Siga Majrex 200 1.5 x 50m

For even more security in wall/roof structures on the room side of thermal insulation, this vapour control layer with Hygrobrid technology helps especially in cases of problematical building physics. The Saga Majrex Vapour Control Layers (VCL) Membrane is a plastic layer that restricts the movement of warm, moist air from inside a property into the frame of the building. VCLs prevent excess moisture content from entering a wall's cavity, behind the insulation, eliminating moisture content.
