INTERIOR SEAL
Caution: Ensure use of low pressure polyurethane window
and door insulating foam 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.

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.

SEALING THE WINDOW TO THE EXTERIOR WALL CLADDING
When applying siding, brick veneer or other exterior finish material, leave adequate space
between the window frame and the material for sealant. Refer to the illustration that
corresponds to your finish material.
Note: The sealant details shown are standard recommendations from the sealant industry.
Contact your sealant supplier for recommendations and instructions for these and any
other applications.
