Spray foam insulation has various effects on a home after installation. It’s important to know these effects as a contractor, whether you’re using these benefits to market your services or teach clients more about your products during an appointment. Keep reading to learn three ways spray foam insulation impacts HVAC performance after the installation process.

Makes HVAC Systems More Efficient

A home will often lose air through cracks and gaps in the walls and insulation. When a home loses hot or cool air, the HVAC unit must work harder to heat or cool the space. Because spray foam insulation provides an air-tight seal, it reduces potential air and energy loss. This is one of the biggest benefits of spray foam for homeowners because it means their homes require smaller HVAC units that don’t consume as much power. Having a smaller unit or turning down the system’s settings also reduces energy costs, making a home more energy efficient.

Improves Air Quality

Old, uninsulated homes often have poor air quality due to an inefficient HVAC and air transfer process. The air that naturally enters a home isn’t filtered, so it can carry pollutants into the home. Spray foam prevents pollutants from entering through gaps, promoting cleaner indoor air. Additionally, certain types of spray foam insulation prevent air and moisture from entering a space. Closed-cell spray foam provides both moisture and air barriers, which prevent moist and warm air—two components of mold growth—from accumulating in the home. It keeps indoor air free of spores and pollutants.

Insulated Homes May Need Humidifiers

One thing to about know spray foam’s impact on a home is that it can limit ventilation. While spray foam insulation is extremely efficient and prevents air transfer, this means the home relies more on its HVAC system for ventilation. Make sure that your client’s home has plenty of air access points to keep fresh air coming in and out through controlled means.

You may also need to assess the humidity of certain parts of the home, especially in areas that don’t get much ventilation, such as the attic and basement. These areas may feel humid because moisture can’t escape through cracks and gaps. As a contractor, you can suggest homeowners buy a dehumidifier to keep their homes comfortable.
