Making my own Window exterior insulation panel insert
There are small recesses on the exterior of the wood window frames where I want to insert permanent glass/plexiglass cover for insulation. I need advice on what framing I can use, similar to a poster frame trim where I can install it around the glass, then slide it into the window recess. I’d like to use an aluminum trim that is fairly narrow that would look good. I find framing trim that has slots I can slide the glass into, but what I’m finding is too thick. I only have about quarter inch I can insert to. Any advise?
