GREAT STUFF Gaps & Cracks is a polyurethane-based insulating foam sealant that fills, air-seals and insulates small gaps (less than 1 inch) inside or out. But you probably guessed as much from the name. What you might not have guessed is how easy it is to use (thanks to the straw applicator) or how it expands to take the shape of cracks and voids to form a durable, airtight, and water-resistant bond that eliminates unwanted airflow and helps reduce condensation.

Why Use Great Stuff Pro Gaps and Cracks

HIGH HEATING & COOLING BILLS Air leakage through holes, gaps, and cracks is the single biggest cause of home heating and cooling loss. It actually accounts for 30 to 50 percent of the energy used in most homes. If you took all the gaps and cracks around window and door frames, electrical outlets, plumbing lines, under the siding, in the basement, and in many other places, they'd add up to a space the size of a standard window. So essentially, you're heating and cooling your house year-round with a window open. We suggest closing the window. Use GREAT STUFF to fill in those gaps and cracks, then sit back and start counting the money you're saving. Want to see just how much money you can save? Click Great Stauff Pro Energy Savings.
It's too cold. Now it's too hot. This is an annoying problem that's easy to fix and pretty cheap to boot. It's usually just a question of air leakage or insufficient insulation. So install proper insulation and use GREAT STUFF to seal and fill all the gaps and cracks that are letting in air. Try these less expensive options before checking out or replacing your costly HVAC distribution system.
Mold and mildew problems can be health hazards. Some mold and mildew problems occur because warm moisture travels through gaps and then condenses on cold surfaces. When left unchecked, it can cause wood to rot and may lead to respiratory problems for people with mold sensitivities and allergies. In short, it's a serious problem. Air-sealing and insulating all gaps between the attic and the living quarters with GREAT STUFF helps prevent mold growth and the potential for health hazards.
