Novia 509B Lining Paper is best suited for use as a high-performance lining layer in temporary protection, wall lining, and separation applications within construction projects. Its bitumen-based composition, sandwiched between two kraft paper layers, provides excellent moisture resistance and durability, making it ideal for use in floor, wall, or ceiling assemblies where basic vapour resistance or separation from other building materials is required. It is commonly used in timber frame construction as a cavity lining or for packaging and protection purposes on-site. Novia 509B is not intended as a primary vapour control layer but offers a reliable solution for low-demand barrier and protective lining needs.
