Delving Into the R-Value of Spray Foam Insulation

Understanding R-Value and Its Importance

R-value is the industry standard for measuring insulation’s resistance to heat flow: the higher the R-value, the more effective the barrier. In both commercial and residential applications, achieving the right R-value is critical for maintaining year-round comfort and minimizing energy expenditures. As energy costs rise and building codes tighten, property managers are turning to high-performance solutions like spray foam insulation to meet or exceed required R-values.

Spray Foam Insulation: Closed-Cell vs. Open-Cell

Spray polyurethane foam (SPF) stands out among insulation materials for its superior R-value per inch:

  • Closed-Cell SPF delivers R-values between approximately R-6.0 and R-7.0 per inch. Its dense, rigid structure both insulates and acts as an air and moisture barrier.
