Product Specifications



Reinforced paper-based smart vapor retarder and air sealing membrane. Ideal environmentally friendly air barrier option for the environmentally conscious contractor.


1.35 m x 50 m (53" x 164')
Roll Area: 67.5 m2 (724 sf)


  • Made from recycled paper (50% of weight is recycled)
  • Provides excellent protection as smart vapour retarder for cellulose, mineral wool, fiberglass, wood fiber, sheep wool, and straw bale insulation
  • Reinforced layer allows it to be used as blow-in mesh (use counter battens to support DB+)


  • DB + is recycled paper which is strengthened with a bi-directional reinforcement layer
  • Use with either, batts, boards and as mesh for blown-in insulation
  • Vapour variable profile protects the interior of the building envelope in most climatic conditions, making it the most sustainable protection/airtight membrane for the thermal insulation
  • Vapour retarding in winter - 0.8 Perm (sd value 4 m) - protection against condensation
  • Vapour open in summer – 8.0 Perm (sd value 0.4m) - facilitates drying to the interior
  • Lightweight and easy to install, especially compared to OSB/Plywood
  • Fully recyclable
