Spray foam insulation is a type of plastic foam that can be applied to walls, roofs, and other areas to insulate and reduce air infiltration. It is sprayed as a liquid and then expands to fill the space. The spray is usually composed of two components, isocyanate and polyol resin. These chemicals are mixed together at the tip of a gun and then sprayed onto the area to be insulated.

When professionally installed, this type of insulation can provide exceptional coverage and precision. Professionals use specialized rigs that monitor the foam’s temperature and consistency, ensuring consistent results and excellent energy efficiency. This may be a factor in the higher cost of spray foam compared to DIY options, but for larger projects or for precise results, professional application is often the best option.

Before spraying the foam, a crew will carefully prep the area. This might involve removing existing insulation or building materials in an attic, crawl space, or rim joist in an existing home, or removing construction material and drywall in newer homes or pole barns. They will also calculate the square footage needed, based on the area to be insulated. Walls typically have studs every 16”, so multiply that by the number of walls to determine the board footage required.

Closed-cell spray foam is versatile enough to be used in any situation where it can help improve a building’s thermal performance. It acts as both insulation and an air sealant, closing nooks and crannies that let hot or cold air escape a house and increase monthly energy bills. It also helps to prevent moisture intrusion, which can cause mold and other damage.
