5 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 window frame to bow and hinder operation.

A.Apply insulating foam sealant. From the interior, insert the nozzle of the applicator approximately 1" deep into the space between the window 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 interior surface of shims

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.

B.Check the 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 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.

Interior Finish or Trim: The space between the new window and the existing window’s frame will need to be covered with trim. There are many ways to accomplish this and each case can be unique. How this is done will be the decision of the homeowner or window installer. A few possibilities include using cove, quarter round, or a stop moulding.

6 EXTERIOR SEAL

A. Insert backer rod into the space around

6A

the window. This should provide at least

 

3/8" clearance between the backer rod

 

and the exterior face of the window.

 

Note: Backer rod adds shape and depth

 

for the sealant line.

 

B. Place a bead of sealant at the jambs and

6B

head between the existing window frame

 

and the replacement window frame.

C. Begin the sill sealant bead 1/2" from one jamb, running it across the sill and stopping 1/2" from the opposite jamb. This 1/2" sealant gap on each side of the sill allows for incidental water drainage.

D.Shape, tool, and clean excess sealant. When finished, the sealant should be the shape of an hourglass.

Note: This method creates a more flexible sealant line capable of expanding and contracting.
