The insulation calculator uses the following formula:
Volume = Area × (Thickness / 1000) m³
Thermal Resistance (R-value) = (Thickness / 1000) / λ (m²·K/W)
U-value = 1 / R-value (W/m²·K)
Packages = ⌈Area / Package Coverage⌉
Thermal Conductivity (λ): Mineral wool = 0.037, EPS = 0.035, XPS = 0.030, PUR = 0.025, PIR = 0.023 W/m·K
R-value: Higher R-value means better insulation. Typical walls need R ≥ 3.0 m²·K/W.
