Get Foam Insulation Certificate 2013-2024

Spray foam can be either open cell or closed cell foam insulation. While both materials create an air seal, there are some differences between them that can make a difference for your project.

Sucraseal has an R-value of 3.7 per inch, which is higher than all other types of insulation. This high R-value means that Sucraseal is very effective at preventing heat loss.

The answer is that it depends on the style you use. For closed cell spray foam, you'll want to make sure that your foam is 2-3 inches thick on the walls and 4-5 inches thick on the roof deck. For open-cell foam, the same thickness is needed for the walls, but the roof deck should be sprayed to be 6-10 inches thick.

There are three different levels of density one can choose from when it comes to spray foam insulation—high-density spray foam insulation, medium-density spray foam insulation, and low-density spray foam insulation. Each different spray foam density is designed for a particular task and offers unique advantages.

Ultimately, closed-cell spray foam is largely the better choice. It's physically stronger and does a better job of insulating a space. It also creates an effective vapor barrier, meaning the homeowner doesn't have to apply one themselves after the foam dries.

Open cell spray foam insulation is R-3.6 to R-3.9 per inch. This R-Value is normal for open cell spray foam. Closed cell spray foam insulation is R-6 to R-7 per inch.

How much R-value does spray polyurethane foam provide? Spray polyurethane foam has an average R-value of 6.5 per inch of thickness. If you 3 inches of spray foam on a roof, it will gain an R-value of approximately 19.5 (6.5 x 3).

Closed cell spray foam has an R-value of R-7 per inch. In comparison, open cell spray foam has an R-value of R-3.8 per inch.
