How Spray Foam Insulation Works

spray foam insulation is a liquid that rapidly expands in place, filling the cracks and crevices between walls and other surfaces. It can be sprayed into new construction or a home’s attic and is often used in conjunction with other insulation materials such as fiberglass batts. It’s typically installed by a licensed professional, since it requires working with hazardous chemicals that must be handled properly.

The first step in the process is to blend the chemical components that will create the spray polyurethane insulation. This is done using a machine called the Blendometer. After the liquid chemicals are blended, they pass through a spray gun and become “atomized” (the chemical molecules are reduced to very small particles). Once they enter a space, they will react with each other to form the spray foam insulation. The chemical reaction that occurs is an exothermic process, which generates heat as a byproduct. The end result is a solid, closed-cell insulation that provides superior energy efficiency and structural strength.

There are two types of spray foam insulation: open and closed cell. Open-cell spray foam is softer and more flexible because it’s cells are left intentionally open rather than completely encapsulated. It’s commonly used during the rough-in stage of construction to seal voids around plumbing and electrical wiring. It’s also a great choice for retrofit applications such as insulating walls, re-insulating basements and attics, or converting garages into living spaces.

Many states, including Vermont, offer rebates for green weatherization measures, such as installing spray foam. These rebates can help offset the cost of the installation and reduce homeowners’ energy bills.
