9INTERIOR 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.
A. Apply insulation foam. From the interior, insert the |
|
nozzle of the applicator approximately 1" deep into | 4A |
the space between the window and the rough opening | 9A |
| |
and apply a 1" deep bead of foam. This will allow |
|
room for expansion of the foam and will minimize |
|
squeeze out. If using insulating foam other than Great |
|
Stuff™ Window and Door Insulation Foam by the |
|
Dow Chemical Company, allow the foam to cure |
|
completely (usually 8 to 24 hours) before proceeding |
|
to the next step. |
|
Note: It may be necessary to squeeze the end of the tube with pliers to be able to insert into the space
between the new and existing window frame. DO NOT completely fill the space from the back of the backer rod to the interior face of the opening.
10 EXTERIOR SEAL
A.Insert backer rod into the space around the exterior of the window at the head and jambs, deep enough to provide at least a 1/2” clearance between the backer rod and the exterior face of the window.
Note: Backer rod adds shape and depth for the sealant line.
