316 Insulation is an expanding insulation product that provides excellent coverage, filling in all nooks and crannies of walls, ceilings, slabs and other surfaces. It consists of two liquid chemicals that react on-site when sprayed, creating a high-density, airtight seal. This reduces drafts and helps control humidity levels, both of which are important factors in preventing mold growth.

Spray Foam Insulation vs. Traditional Insulation: What You Need to Know

The closed-cell type of spray foam insulation offers superior R-value per inch as well as a moisture barrier. It also helps reduce the transfer of heat from outside to inside the home. In addition to this, it can help improve indoor air quality by reducing dust mites, mildew and other allergens. It can also be used as a sound-deadening and fire-rated insulation.

Unlike fiberglass batts, which are made of glass fibers or polyethylene, spray foam insulation is formed on-site using a special spray gun and two components of liquid chemicals. The “A” side is typically a blend of isocyanate and polymeric methylene diphenyl diisocyanate (pMDI). The “B” side is usually a mixture of polyols, catalysts, blowing agent, flame retardant, and surfactants. When the “A” and “B” sides are combined, they create a polyurethane foam that expands up to 100x its liquid volume.

While DIY kits are available for homeowners who wish to do their own installation, it is recommended that a professional technician install this type of insulation. This is because spray foam insulation produces large amounts of volatile organic compounds (VOCs) that off-gas during application and the curing process, and it is a good idea to have occupants of a home stay away from the area until it’s been fully cured.
