opening and closing the window.
Note: If the window does not operate correctly,

and the jambs are not bowed. If adjustments are
required, remove the foam with a serrated knife.
Adjust the shims and reapply the insulating foam
sealant.

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.

to create a continuous seal. For windows with jamb
extensions installed, ensure the foam is placed between
the window frame and the rough opening, not between
the jamb extension and the rough opening. Follow
foam manufacturer's instructions.
