HARDIEWRAP WEATHER BARRIER
Just like siding, a better weather barrier starts with better material. HardieWrap weather barrier is a premium, non-woven water-resistive barrier. It contains a unique MicroTech coating that provides a better balance of water resistance and water vapor permeability, reducing water intrusion while releasing moisture vapor from inside to dry out the wall cavity. HardieWrap weather barrier also delivers superior air resistance to reduce energy loss. An 11 mil thick sheet provides better strength than other products.
As with all of our exterior products, HardieWrap weather barrier is engineered for climate. In reviewing the climatic factors that affect weather barrier performance, we determined the predominant factors that affect weather barrier performance are temperature and humidity. The temperature and humidity differences align with the two HardieZone regions. So we created two weather barriers: one engineered for cold/wet climates and the other engineered for hot/humid climates. HardieWrap weather barrier is offered in two high performing products to meet the needs of HZ5 and HZ10 regions.
