Applications

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

Advantages

• 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+)

Properties

• 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
