140mm Kingspan Thermaroof TR24 - (pack of 3)

140mm Kingspan Thermaroof TR24 is a rigid insulation board used for flat roof insulation, consisting of a rigid thermoset insulation core, covered with a glass tissue coated with bitumen. Its upper surface is finished with a thermo fusible polypropylene fleece, while the lower surface is covered with mineralized glass tissue. When the product is installed, the flat roof fall should be steep enough and smooth to avoid rainwater pools. It is especially designed to work with most fully bonded torch applied multi-layer bituminous waterproofing. It is applicable in both new build and refurbishment projects, though it should be installed over a vapor control layer (unless used jointly with sealed metal deck) in new build projects while existing bituminous waterproofing membrane can be used as a vapor control layer, if not, this layer should also be added in refurbishment projects.
