SIGA Majvest® 200

Majvest 200 membrane provides the perfect foundation for durable water-resistive and air-barrier assemblies. Majvest 200 is a 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 vapor-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.
