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 door frame to
bow and hinder operation.
A. Add a sealant bead across the inner sill and 6" up
each jamb between the frame and rough opening.
B. Apply insulating foam sealant. From the interior,
insert the nozzle of the applicator into the space
between the door and the rough opening
approximately 1" past the edge of the frame
(and past the jamb extensions) 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 the shims to create a continuous seal.
Follow foam manufacturer's instructions.
Note: DO NOT place any foam between jamb
extensions and the rough opening.
C. 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.
