Majvest roll.


The sturdy and rainproof membrane Majvest provides for permanently windtight facades on the outside. SIGA-Majvest is highly tearproof and flexible, so it is easy and safe to lay. The material is diffusion-open and permanently protects the wall construction from condensation build-up.  With a width of 3 m and the practical cutting and bonding aid SIGA-Majvest can be applied very efficiently.
