Whether or not you wrap the house, it’s important to flash around the window and door openings. Especially with windows, proper flashing can prevent the water that runs down both sides of the window from entering the wall cavity through the sill area. To flash window and door openings, I generally use б-in.- to 8-in.-wide strips of felt paper, installing the strips as shown in the illustration on the facing page. Don’t forget to install the top piece of flashing after the window has been set in its opening. If housewrap
is used, you can still install a top piece of flashing. Cut a horizontal slit in the house — wrap above the window, then slip the top edge of the top flashing piece into the slit.
