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 secondary 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. brick layers etc

Product Technical Statement
The collaboration between Architecture+Women-NZ and Strachan Group Architects (SGA) has been a successful partnership between timber products and great prefabricated design.
Zane Raphael of Smith & Sons, renovation and extension specialists, moved his family into a 1960s Auckland home with plans to renovate and create a safe, healthy, dream home for his family.
Vision West Community Housing provides short term and long term supported rental housing in West Auckland. Their aim is to provide safe, healthy, affordable, quality rental housing for low-income families. Ecoply Barrier was the obvious solution for this project as it could benefit the complete build with its bracing properties, speed of installation and weather-tightness.
A generous outdoor plaza is at the heart of a significant addition to the Otago University campus.
A new family home, situated by the ocean, in the extra high wind zone of the Taranaki region required an upgrade from a standard rigid air barrier board to Ecoply Barrier.
A three-storey home situated on the slopes of Titirangi's Wood Bay utilised the benefits of Ecoply Barrier for quick enclosure along with the added bracing of a rigid air barrier system.
Ecoply Barrier was used in place of building wrap to create a fully drained and vented rigid air barrier. With the growing awareness around leaky building a requirement for the Kaplan International College new residence bulding in Christchurch was to provide not only a building which was cost effective but one which had increased protection against leaks into the building envelope, especially given the building is located in a high wind zone area.
