Air Barrier & Water Resistive Membrane Blue Majvest® 200 1.5Mx50M 1/CS

SIGA Majvest® 200 is a diffusion-open, wind and rainproof facade membrane for permanent protection of the exterior wall and maintaining the functionality of the thermal insulation. This mechanically-fastened, 3-ply membrane designed for above-grade moisture control and air barrier applications. Its protective polypropylene fleece layers stand up to the toughest jobsite conditions. A highly vapour-permeable, polymeric inner layer does the heavy multi-tasking: resisting harsh wind-driven rain and snow, while still protecting the wall beneath from condensation build-up. Provides the perfect foundation for durable water-resistive and air-barrier assemblies.
