Spray foam insulation is a popular green building material because it insulates better than fiberglass batts and cellulose, leading to major heating and cooling cost savings for homeowners. While spray foam is available in DIY kits for a do-it-yourself installation, a professional contractor is the best choice for larger projects with complex structures, and for areas that require accurate thermal performance.

The attic insulation is sprayed directly onto walls, roofs, and attics in homes, commercial buildings, and pole barns. It fills in every nook and cranny and blocks conductive, radiant and convective heat transfer. Unlike traditional insulation, it also provides moisture protection and prevents the buildup of mold, mildew, and rot.

There are two types of spray polyurethane foam: open cell and closed cell. Open cell is less expensive and offers an R-value of 3.2-3.8 per inch, meaning it can add up to around R-13 in a 2×4 wall or R-19 in a 2×6 wall. However, it can absorb moisture and vapor that could affect the structure of the home, and will need to be covered with a vapor barrier after installation.

Closed-cell spray foam is more expensive, but it creates an air and vapor barrier in one, so homeowners don’t need to install their own vapor barrier after the insulation dries. It is also physically stronger and can improve structural integrity of a home. Meritage uses a non-toxic soy-based closed-cell spray foam, called HEATLOK SOY®, that recycles plastic waste into a rigid spray polyurethane insulation and air barrier.
