Moldblock Technology

HardieBacker™ Cement Board with Moldblock™ Technology delivers superior protection against mold.
HardieWrap™ weather barrier is an innovative, higher performing weather barrier made by James Hardie, maker of America's #1 brand of siding. HardieWrap weather barrier provides a balance of water resistance and water vapor permeability, reducing water intrusion from the outside while releasing water vapor from inside the home to dry out the wall cavity.

The Science Behind the Siding™

HardieWrap weather barrier is a premium, non-woven water-resistive barrier. It contains a unique MicroTech™ Coating that enables higher performance:
  • Coating provides a balance of water holdout and breathability
  • Superior air resistance to reduce energy loss in the home
  • Thicker 11 mil sheet for exceptional tear resistance
Together, HardieWrap™ weather barrier, HardieWrap™ Flashing, HardieWrap™ Flex Flashing and HardieWrap™ Seam Tape work with the cladding to form an important part of a home's weather protection envelope to prevent water damage, mildew and energy loss.1
