Types of Spray Foam Insulation

Open-cell insulation is softer and can easily conform to the shape of celling where it’s been sprayed. This is because it has a very high expansion rate, due to which it expands into and seals all the irregular and tiny spaces as well, which are hard to get. This is why even the corners and odd-shaped parts of the attic will be properly sealed and insulated. It is generally the lighter option of spray foam insulation.

Closed-cell spray foam insulation

Closed-cell insulation is also known as two-pound foam. It is a little more rigid and much denser than the open cell, it’s because of the lack of moisture and less expansion. Although closed-cell spray foam is more durable, it gets dry faster than open-cell spray foam. It has a longer lifespan than open-cell spray foam. Most of the builders prefer closed-cell insulation because it has a little higher R-value.
