Flashing an existing window


Hello,

I am working on vinyl siding my house. I have taken off the old siding, installed foam board and have wrapped the house in Tyvek. My concern is at the windows. Because I windows were installed before I wrapped the house, how do I make sure that the windows are properly sealed to make sure water does not get behind the Tyvek, foam board and on to the sheathing?

Thanks,

You could fold the Tyvek into the seams and fill the gaps with expanding foam insulation. That stuff sticks to EVERYTHING When its dry, cut the excess with a knife before you install the j-mold and drip cap.

PS: Use the foam sparingly...too much could expand enough to buckle walls and distort window frames.

Will you have access to the window flanges? If so cover them with a rubber membrane product like Grace vycor.
At the top of the window install a rain cap (using caulk) first and vycor over that.

When I removed the siding there was no window flange. The windows are replacment windows.

No, the windows have wood wood. I wasn't going to wrap them in aluminum.

There is a plastic membrane that extends to and attaches to the sheathing between the head/side jams and the window trim. The windows are kind of "flashed" with this? It is under both the foam board and tyvek wrap.
