I’m looking to replace some awning window sashes with replacement units. I like everything I read here at BT about Integrity but they seem to be made only for new construction. I’m thinking maybe I could cut off the flange and insert them into the opening, like one would do with replacement windows.
I’m also open to other suggestions. The owners want a maintenance free, tan color exterior, fiberglass or aluminum.
They want wood for the interior, which is to be painted.
Any and all feedback appreciated.
