š How We Calculate
The insulation calculator uses the following formula:
Volume = Area Ć (Thickness / 1000) mĀ³
Thermal Resistance (R-value) = (Thickness / 1000) / Ī» (mĀ²Ā·K/W)
U-value = 1 / R-value (W/mĀ²Ā·K)
Packages = āArea / Package Coverageā
Thermal Conductivity (Ī»): Mineral wool = 0.037, EPS = 0.035, XPS = 0.030, PUR = 0.025, PIR = 0.023 W/mĀ·K
R-value: Higher R-value means better insulation. Typical walls need R ā„ 3.0 mĀ²Ā·K/W.
