TremVap Air and Vapour Control Layer
RW145 is a self-adhesive bituminous membrane, which consists of a selfadhesive bituminous compound reinforced by a composite aluminium foil with integral glass-fibre mat.
Developed specifically for use as an air and vapour control layer or carrier membrane in Tremco warm roof systems. RW145 can be used on most common substrates such as concrete, plywood/OSB and metal decks as a air and vapour control layer, and TremTherm insulation boards as a carrier membrane.
