Window and Door Preparation
Preparing for Window Installation
STEP 1
After wrapping the structure and covering all rough openings. Cut a horizontal line across the top of
the window opening. The cut should not extend past the rough opening.
STEP 2
Start at the top center and make a vertical cut running two-thirds of the way down the opening.
STEP3
From that stopping point, cut diagonally to both lower left and right corners of the opening.
STEP 4
Pull each of the flaps tightly inside the rough opening and attach them to the frame with nails,
staples, or tape.
STEP 5
At the window header, make a 6” diagonal cut at a 45 degree angle on both corners. Fold the
material up exposing the sheathing. Now install the window or door according to the manufacturer
instructions. The final step is to flash all seams and flanges securely (refer to Typar® Flashing
instructions). Typar® flashing should also be installed in accordance with window manufacturer
instructions and according to the ASTM 2112 standard.
