How to Fill Gaps and Cracks with Foam Sealant

While this kind of foam can work just fine in these instances, high-pressure foam is not a good idea. Look for low to medium expansion foam only when closing gaps and cracks around doors and windows. High-pressure foam is often strong enough to push a frame out of alignment, making a window difficult to open or causing a door to stick.
