Durabarrier™

Durabarrier™ is a rigid sheathing, air barrier for all types of residential and commercial timber framed or steel framed buildings. Durabarrier™ resists high winds by equalising air pressure within the cavity to external conditions.

Durabarrier™ can be chosen as either a 4.5mm or 6mm-thick fibre cement sheet, sealed on the face and edges and specially manufactured for use as a rigid sheathing. 

Features & Benefits

What’s good about Durabarrier™ rigid sheathing:

  • Correct installation will ensure resistance to moisture damage and rot
  • Suitable for up to the Extra High Wind Zone or up to 2.5kpa (ULS) for specific design
  • Face-sealed to rapidly displace moisture
  • Provides short term weather tightness
  • Temporarily secures buildings ahead of cladding
  • BRANZ appraised (no 721, 2019) and tested against Table 23, NZBC Acceptable Solution E2/AS1
  • Both 4.5mm and 6mm sheets can be used for bracing
  • Durabarrier™ 6mm can be used in both our 30min and 60min FRR systems
