Spray Foam Insulation Guide

Foam insulation spray is a dual-purpose product that air seals and insulates at the same time. Foam expands as it is applied and fills the cavity completely to stop air leaks while keeping costs for energy at a minimum. Spray foam insulation decreases the heat transfer between different rooms of the house. In addition, it helps seal air leaks to stop the conditioned air inside from escape.

Types of Spray Foam Insulation

Open cell foam serves as an insulator and a barrier. The R-value typical of open-cell foam insulation ranges from 3.7 for every inch. Other characteristics in open cell insulation are the ability to withstand vapor, allowing for seasonal changes, and is it is not a food source for mold, it dampens sound and is excellent to use for insulation in attics.

Closing cell foam insulation acts as an insulator and a barrier. The bubbles' cells remain in place (closed) making the product pliable. The closed cell structure and the increased density result in an R-value that is higher than free cell foam. This may help build resilience during high winds.

Why is it important?

Air leaks are present within the building envelope, which is the outermost part of the home, including rooflines and walls. Air leaks can occur via entry points in places like recessed lighting pipes, electric wiring, chimneys, attic hatches/doors, and chimneys. If air leaks are closed then the conditioned air remains inside your home. This means that your HVAC system not working as hard which means that money stays in your pocket.

When you install Spray foam insulation space is sealed and insulated in one go, providing an insulation barrier as well as sealing the penetration points. After one application to spray foam you can be certain that air leaks will be completely closed.
