Kingspan Vapor Barrier SAR

Air & Vapor Barrier

The Kingspan Vapor Barrier SAR membrane is a self-adhered vapor and air control layer comprised of an SBS asphalt and rubber blended formulation and a factory-laminated tri-layered woven sheet. It’s intended to be used as a vapor retarder in Kingspan Roofing Systems.


Product Highlights

  • Manufactured in the U.S.A. with globally sourced materials.

  • Vapor & Air Control Layer: very low vapor and air permeability; approved as a vapor retarder in Kingspan Roofing Systems.

  • Approved for application to a variety of substrates including plywood, gypsum or concrete board, concrete, asphalt, or metal.

  • Self-Sealing and Self-Adhering Technology expedites installation.

  • Safe, Nonslip, and UV-protected surface provides traction as a walkable, temporary weather-protected surface against UV exposure and puncture damage for up to 90 days.

  • Can be installed on plywood, gypsum or concrete board, concrete, asphalt, or metal. Primer may be omitted when adhering directly to a steel deck in a mechanically attached system.  All other applications and substrates must be primed prior to installation. Please use the Kingspan LVOC Sprayable Bonding Adhesive to prime the substrate in these applications.
