New vinyl replacement windows – gap between framing & window jamb, air seal?
I’m finally getting around to replacing some rotting wooden windows with new vinyl replacements. I took off a piece of the brick mold today and I’m not surprised to find a fairly large 1/2″ gap between the old window jamb and the rough framing. There’s some random batt insulation stuffed in parts of the holes, but not all of them.
* First of all, is this flashed right? There’s some sort of vinyl-like house wrap going around the rough framing member. I know nothing about flashing really, especially on brick veneer homes. This home was built in the fall of 1999, the walls have no weep holes (but it’s a peer and curtain wall foundation – I think you don’t need them for that), and I’m in Eastern North Carolina. The caulk around the brick mold split over time and water was getting behind here, so there is some rot on the outer OSB under the black wrap, but nothing too bad I don’t think.
* Spray foam – I have a feeling I should try to seal this gap with window and door great stuff, but should I? Will it interfere with the vinyl-like wrap?
Photos below show the brick mold removed. The 1 1/2″ wide stop is still on in the photos. I’m replacing all the stops, brick mold, and trim with the PVC kind. Thanks Martin & anyone else for your help!
