4 INTERIOR SEAL

Caution: Ensure use of low pressure polyurethane window and door insulating foams and

strictly follow the foam manufacturer’s recommendations for application. Use of high pressure
foams or improper application of the foam may cause the window
frame to bow and hinder operation.	4A

A.Apply insulating foam sealant. From the interior, insert the nozzle of the applicator approximately 1" deep into the space between the window and the rough opening and apply a 1" deep bead of foam.

This will allow room for expansion of the foam and will minimize squeeze out. If using foam other than Great Stuff ™ Window and Door Insulation Foam Sealant by the Dow Chemical Company, allow the foam to dry completely (usually 8 to 24 hours) before proceeding to the next step.

Note: DO NOT completely fill the space from the back of the fin to the interior face of the opening.

B.Check window operation (vent units only) by opening and closing the window.

Note: If the window does not operate correctly, check to make sure it is still plumb, level, square and that the sides are not bowed. If adjustments are required, remove the foam with a serrated knife. Adjust the shims, and reapply the insulating foam sealant.
