Case Studies

Kaikoura Island Prefabricated Lodge

The collaboration between Architecture+Women-NZ and Strachan Group Architects (SGA) has been a successful partnership between timber products and great prefabricated design.

The Architect, The Builder and The Homeowner - Ecoply Barrier

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.

Vital Support Where It Counts

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.

Wrapped Up For Winter

Ecoply Barrier was used as protection against the elements down south.

Deep South Higher Education

A generous outdoor plaza is at the heart of a significant addition to the Otago University campus.

Braced for the Elements

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.

Braced For All Levels

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.

Brace for the Future

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.
