WARNING: AVOID BREATHING SILICA DUST
James Hardie
®
products contain respirable crystalline silica, which is known to the State of California to cause cancer
and is considered by IARC and NIOSH to be a cause of cancer from some occupational sources. Breathing excessive
amounts of respirable silica dust can also cause a disabling and potentially fatal lung disease called silicosis, and
has been linked with other diseases. Some studies suggest smoking may increase these risks. During installation or
handling: (1) work in outdoor areas with ample ventilation; (2) use fiber cement shears for cutting or, where not feasible,
use a HardieBlade
®
saw blade and dust-reducing circular saw attached to a HEPA vacuum; (3) warn others in the
immediate area; (4) wear a properly-fitted, NIOSH-approved dust mask or respirator (e.g. N-95) in accordance
with applicable government regulations and manufacturer instructions to further limit respirable silica exposures.
During clean-up, use HEPA vacuums or wet cleanup methods-never dry sweep. For further information, refer to our
installation instructions and Material Safety Data Sheet available at www.jameshardie.com or by calling 1-800-9HARDIE
(1-800-942-7343). FAILURE TO ADHERE TO OUR WARNINGS, MSDS, AND INSTALLATION INSTRUCTIONS MAY LEAD
TO SERIOUS PERSONAL INJURY OR DEATH. SD050905

HardieZone
®
– Engineered for Climate
®
James Hardie, the undisputed leader in fiber cement has always made the world’s most resilient siding, and now we have
made it even better. For the first time, siding has been engineered for climate. So you get the right board for the right climate.
We call it the HardieZone
®
System.
We took the 8 climatic variables – that affect long term performance of the exterior into account and by combining them
determined climate zones throughout North America. We found common variables between certain zones which led us to
engineer James Hardie siding products for specific climates.
The development of these two products is a result of a heavy investment in R&D and our proprietary technology and
manufacturing processes and culminates in the evolution of 7th generation fiber cement – Engineered for Climate.
This guide provides the best practice guidelines for installing the HardieZone product for your zone. Specific details and helpful
hints that pertain to your zones are included in order to facilitate your installation process. If you are unsure about which zone
your job is located in and which HardieZone product and installation instructions to use, then please visit our website at
