Thermal Resistance – (“R” Rating)
The “R” Rating is a measure of thermal resistance. In the instance of flooring, it is the measure of the floor system’s ability to resist temperature load from one side of the panel and/or underlay, to the other.
This information is of benefit when assessing the performance if in-floor heating systems. The measure is commonly required when evaluating a building’s all round energy efficiency.
The “R” Ratings for Quick-Step with both Standard Combi-Lay and Quiet Step Combi-Lay Underlays are:
Quick Step 8mm on Premium Combi-Lay R = 0.12
Quick Step 8mm on Quiet Step Combi-Lay R = 0.135
