and in looking at the Alpen site they mention using thin glass instead of a suspended film for energy efficiency.
There’s also this video from AE Building Systems discussing the different types of Alpen glass.
Has anyone used these units and if so, how did they perform (apparently they can hit an R(.5)? Were there any issues with handling or installing them?
