Spray foam insulation is one of the most effective building materials on the market for weatherizing buildings. It acts as both insulation and an air seal, closing the nooks and crannies that let air escape and raise energy bills. It also prevents moisture, which can damage drywall and encourage mold and mildew growth.

It’s made from polyurethane, a combination of two resins that create a foam when combined. It has long been criticized for being toxic, particularly while it’s still curing. During this period, it releases a gas that causes blurred vision and trouble breathing. It’s important to wear full face and respiratory protection when applying it. It’s also a powerful eye irritant and can cause rashes on the skin.

Practical Applications of Spray Foam Insulation in Home Renovations

The chemistry behind this insulation is complex, but the main point is that it’s a powerful barrier that restricts heat flow in or out of the space. Its ability to seal nooks and crannies also helps it resist convection, which is how heat moves through walls and ceilings, keeping them warm in the winter and cool in the summer.

This type of insulation is typically installed in new-construction homes and commercial buildings, and in existing homes and pole barns that haven’t been insulated before. It can be applied to attics, crawl spaces, basements, and rim joists. It’s also often used in foundations and walls of new construction homes, overhangs and knee walls, and concrete block walls in pole barns.
