calculate_insulation_r
Calculate thermal resistance R-value from thickness and conductivity for insulation specification (RT2020/RE2020).
Instructions
Compute thermal resistance R = thickness/lambda. Use for insulation specification (RT2020/RE2020). Inputs: thickness m, conductivity λ W/m·K. Returns R-value m²·K/W. See list_bundles for related 'construction' calculators.
