Majvest® 200 Air Barrier & Water Resistive Membrane | Blue | 1.5 m x 50 m

Description

SIGA Majvest® 200 is a high-performance, diffusion-open facade membrane designed to deliver reliable wind and rain protection for exterior wall systems. Engineered for above-grade applications, it helps preserve the effectiveness of thermal insulation while supporting efficient moisture management. This mechanically fastened, 3-layer membrane acts as both an air barrier and a protective shield against external elements, ensuring long-term durability of building envelopes.

Constructed with robust polypropylene fleece layers, it withstands demanding jobsite conditions with ease. Its advanced vapor-permeable inner layer allows moisture to escape from within the wall structure while preventing the penetration of wind-driven rain and snow. This balance helps reduce condensation risks and enhances the overall performance of wall assemblies, making it an ideal base for long-lasting water-resistive and air-barrier systems.
