Is your siding’s water-resistive barrier doing its job?

Feb 16, 2017

No matter how expertly your home’s siding is installed, there’s always a chance it might leak. To prevent damage to your home, you need a wall sheathing known as a water-resistive barrier (WRB), that provides a plane for draining off any water that seeps past the siding. Tyvek, for example, is a common WRB.

You also need an air barrier, which prevents that prevents the flow of air to boost energy efficiency. Air leaks can occur at seams and edges, and basement rim joist areas, to name a few.

James Hardie, the leader in fiber cement siding, developed HardieWrap®, a weather barrier that functions as both a water resistive barrier and an air barrier. This protective layer prevents air leakage while letting vapor escape and keeping water away from your home’s interior surface.

Climate has a significant impact on the effectiveness of the WRB and air barrier, so HardieWrap is engineered to accommodate those differences, indicated by HardieZone® regions. HZ5® is designed for the cold and wet climates that prevail in the northern states of the U.S. HZ10® is used in the hot and humid regions located in the southern states.

"The lap siding on the front of our home was failing so we decided to replace it all with James Hardie fiber cement siding. We knew this would be a job that needed to be handled correctly. We were apprehensive about hiring someone to handle what we knew would be a huge undertaking and were very pleased with the way this company performed. We would definitely recommend them.”
