spray foam insulation offers a powerful seal around the building envelope, which means it doesn’t let air leak into the home or out of it. This prevents hot North Carolina summers and cold winters from overworking the furnace and air conditioner, reducing energy bills. In fact, with the power of an air barrier and a good insulation layer, you may have days when your HVAC system doesn’t run at all, which will save you money on electricity expenses and also reduce the need for space heaters, box fans, and ceiling fans.
Different Types of Spray Foam Insulation Explained
Unlike fiberglass or blown cellulose, spray foam won’t compress and lose its R-value over time, which allows it to achieve an R-value of 3.5 per inch. Its long lifespan and durable nature makes it an excellent choice for new construction projects, attics, crawl spaces, and rim joists in existing homes, as well as pole barns and commercial buildings.
While spray foam is very effective, it does require specialized equipment to install correctly. This is why many homeowners choose to hire professional contractors for installation. This is important for consistency, safety, and getting the best results possible. Spray techs have the experience and training to know how to properly use and maintain their rigs, so you can count on quality workmanship and a long-lasting product.
When choosing spray foam, opt for a green option that uses low GWP blowing agents like HFOs. Closed-cell polyurethane spray insulation products such as Solstice FR and HandiFoam High Density feature this type of insulation, which reduces environmental impact by up to 99.9 percent over spray foam alternatives that continue to use HFCs as blowing agents.
