The Trojan Cork Underlay - 2MM allows transmission of heat, so that you can reach the top efficiency of your flooring heating system. It is recommended that the heat transmission resistance of flooring and underlay must not exceed a value of RB=0.15m2K/W, this means that the thinner the engineered or laminate floor the better the transfer of heat. This underlay has a 18db sound reduction and covers an area of 10m².
