Spray Foam is an excellent way to insulate your home. The substance is a liquid that expands as it is applied, allowing it to fit into complex structures and hard-to-reach places. The foam’s R value indicates its resistance to heat flow. The higher the R value, the better. It can be applied to the entire house or just to a specific area. You can even apply it to your crawlspace, basement, or wall if you want.

One of the biggest differences between fiberglass and Spray Foam is that fiberglass insulation requires almost no training. This type of insulation requires no drying or curing time, so it is a good choice for projects where other trades must continue working. However, spray foam is a more technical material that requires precise application. To become an expert in applying it, you must undergo a rigorous training program. The most important safety measures include chemical protective clothing and full-face supplied air respirators.

The Spray Foam Coalition is a nonprofit organization that advocates for the use of spray polyurethane foam (SPF). It supports the energy-efficient use of SPF, promotes scientific research, and advances technical knowledge and safety. Its mission is to help the industry become a more valuable resource. The Coalition is the voice of the spray foam industry and will continue to advocate for better public policies and environmental protection. So, how do you get the most from your investment?

Open cell polyurethane foam (SPF), also known as 1/2-pound, weighs between 0.4 and 0.6 pounds per cubic foot and is applied to a substrate with a spray gun. Once cured, this foam expands by 150 percent of its original volume and forms a semi-rigid plastic insulation. Its blowing agent is water. As a result, SPF is easy to trim and cut.

There are two types of Spray Foam: open cell and closed cell. The open cell variety is less dense than half-pound foam and is cheaper to buy. It is best for most commercial projects. The R-value of the spray foam depends on the material used. It should be higher than the R-value of the previous insulation in the same area. The lower R-value of the spray foam will give you more insulation.

Open-cell spray foam effectively blocks the movement of both air and moisture. Moisture is vapor, which creates humidity. It is the main cause of heat and cold. The closed-cell kind is nearly vapor-impermeable. It blocks bulk moisture and water vapor. It is also a great choice for sealing cracks and holes in walls. The versatile product can be used in many different applications.
