Utilizing SIGA's new Hygrobrid technology, Majrex is the vapor control layer that allows moisture travel in only one direction. This protects the interior of the wall assembly from damaging moisture penetration and allows the cavity to release moisture into the interior of the space (as well as to the exterior if one is using a vapor-open exterior membrane, such as SIGA Majvest), while preventing moisture intake from the inside.
Sturdy, flexible, and dimensionally stable
Can be laid quickly, easily, and without wrinkles
Uni-directional moisture transport - moisture travels from the wall cavity, ensuring dryness in the wall cavity
