A.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. 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: DO NOT place any foam between jamb extensions and the rough opening.
B.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.
C.Add a sealant bead across the inner sill and 6” up each jamb between the frame and rough opening.
