5 Things to Know about Foam Insulation 5 Things to Know about Foam Insulation

Here are 5 important things to know about spray foam insulation.

1- Application

This foam is sprayed with special equipment that is typically operated by professionals and is best used for special applications such as filling, insulating, and sealing cavities in walls and around electrical outlets.

2 - Properties

Spray foam is especially useful in situations where you want to prevent your insulation from settling, shrinking, or sagging after it has been installed.

3 - Energy

In general, sprayed foam has a higher per-inch R-factor rating than other insulation such as fiberglass batts, which means it holds in more heat.

4 - Cost

Foam insulation by itself is more expensive than other forms of insulation, but it is less expense overall because installing it is a one-step process that eliminates the need for caulking, vapor barriers, and the use of specialized construction contractors.

5 - Product Types

Spray foam insulation is available in 2 different types: closed cell, or polyurethane, which offers a higher R-value, and open cell isocyanurate. Both are applied in liquid form and contain a foaming agent, which causes the liquid to expand.
