Caution: Ensure use of low pressure polyurethane window and door installation 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 door to bow and hinder operation.
A.Apply insulating foam. From the interior, insert the nozzle of the applicator approximately 1" deep into the space between the door 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. Apply sealant across the interior surface of shims to create a continuous seal. For doors with jamb extensions installed, ensure the foam is placed between the door frame and the rough opening, not between the jamb extension and the rough opening. Follow foam manufacturer's instructions.
Note: It may be necessary to squeeze the end of the tube with pliers to insert it into the space between the door frame and the rough opening. DO NOT completely fill the space from the back of the brickmould to the interior face of the opening.

B.Check the door operation by opening and closing the door.
Note: If the door 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.
C.Add a sealant bead across the inner sill and 6" up each jamb between the frame and rough opening.
