What is R-value?

Insulation is rated in terms of its thermal resistance, which indicates its resistance to heat flow. The higher the “R-value”, the more effective the insulation. R-values of thermal insulation vary depending on the type of material, its thickness and its density. For multi-layered installation, the R-values of the different layers are simply added up. In short, installing more insulation on your building increases the R-value and the resistance to heat flow.
