Closed Cell Foam creates a very dense and hard finish that has more mass than Open Cell Foam. Yet, it still keeps the moisture and air out. It's an excellent barrier.
Expanding foam has thousands of tiny cells. They're still there after the foam is expanded and, combined with the strong adhesive qualities of the material, it makes an ideal insulation solution for just about any situation.
These foams have a lot of density ranges from 1.7 lb/ft3 to 2 lb/ft3. They also make the structure stronger. In fact, the weight-to-strength ratio is better for these foams so they can handle heavier loads.
Your home can be protected from strong winds and your roof can support more weight, in both cases, it's thanks to the trusted protection that watertight seals provide.

Closed-cell foam is a solid choice for insulation and fares better than other products. It has an R-value range of up to 7/inch which is double what some insulations provide. Its quality surpasses 40% of open-cell foam products.
With its good water resistance, this product is perfect for insulation in limited areas like standards walls & roofs. It can even be used around areas that come into contact with water.
Smaller jobs can be helped by ordering a small can of closed-cell foam and applying it to areas and gaps that need filling. For instance, you might want to use it on cans lights and empty spaces surrounding the cans.
A second option is what is called kits. These typically come with a 220V air compressor, welded canister, hose, and gun. They work best for rim joists or small jobs like ducting.
The first applications are one-part formulations. For the bigger jobs, you need two parts. For these cases, it's best to have a truck mix the foam and apply it with a hose.
