CHH® Ply | Ecoply® Barrier Structural Plywood

By Carter Holt Harvey
Website

The Ecoply® Barrier System provides a weather tight and rigid air barrier for drained and vented cavity systems outside the building frame. This effectively replaces traditional building wrap in the cavity, while providing structural bracing and forming a strong second line of defence against moisture penetration into the building envelope.

Features & Benefits

  • Temporary weather protection to the building envelope prior to cladding installation
  • Fast close-in allows for earlier interior finishing
  • Provides structural bracing when installed as per bracing specifications
  • The panels can be exposed for a maximum of 180 days during the construction cycle. The sealing tapes can be exposed for a maximum of 180 days during the construction cycle. This means there are no hold-ups while the cladding has to be installed, e.g. bricklayers etc
  • Manufactured from sustainably-grown NZ plantation pine
  • Sheet dimensions: 2440/2745 × 1200 mm
  • H3.2 CCA treated
  • Low formaldehyde emission (E0)
  • Low volatile organic compound (VOC's) surface coating
  • FSC® certified (FSC-C012019) upon request

Powder Coating Technology

The technologically advanced film coating on Ecoply® Barrier structural plywood panels is specifically formulated to resist the effects of weathering, including sun and moisture, both during construction and for the life of the completed building.

Coating benefits:

  • The continuous film formed by the powder coating process repels water and reduces absorption rates compared to uncoated wood-based materials.
  • The edges of Ecoply Barrier sheets are coated and sealed.
  • High film build (60-80 microns) delivers a smoother and more durable sheet surface for better moisture drainage in cavity construction applications.
  • Sealer coating contains low Volatile Organic Compounds (VOC).
  • Beige coloured sealer coating can be exposed to the weather up to 180 days prior to installation of the exterior cladding.

Compliance:

  • The Ecoply Barrier System meets the NZ Building Code requirements for rigid underlays as outlined in Section 9.1.4; the performance requirements of Table 23 of E2/AS1; and has been tested for wind speed exceeding Extra High wind zone as defined in NZS 3604. Testing has been completed to provide solutions for buildings outside the scope of NZS 3604.
  • BRANZ appraised for use as a rigid sheathing and temporary weather-protecting sheathing on timber-framed buildings
  • Independently certified as compliant with AS/NZS 2269 - Plywood Structural
  • H3.2 CCA treated in accordance with AS/NZS 1604.3
