Window Framing, and Water Proofing

This is a remodel, to accommodate the thickness of the new window we needed to extend the forming out from the building. We wanted the framing to be protected from the weather so we used zip system stretch tape, attaching it from the inside of the opening and stretching it around onto the plywood with no gaps, so when water eventually gets between the window and the framing it will hit the tape and drain out instead of leaking into the wood and rotting.
