SIGA Majrex 200 Vapour Control Membrane, 1.5 m x 50 m Roll
Majrex 200 is a SIGA vapour control layer that uses Hygrobrid technology. It goes on the warm side of the thermal insulation and forms an airtight layer that helps keep moisture from building up in the wall cavity.
The membrane is dimensionally stable, so it lays quickly without wrinkles, and it carries a printed cutting and laying aid. It has no integrated tape, so laps and edges are sealed with a separate SIGA tape such as Sicrall or Rissan.
