What is spray foam insulation?

Spray foam insulation is a liquid foam that's sprayed into position and sets to form an insulating layer. It can be used to insulate your roof, loft, walls, floors and more. It's been in use for more than 30 years and has become increasingly popular, despite criticism, because it offers insulation and may also stop air leakage.

Two Types of Spray Foam Insulation

Open-Cell Spray Foam: This foam is more flexible and lets air move through it. It's lighter and cheaper, great for walls and attics.

Closed-Cell Spray Foam: This Closed-Cell Spray Foam foam is denser, offering better insulation and sealing. It's best for places needing strong thermal and moisture protection, like roofs and foundations.

Benefits Of Spray Foam Insulation

With some of the highest insulation R-values available, spray foam insulation can improve efficiency and comfort. Spray polyurethane foam (SPF) is a versatile insulation and sealant that can create a continuous air barrier on multiple surfaces in homes or buildings, including ceilings, walls and concrete slabs. Spray polyurethane foam is created by mixing two fast-reacting liquids, isocyanate and polyol resin, that expand to create foam when mixed.

Maximize Energy Efficiency

As much as 40% of a building's energy loss can be traced back to air leaks and infiltration. When gaps and cracks are left unsealed, your heating and cooling systems work harder — driving up utility costs unnecessarily. In fact, the U.S. Department of Energy reports that over half (56%) of a home's energy usage typically goes toward heating and cooling.

Spray foam insulation (SPF) offers a modern solution compared to traditional options like fiberglass or cellulose. It not only reduces heat transfer but also seals air leaks, forming a strong, continuous barrier. This helps block unwanted air movement, moisture, and even noise — improving both energy efficiency and indoor comfort.

Maximize Energy Efficiency

Spray polyurethane foam (SPF) expands upon application, filling gaps and cracks to create a consistent, airtight seal. By reducing air leakage in walls and roof spaces, homeowners can cut heating and cooling costs by up to 15%, according to the U.S. Department of Energy. SPF is especially effective in sealing common trouble spots for air infiltration, such as:
