Vapor barrier

TECHNOELAST VB 500 SELF

Flexible reinforced SBS-modified bitumen membrane TECHNOELAST VB 500 SELF is used as a high-performance vapor barrier in roof waterproofing systems.
Self-adhesive bottom surface and high tensile strength ensure the ability of the material to withstand the weight of the person standing between the corrugations of the profiled metal deck without breaking or stretching.
The material is produced on a base of a glass net carrier coated with SBS-modified self-adhesive bitumen binder.

The membrane is protected on the bottom side with an easily removable siliconized film, while the top surface is covered with aluminium foil.
