52.5mm Unilin Safe-R SR/TB-MF is a composite insulated panel of 40mm Phenolic core with a composite foil facing bonded to a 12.5mm tapered edge plasterboard for internal applications, mechanically fixed. Unilin Safe-R SR/TB-MF is designed to provide high levels of thermal insulation and dry lining in one operation for masonry walls. Unilin Safe-R SR/TB-MF incorporates an integral vapour control layer, which helps to reduce the risk of condensation. It can be used as a composite plasterboard for internal walls, sloped roofs and ceilings.
