Shield Your Shed from the Elements
PREVENT UNWANTED GAPS
Unlike plywood and house wrap, with Zip System® sheathing panels, the defensive barrier is built-in to prevent any unwanted gaps from forming. Panels are sealed together with Zip System® joint sealant products to armor every inch of your shed with extra coverage.
BREATHABLE WATER-RESISTANCE
Integrated Zip System® sheathing keeps water out but allows vapor to pass through. As a water-resistive barrier, it protects against weather damage while providing unrivaled drying potential.
SHIELDS AGAINST DRAFTS
This tight barrier forms a continuous defense against air leakage and drafts for a more comfortable interior space. If you plan on adding air conditioning or heat to your shed, we recommend Zip System® sheathing for increased energy-efficiency.
RATED FOR DURABILITY
Available with a Structural I Rating, Zip System® sheathing panels meet seismic and high wind zone condition requirements. Their 30-year limited warranty ensures your shed remains ready to withstand the harsh New England elements for decades.
