Re: New requirements for HardiePanel® Vertical Siding used in Multifamily and Commercial Applications - Effective September 1, 2013

As an industry leader, James Hardie seeks to ensure that we deliver customer value through the products and services that we offer to the market. As such, we look to keep up with best practices for the use of our products to provide both superior performance and aesthetics. There are some key changes that we would like to bring to your attention:

Rainscreen application for panels - Effective September 1, 2013, James Hardie will require that HardiePanel Vertical Siding is attached over a minimum 3/8" furring to create an air space behind the panel.

To support these changes in the design and installation process, James Hardie has produced two new documents; a Hardie Panel Technical Guide for Multifamily and Commercial Traditional Panel Applications (PDF) and Multifamily/Commercial Installation instructions (HZ5 | HZ10 | HZ5 CANADA). The technical guide document also includes new requirements and limitations for the use of HardiePanel with Colorplus® Technology, further supporting our recent push for the correct application and use of James Hardie touchup kits.

As a result of reviewing customer feedback around the timing we have added further supporting information to help our customers through the transition:
We understand that there will always be exceptions — and not every project will hit the fall timeline — for customers requesting confirmation that warranty will not be affected during the transition specifically for projects that cannot meet the September 1 timeline, a standard letter can be found here.
