WebR-Value is a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value the better the thermal performance of the insulation. The table below shows what levels of insulation are cost-effective for different climates and locations in the home. WebStudies conducted by the Department of Energy show that fiberglass insulation in an attic rated at R-19 performed at R-9 when temperatures outside dropped to -8°F due to convective currents within the insulation. Meanwhile, the R-values for Structural Insulated Panels INCREASE. ACME Panel SIPs are even greener.
