Roll Radiant is an exciting new all in one acoustic, thermal and moisture barrier mat designed for use with underfloor heating systems. Based on the original Roll impact sound insulation mat – Roll Radiant has a thermal reflective backing which also acts as a moisture barrier. This reflecting layer ensures that heat from the undefloor heating pipes radiate back into the room instead of being lost in the substructure beneath.
Roll Radiant can be used with both anhydrite and cement based screeds at thicknesses as low as 50mm. upwards.
Roll is available in 5mm, 7mm and 10mm versions.
