Spray foam insulation has become a top choice of both homeowners and businesses for its incredible energy efficiency. Yet, many individuals are unaware that there are two types available: open cell and closed cell. If you're considering using foam insulation for your new build or renovation, here's a closer look at the difference between the two options.

A Guide to Open & Closed Spray Foam Insulation

What's the Difference?

Open cells are incredibly soft, lightweight, and flexible. They also expand to around three inches with one application. In contrast, closed cells are denser, so a single-coat only expands to about one-third of their open counterpart. While the quality usually results in the need for multiple coatings, it provides a thick, heavy-duty layer of protection.

What Are the Benefits of Each?

The high density of closed cells creates a powerful moisture barrier while also reinforcing the building materials. Open cell foam, on the other hand, can fit into incredibly small areas to ensure every centimeter is insulated. Additionally, the thick expandability of the open cells restricts noise transfer.

Which One Is Right for You?

Choosing a type of spray foam insulation is largely dependent on the project. Closed cell's water-blocking capabilities make it a prime choice for exterior wall insulation. It can also be installed at much lower temperatures than the alternative. To dampen noise indoors, open cell is typically used between floors and in interior walls of theater rooms or at-home recording studios. In some cases, both styles are used to ensure optimal coverage and protection.
