HardieWrap™ Weather Barrier Solution

Over 4 million homes in North America are protected by James Hardie® siding products. That's a testament to the confidence builders and homeowners have in our building materials.

James Hardie's mission is to innovate A Better Way to Build™. We pioneered a superior siding — the first layer of defense against the weather elements. Now, HardieWrap™ weather barrier gives you a second layer of defense. Together, the siding and HardieWrap weather barrier work to form a major part of your home's weather protection envelope.

HardieWrap weather barrier is a higher performance, water-resistive barrier designed to provide better protection for your home. When properly installed under James Hardie® fiber-cement siding, it gives your home an unmatched double line of defense against water damage, mildew and energy loss.

HardieWrap weather barrier offers you more — and it's backed by James Hardie, a name you can trust.
