Majvest 200 is a mechanically-fastened, 3-ply membrane designed for above-grade moisture control and air barrier applications. 

Its protective polypropylene fleece layers stand up to the toughest jobsite conditions. A highly vapor-permeable, polymeric inner layer does the heavy multi-tasking: resisting harsh wind-driven rain and snow, while still protecting the wall beneath from condensation build-up.
Features
  • Tear-proof, flexible, 3-layer material resists damage during construction 
  • Printed cutting, laying, and taping guides reduce installation time 
  • Fabric-like material is quiet and wind-resistant
