The All-In-One Structural & Protective Barrier

Streamline your build with the industry-leading ZIP System®. This high-performance structural panel eliminates the need for traditional house wrap or felt, combining a structural OSB layer with a built-in, water-resistive vapor permeable barrier.

Why Builders Choose ZIP System:

Two-In-One Protection: Provides a structural shear wall and a weather-resistive barrier (WRB) in a single installation.

Superior Moisture Management: The integrated overlay keeps water out while allowing the panel to "breathe," preventing trapped moisture and rot.

Air-Tight Seal: When used with ZIP System™ tape, these panels create an airtight building envelope, significantly increasing energy efficiency and reducing HVAC loads.

Fast Installation: Skip the house wrap. Simply hang the panels and tape the seams to achieve a rough-in dry-in in record time.

Tongue & Groove Edge: The precision-engineered T&G profile ensures a flat, stable surface and easy alignment during roof or wall applications.
