Spray foam insulation has become an increasingly popular choice for homeowners and builders in recent years due to its many advantages over traditional fiberglass batt or roll insulation. Here are some of the key benefits of using spray foam insulation in your home:
Superior Air Sealing – One of the biggest benefits of spray foam is that it seals all the nooks, crannies, gaps, and cracks that allow airflow in and out of your home. This improves energy efficiency, reduces pollen/dust, and creates a quieter indoor environment. Fiberglass insulation can leave gaps which compromise insulation performance.
Higher R-value – Spray foam has a high R-value (insulating value) of around R-6 per inch. This means it provides excellent thermal resistance and helps keep indoor temperatures comfortable. In comparison, fiberglass batts have an R-value of only R-3 per inch. The higher R-value of spray foam translates into better insulation with less thickness needed.
Moisture Resistance – Spray foam is highly resistant to moisture and condensation. It won’t sag from moisture like fiberglass can over time. The closed-cell structure of spray foam prevents moisture absorption. This helps prevent mold, mildew, and wood rot.
Air Sealant – In addition to insulating, spray foam functions as an air barrier. It seals the building envelope and minimizes air leakage. Stopping air leaks makes your HVAC system more efficient as it doesn’t have to work as hard.
Long Lasting – Spray foam insulation is durable and long-lasting if installed correctly. It won’t settle or deteriorate over time like other insulation solutions. It’ll provide reliable thermal performance for the life of your home.
Improved Comfort – The combination of insulation, air sealing, and moisture resistance provides improved indoor comfort. Homes insulated with spray foam maintain more consistent temperatures and have fewer drafts or cold spots.
While spray foam insulation costs more upfront than fiberglass, it offers superior insulation performance and air sealing that can pay off over time in energy savings. If properly installed, it’s a smart investment that provides comfort and efficiency for the life of your home.
