SIGA Majrex 200 - a vapor control layer for safe, airtight building envelopes

SIGA Majrex 200 is a fiber-reinforced, modified PE/PP sheet membrane designed as an interior air-barrier and vapor control layer. With Hygrobrid® technology, the permeance of Majrex 200 varies depending on the direction of vapor flow, making it currently the only directional smart vapor control membrane on the market. When used with compatible SIGA system products, SIGA Majrex 200  forms an effective air barrier to avoid building damage, drafts and heat loss.
