New Zealand houses are typically draughty, badly ventilated and under-insulated, making them difficult and expensive to heat. Fortunately, the Ecoply Barrier System by Carter Holt Harvey Woodproducts is a solution to protect and make homes warmer and more comfortable.
The Ecoply Barrier System is engineered to provide a continuous enclosure around the building envelope, and also to be impermeable to airflow and resistant to the vacuum of air pressure differentials.
BRANZ-appraised, the Ecoply Barrier System is a weather tight rigid air barrier used for drained and vented cavity systems outside the building frame, effectively replacing traditional building wrap. This system can provide structural bracing and forms a strong secondary line of defense against moisture penetration into the building envelope.
Airtight buildings are becoming more common due to the many benefits of energy efficiency and air-flow control achieved within the home. The Ecoply Barrier System forms a tight seal to minimize air leakage, preventing unwanted air movement into and out of the house through the wall cavity, thereby keeping homes drier and safer.
Moisture control is critical in buildings, because wherever air moves water vapour can follow. Ecoply Barrier plywood is a smart vapour retarder and is engineered for optimal breathability for fast vapour movement and drying of the wall, reducing condensation build-up in the wall cavity.
