Majvest® 200 Air Barrier & Water Resistive Membrane | Blue | 3 m x 50 m | 1/Case

Description

SIGA Majvest® 200 is a premium, diffusion-open facade membrane designed to deliver dependable wind and rain protection for exterior wall assemblies. It helps safeguard building structures while preserving the efficiency of thermal insulation by allowing moisture vapor to escape. Ideal for above-grade applications, this mechanically fastened, multi-layer membrane functions as both an air barrier and a water-resistive layer, supporting long-term building performance.

Built with durable polypropylene fleece outer layers, it is engineered to withstand harsh construction site conditions. Its advanced vapor-permeable inner core prevents the penetration of wind-driven rain and snow while allowing internal moisture to dissipate, reducing the risk of condensation within the wall system. This makes it an excellent choice for creating strong, long-lasting air barrier and weather-resistant assemblies.

Key Features:

• Diffusion-Open Technology: Enables moisture vapor to escape while blocking external elements
• Wind & Rain Defense: Protects walls from severe weather exposure
• Multi-Layer Construction: Durable 3-ply design for enhanced strength and reliability
