Austin R-value (insulation)

R-value quantifies the thermal resistance i.e. the amount of heat transfer retarded by a material. It is measured as a ratio of difference in temperature across the insulator and the heat transferred per unit area per unit time. Heat transfer around a house takes place in four ways – conduction, ...
