Review on Frost King C21CP Contractor 🥶 Diameter: A Reliable Solution for Efficient Insulation by Darryl Blumenthal

This foam sealant is great for gaps around seldom used doors - we have a deck door that is seldom used but has some gaps. I can patch the cracks for winter and leave it securely in place, and when summer comes and I want the door to open so some of the air in the foam just comes out. On the other hand, for gaps around windows or in walls. If you press it down firmly with a spatula or butter knife, I expect it will stay secure for decades.
