Barrier Ply

Plywood City are proud agents for Ecoply® Barrier and have this product as a stock item.

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.

The Ecoply Barrier System meets the NZ Building Code requirements for rigid underlays.

Barrier ply can be exposed for a maximum of 180 days during the construction cycle, meaning a fast close-in which allows for earlier interior finishing on a site.


Plywood City also stock the Ecoply Barrier – Sill Tape, Frame Sealing Tape and Sealing Tape transform our sheathing plywood panels into a seamless protective barrier for your construction project.

All tapes are proven to deliver an airtight and watertight seal. The Ecoply Barrier ‘rigid air barrier system’ tapes save you time and money on the job; and you can leave the site with confidence it will perform.
