Spray foam insulation has been used in residential and commercial construction for decades. There are two forms of spray foam used: open-cell and closed-cell. While open-cell spray foam is ordinarily limited to interior use, closed-cell options are much more versatile. Use the following guide to learn more about this material and how it can help your property.

What Is It?

Closed-cell spray foam is a rigid, medium-density material made from polyisocyanurate and resin. The two liquids are kept separate until they’re combined and applied at the job site. A qualified, licensed spray foam installer uses a heated hose and spray gun to fill in cavities with the foam, which expands and hardens when it meets air.  

Compared to open-cell foam, closed-cell is harder and denser. It doesn’t allow moisture to permeate the material.

Common Uses

Closed-cell spray foam is more common in commercial buildings because of its exterior capabilities. However, it can also be used as interior insulation in residential walls, roof decks, and crawlspaces.

It provides continuous insulation ideal for the exposed materials in pole barns and commercial roofing. It has a higher R-value than open-cell spray foam. It also rejects water, making it flood-resistant.

Benefits

Closed-cell spray foam insulation can improve energy efficiency by preventing air leaks and maintaining even temperatures. It can also be applied at lower temperatures than open-cell foam, making it applicable year-round.

Because of its density, it also offers racking strength to walls and improves impact resistance to structures. Both open- and closed-cell spray foam are useful for adding layers of insulation to existing structures.
