They are acrylic wrapped vinyl if you want to call them that. The wrap is is heat/chemically fused to the frame, not something you can peel off. The windows are from All Weather Windows, which is the company that Integrity deals with, so I didn't really have a choice, but so far happy with the look and feel. My patio door is the same way, black inside and out acrylic wrapped vinyl, from same company.This quote is hidden because you are ignoring this member. Show Quote
Since I had to look this up, decided to check on the window coating for completion, and it's HS3 glass, which is Triple pane, two Low-E coatings, Argon with an R value of 7.5.
