Enhanced Thermal Resistance

ZIP System® R-Sheathing Insulates and Protects.

The all-in-one ZIP System® R Sheathing panel provides a new approach to sealing and insulating the building envelope. One panel combines thermal, air and moisture resistance, while providing the excellent strength and durability you trust ZIP System® products to provide. This innovative new insulated system delivers installation convenience and exceptional, long-term performance, making it easier to meet the increasingly strict energy demands from codes and green building programs.

R Sheath
1 Continuous Foam Insulation Provides Higher R-value

System is designed to help meet new energy codes by increasing thermal performance while eliminating thermal bridging.

2 Engineered Wood Provides Structure and Durability

Engineered wood outer layer provides a nail surface for exterior cladding, trim and accessories.

3 Built-In Water Resistive Barrier Eliminates Housewrap and Felt

Specifically designed with optimal permeance levels to allow panels to breathe and dry out. In addition, it eliminates costly rework and provides instant rough dry-in with a 180 day exposure guarantee.

4 Continuous Air Barrier Creates Greater Energy Efficiency

By decreasing unwanted air leakage into and out of a building, it helps protect the R-value of insulation, which can reduce heating and cooling costs.

5 ZIP System Tape Permanently Seals All Panel Seams

Acrylic formulation provided superior adhesion and has been rigorously tested for long-lasting performance.
