The Dow GREAT STUFF™ Window and Door Insulating Foam Sealant is built to fill and seal gaps around window and door rough openings without distorting their frames.

Build

Dispense in any direction by using the provided straw that will help to direct the foam into the gaps and cracks you want to fill. 

This foam gently and minimally expands to take on the shape of the door or window jamb to create a water-resistant, weathertight, and airtight seal.

The product is trimmable after 60 minutes with a serrated blade or it can be pushed back into the gaps. It can also be sanded, stained or painted.

The surface of this foam can discolor when exposed to sunlight so it is recommended to paint it if this makes a difference to the appearance of the final finished project.

One 12 oz can =  4-6 common-sized windows!

(36" x 60", 3/8" wide gap @ 1" deep)

Safety

Wear eye protection, gloves and protect the area from the excess product.

Uncured foam can be cleaned with acetone or GREAT STUFF PRO Cleaner for best results! Cured foam on hands or surfaces must be removed mechanically or allowed to wear off.

Keep ignition sources away from this foam and use them in well-ventilated areas.
