What is the “R” Value of the Warmup Insulation Boards?
Because the boards are designed to create a thermal break between your sub floor and your heated floor, the “R” value for the Warmup Insulation boards is only 1.08. The boards are not designed to hold the heat, but to reflect the heat upwards into the floor tile instead of allowing heat to warm up the concrete slab below.
The WIB boards will save you money by acting as a very efficient thermal barrier. Heats up times in our testing facility were cut down from 2.5 hrs. to just 25 minutes. With a 78% faster ramp up time, your system will save you 71% in electrical usage.
