SOPREMA SOPRAVAP'R is a self-adhered vapour barrier membrane composed of SBS modified bitumen with a tri-laminated woven polyethylene facer, designed specifically for insulated roof systems.

The membrane can be installed over common roofing substrates including steel, concrete, plywood, gypsum, cement boards and asphaltic panels. Its self-adhered underface allows for efficient installation by removing the silicone release film and bonding the membrane directly to the prepared substrate.

SOPRAVAP'R provides very low vapour permeance and excellent airtightness, helping control air and moisture movement through the roof assembly. It also offers strong puncture and tear resistance for durability during installation.

Designed for cold-weather installation, SOPRAVAP'R has a minimum application temperature of -10°C (14°F) and low-temperature flexibility below -30°C (-22°F).

The 45" × 134' roll provides 500 sq. ft. gross coverage and approximately 468 sq. ft. net coverage after required overlaps.
