ROOFMATE RL-X
ROOFMATE™ RL-X is the STYROFOAM™ solution for insulating single-ply roof decks. ROOFMATE RL-X boards provide a lightweight, rigid substrate beneath light-coloured single-ply polymeric membranes on flat or low slope metal decked roofs. The large area and high dimensional stability of ROOFMATE RL-X boards minimises the installation time as well as the number of fixings required.
ROOFMATE RL-X can also be used to insulate warm pitched roofs at rafter line. ROOFMATE RL-X boards are for installation above the rafters with ROOFMATE RL cut to size to fit between the rafters. The insulation is supplied in large boards for rapid coverage.
