How to Install Awning Windows the Easy Way

1. Measure the height and width of your opening and purchase an awning window that fits in the opening with about a 1/2 inch to spare all the way around.
2. Cut strips of roofing felt about 8 inches wide and cover the inside of the framed opening with the felt allowing the excess to lay flat against the exterior of your home. You can attach the felt with staples or felt nails.
3. Install a bead of caulk around the outside perimeter of the opening where the window flange will rest against the wall.
4. Set the window in place, and center it in the opening using cedar shims to hold it in its final location.
5. Nail or screw one of the top corners through the nailing holes in the flange.
6. Use a level to plumb and level the window adjusting shims as needed, and nail or screw the other three corners.
7. Check the window for proper operation; it should open and close easily, lock securely, and the sash should have the same margin around around the frame.
8. Finish nailing or screwing the awning window in place.
9. The nailing flange should be holding the previously installed roofing felt flat against the exterior wall surface; apply 8 to 12 inch wide rubber waterproofing membrane over the flange and felt on all sides of the window.
