The combination of AlluraTM Fiber Cement vertical siding and the Easytrim RevealsTM aluminum architectural extrusion enables architects to execute unique exterior wall designs that blend contemporary aesthetics with fiber cement’s significant long-term performance and sustainability.

For architects looking to increase the aesthetic appeal of the product by reducing the number of fasteners required to attach the vertical siding to the wall surface, Allura suggests the following fastening pattern alternatives.

When installing Allura Fiber Cement vertical siding with Easytrim Reveal horizontal trim pieces, please adhere to the following recommendations:

• Allura Fiber Cement vertical siding panels are approved for and should be set directly on top of the following Easytrims Reveals horizontal trim pieces. Note: Horizontal trim to be fastened to framing no greater than 24” on center.

• DO NOT CAULK Horizontal Z or H Reveals

Fastening options for Allura Fiber Cement Vertical Siding when used with the Easytrim Reveals Aluminum Wall System

• When Fiber Cement siding panels are set directly on top of Easytrims Reveals horizontal trim pieces, an unmodified factory edge is required and must be used. All cut edges of fiber cement siding panels must be primed or painted to prevent water absorption and potential delamination.

• As noted in the Allura Fiber Cement Installation Manual, a 1/8” gap should be maintained where the sides and top of the fiber cement siding panels align with the Easytrims Reveals horizontal trim pieces.

Note: Not all EZTrim profiles are shown.

* Windload performance information on these alternative fastening patterns can be obtained through your Allura territory manager.Also see ES-ESR-1668 report for windload values for A and B patterns

(Important note: Geographic location and specific design parameters must be accounted for when determining the optimum fastening pattern for a particular project.)

Installing WeatherBoards Fiber Cement siding panels and Easytrim Reveals horizontal trim pieces using screws.

Using screws with the Easytrims Reveals system greatly reduces the number of required fasteners compared to nailing. Pre-drilling the fastener holes provides several advantages: maximized panel strength, consistent fastener placement and superior aesthetics.

When installing WeatherBoards Fiber Cement siding panels using Easytrims Reveals horizontal trim pieces, CertainTeed highly recommends 300 series austenitic steel cladding fasteners by SFS Intec, Inc. (see below).

Important Information

• All products must be installed in accordance with all national, state and local building codes. Be sure to check with your local code official or governing body for the building requirements in your area.

• All other installation requirements listed in the CertainTeed WeatherBoards Fiber Cement Siding Installation Manual (FC017) must be met.

• Failure to comply with CertainTeed installation instructions and/or applicable building codes may affect product performance and void the product warranty.

• Refer to the EasyTrim Reveals website (www.easytrimreveals.com) for specific reveal installation and fastening requirements.

• Cladding systems that incorporate reveal trim used with fiber cement siding panels are designed to provide a modern architectural look while delivering an aesthetically pleasing appearance. When using reveal systems, cladding system design becomes a prescriptive approach based on many factors including wall system construction, and fastening requirements for the siding depend on the specific wall system design. When incorporating CertainTeed WeatherBoards Fiber Cement siding into a reveal cladding system, adhere to the recommendations and requirements contained in this document, the latest version of the WeatherBoards Installation Manual (FC017), the installation instructions provided by the trim reveal system manufacturer, as well as all national, state and local building codes. The ultimate responsibility for cladding system design is the responsibility of the general contractor, architect/designer, building engineer and/or contractor. CertainTeed will not accept any liability or responsibility for cladding system design or for any product failure caused by application that does not meet the requirements for proper installation.
