Metal Building Insulation Benefits, Types, Cost & Tips
WebR-value figure is usualy provided by the manufacturer of a particular insulation product and is shown in the product description. R-value figure can be calculated from the equation: R value = thickness (m)/Thermal Conductivity (W/mK) Unlike thermal conductivity, thermal resistance (R-values) solely depend on the material’s thickness.
