What is R Value?

R-value is a measurement that rates how resistant a product is to heat flow, measuring the ability of heat to transfer from one side of an object to another. 

Our calculator helps you measure what r value for exterior walls  you may be looking for, as well as for different applications. i.e. ceiling insulation R value, R value for walls and more.
