ZIP System® R-12 Insulated Sheathing (4' x 8' x 2.5")

The All-In-One Structural & Thermal Barrier

Streamline your build with the ZIP System® R-12 R-Sheathing. This high-performance panel combines structural OSB, a built-in water-resistive barrier, and R-12 polyisocyanurate foam insulation into a single, easy-to-install sheet. Eliminate the need for separate house wrap and rigid foam applications while drastically improving the energy efficiency of your structure.

Why Choose ZIP System® R-Sheathing?

Superior Thermal Performance: The integrated R-12 foam core provides a continuous insulation layer, significantly reducing thermal bridging and lowering heating/cooling costs.

Integrated Weather Barrier: The built-in water-resistive barrier eliminates the need for house wrap. Just install the panels and tape the seams with ZIP System™ tape for a permanent, airtight seal.

Enhanced Productivity: Save hours on the job site by installing your structural sheathing, vapor barrier, and insulation in one pass.

Structural Integrity: Meets building code requirements for structural racking strength while providing a flat, nail-base surface for siding attachment.
