Spray Foam 101: Open vs. Closed Cell Foam Insulation

If you’re considering insulating your home with spray foam, it’s important to understand some of the basic differences between the types of spray foam insulation that are available for you to choose from. When it comes to residential foam insulation like Icynene, you have two primary choices: closed cell and open cell spray foam.

The first option, closed cell spray foam insulation, is a medium density rigid spray foam. It’s ideal for small spaces that still need a high, consistent level of insulation, due to its higher R value per inch than open cell spray foam. Closed cell foam can also assist at rejecting bulk water penetration, making it an ideal consideration for areas of your home that are more humid or prone to flooding such as basements.

Also available is  open cell spray foam insulation, which has a sponge-like, flexible texture because of its low density, even after curing. This helps it retain its insulation properties all year round and makes it particularly good at helping to dampen sounds. Open cell foam is generally used in residential construction because it’s ideal for filling gaps in the walls. It is also an air barrier, which means it can help reduce the amount of air that escapes from your home.
