Barrier class "PREMIUM"
Roll Waterproofing Self-Adhesive Bitumen-Polymeric Material
OS GCH Barrier
Material Description:
OS GCH Barrier has a rot-resistance base (polyester, glass fabric) coated with bitumen-polymeric astringent material on both sides. The lower surface of Barrier is covered with self-adhesive layer. Coarse grit is used as the upper protective layer and anti-adhesion film as the lower one. The material has a lengthwise strip protected with anti-adhesive film for arrangement of jointing.
Material adhesive features are determined by utilization of special types of polymers, which allows its usage on all types of combustible bases.

Application:
OS GCH Barrier is used as the backing material for flexible tiles and vapor sealing in various structures.
