For HVAC spray foam insulation applications, 2 LB closed cell spray foam is an ideal choice.
2 LB closed cell spray foam has a high R-value (typically around R-6 to R-7 per inch of thickness), which means it provides excellent thermal insulation. It effectively reduces heat transfer, helping to keep buildings warmer in the winter and cooler in the summer. This helps to make it ideal in HVAC applications.
Besides reducing heat transfer from the duct work to the surrounding areas housing the ductwork, HVAC spray foam insulation applications dampen noise and vibrations that tend to occur, especially when using rigid duct work. The result is a quieter living or working area that uses less energy annually for heating and cooling.
2 LB Closed Cell Spray Foam Key Features:
- Density: The “2 lb” in the name refers to the density of the foam—2 pounds per cubic foot (lb/ft³). This density indicates a higher concentration of material in the foam, making it denser and more rigid compared to lower-density foam types (e.g., 1/2 lb or 1 lb spray foam).
- Closed-Cell Structure: The foam contains millions of tiny, closed-off cells. This structure makes it more resistant to moisture absorption compared to open-cell foam, providing a strong vapor barrier and helping to prevent water damage and mold growth. It is ideal for areas where moisture is a concern, such as basements, crawl spaces, exterior walls and is ideal for HVAC spray foam insulation applications.
