What does R Value mean ?


Warmup Insulation Boards

The R value is a measure of thermal resistance used in the construction industry.

The higher the R value the better an insulator (e.g. 10mm Warmup® Insulation Boards have an R value of 0.28 m²K/W and the 20mm Warmup® Insulation Boards have an R value of 0.58 m²K/W). All buildings should strive for the highest possible R values to reduce the amount of energy used.
