Day Two Seal the Opening. - An innovative special flashing system was used to seal and protect the window from leaking for this particular project. See Resources, below, for more information on ProtectoWrap.
- Apply this double-sided adhesive along the surface of the window frame, starting along the top.
- Overlap the next strip at the corner (figure A), making sure there are no gaps, and press into place.
Expert Tip: This is a very sticky asphalt based product that will create a positive seal once the window goes in. It's pliable. - Lay pan flashing down on the sill using flashing tape. You can create this pan flashing with window tape. Start the flashing on the sill on one side of the window and extend it to the other side (figure B).
- Then make two cuts so you can fold the flashing over the top of the sill. The adhesive creates a watertight seal and helps protect the sill from condensation or leaks, which should prevent any future rotting.Note: The outside of the tape has a polyethylene film that helps keep the water out.
- Add a second layer of flashing over the first layer. Cut the outside edges so this layer can lay flat against the sheathing.
Installing the Window - Dry fit the window first to see if you need to make any adjustments. For this particular project, the window was a little low, so Ryan used two small shims (figure C) in each corner to raise the window to the proper height.
Tip: Make sure the unit is centered left and right so you can put insulation on both sides. Safety Tip: When installing a window this heavy, safety is important. Don't walk away from the window until it is secured. - Remove the window, exposing the sticky tape.
- While someone holds the window in place for you, drive a couple of 3" screws to hold the unit temporarily until you shim it in place.
- Check the level.
- While someone continues to secure the window, drive a 4" lag screw in through the center top of the window frame (figure D).
- Adjust the plumb by drilling in screws at the top and bottom and then add the shims to hold everything into place.
- Level and plum the window.
- Put two lag bolts in through the top frame.
Sealing the Window - Put flashing tape up and put on the drip cap (figure E).
- Put flashing along the bottom and sides. Lay the wrap so that it covers the window about a quarter of an inch. You do not want the flash to show above the trim or the siding.
- Put the outside wall back together.
- Drywall the return on the inside by cutting the drywall pieces and then putting them into place (figure F).
- Assemble the drywall corner bead.
- Put on joint compound.
