Benefits of Spray Foam Insulation

Due to its total coverage and the tight seal it creates, spray foam insulation is ideal for small gaps, crevices and cracks in your home’s envelope, and around piping and ductwork.

Commonly made of polyurethane, it’s applied in liquid form and dries quickly, expanding into a thick foam. Spray foam insulation can help:

  • Maximize efficiency: With properly installed spray foam insulation, your San Antonio home could benefit from lower energy costs.
  • Increase comfort: By keeping cool air inside during summer and warm air inside during winter, this insulation can help make your home more comfortable year-round.
  • Reduce noise: Spray foam insulation can be a noise barrier for unwanted outdoor and between-level/wall indoor sounds.
  • Improve performance: With your home’s heating and cooling systems having to work less, you can expect to get a better, longer-lasting performance out of them.
  • Eliminate mold growth: Spray foam insulation is a great defense against air and moisture infiltration, which could help mitigate mold and mildew growth.

Spray foam insulation outperforms traditional batt or blown-in insulation thanks to its ability to form an airtight, water-resistant seal by expanding and filling cracks and crevices in hard-to-reach places.

What’s the R-Value of Spray Foam Insulation?

R-value describes how much insulating power a material has. The higher the R-value, the more heat that material can resist. Therefore, materials with higher R-values will be better insulators.

According to the Department of Energy, closed-cell foam has an insulation R-value of about R-6.2 per inch of thickness. Open-cell foam, which isn’t as dense, has an R-value of approximately R-3.7 per inch of thickness.

Closed-cell spray foam has a significantly higher thermal resistance factor than fiberglass or cellulose insulation for a tighter building envelope, enhanced comfort and decreased heating and cooling costs.
