  6. HardiePanel HardiePanel Vertical Siding Installation - Getting Started - First Locate the Lowest Point of the Sheathing or Sill Plate, and Begin Installation on that Wall. 16”-in. oc Measure up from the sill plate the height of the panel at either end of the wall - snap a straight, level chalk line between the marks as a reference line. That line is for guidance in positioning the top edge of the panels. Check the reference line with a min. 4’-ft level. TIP: Verify Wind Load Requirements for Fastener Spacing – ESR-1844. Starting on one end and working across the wall, measure and trim the first panel making sure that the edge falls in the middle of a stud. 8”-in. oc Position the panels top edge on the chalk line and secure it with suitable fasteners and fastener spacing for the particular application as noted in the ESR-1844 Report. As installation continues, check the vertical edge of each panel with a min. 4’-ft. level to ensure panels are plumb & level. TIP: For Sierra 8 Panels, Double Studs are Required at Each Vert. Joint. TIP: Blue chalk is Recommended because it washes off. DO NOT use Red or Black chalkthey are considered permanent and may bleed through lighter colored paints. TIP: Install Flashing Over the Footing/Foundation & Extend the Panel Over the Flashing just below the Sill Plate. Do Not Extend Siding Beyond the Required Grade Clearance.

  7. HardiePanel HardiePanel Vertical Siding Installation Did You Know? Vertical Joint Treatment – All Vertical Joints in HardiePanel Vertical Siding MUST be treated using one of the following Four Joint Treatments: Install the Panels in Moderate Contact with Joint Flashing. Joint Flashing is typically a 6”-in. strip of weather resistant barrier (house wrap). Leave an 1/8” inch gap between Panels and fill with caulk. Caulking MUST be a high quality paintable, permanently flexible caulking that meets ASTM C-834 or C-920 Requirements. TIP: As an option, install the first panel and apply a bead of caulk along the vert. panel edge. Install the next panel against the first, making sure to embed the edge in the applied caulk creating a thorough seal between the edges of the two panels.

  8. HardiePanel HardiePanel Vertical Siding Installation Did You Know? Vertical Joint Treatment – Continued All Vertical Joints in HardiePanel Vertical Siding MUST be treated using one of the following Four Joint Treatments: Vertical Jointsmay be Covered with Wood or Fiber Cement Batten Strips. Batten Strips MUSTSpan the Vertical Joint by at least ¾”-in. on each side. Metal or PVC “H” Moldings can be used to Join Two Vertical Sections of HardiePanel Siding.

  9. Recommended Fasteners -HardiePanel – Traditional Design Battened Vertical Joint Moderate Contact Vertical Joint Trimmed Vertical Joint • Fastener Requirements • Utilize fasteners and fastener spacing as prescribed in the HardiePanel installation instructions and the ESR-1844 or as governed by code. • Do not countersink or overdrive fasteners. Fasteners shall be flush with panel surface. • For Traditional Design HardiePanel - Fastening into wood - use the recommended Nail.

  13. HardiePanel HardiePanel Vertical Siding Installation - Horizontal Joint Treatment - NOTE: ALL Horizontal Flashing MUST be Cut-In Behind the (WRB) Water-Resistive Barrier. In some applications such as multi-story structures or at gable ends, it may be necessary to stack HardiePanel siding. ALLHorizontal Joints created Between Panels MUST be Flashed Properly to Minimize Water Penetration. Treat Horizontal Panel Joints by using one of the Following Methods: • After Installing the Lower Course of Panel Siding, Install Vinyl, Coated Aluminum, or Coated Steel “Z” Flashing at the Top Edge of the Panel. NOTE: ALL Horizontal Flashing MUST be Installed with Positive Slope - Sloping Away from the Building & NOT Sitting Flat on the Top Edge of the HardiePanel • Install the Second Course or gable panels Leaving a ¼”-in. Minimum Gapbetween the Bottom of the Paneland the “Z” Flashing. (This Gap Should NEVER be Caulked.) • As an Alternative, if a Horizontal Band Board is used at the Horizontal Joint, FlashingMUSTExtend Over the Panel Edge & Trim Attachment. Min. 15o Positive Slope

  14. HardiePanel HardiePanel Vertical Siding Installation - Layout Options - Item #1: Center Panel Out When Laying Out your HardiePanel Installation, there are Two (2) Layout Options. These Two (2) Layout Optionsare: For the Most SymmetricalLook, Plan the Installation so that a Full Panelis Centered on the Wall or Gable with Equal-Size Panels Cut for Each End. TIP: These strategies might entail a center-out framing layout. Item #2: Center Seam Out TIP: Choose the strategy that looks the best and uses material the most efficiently. As an Alternative – Plan the Installation so that a Full Panelis located on Either Side of the Walls Center Line. leaving Equal Size Panels on Each End.

  15. HardiePanel HardiePanel Vertical Siding Installation - Windows, Doors, & Other Wall Penetrations - In Panel Installations, Trim is Typically Overlaid on Top of the Panels. Special Attention needs to be paid to Trim Flashing at the Tops of the Openings. Below is One Method for Properly Flashing Trim in a Panel Application: 1– Install ¼”-in. thick Shim Over the Window Flashing After Installing the Window, Cut and Install a ¼”-in. Thick Shimabove the Window. The Shim should be the Same Heightas the Trim, but only as Long as the Width of the Window. Over the Shim - Install Flashing(wide enough to cover the thickness of the trim & long enough to cover the window head trim.) Shim 2 – Install Flashing Over the Shim & Under the Water-Resistive Barrier. Finished Installation

  16. HardiePanel HardiePanel Vertical Siding Installation - Windows, Doors, & Other Wall Penetrations - Installation Continued… Install the Trim around the Windows, Slipping the Head Piece Under the Installed Flashing. Install the Panel to the Window & Around the Shim(taking care not to damage the flashing). Leave a Min. ¼”-in. Gap between the Panel & the Horizontal Part of the Flashing. 4 – Install Window Trim Under the Flashing 3 – Cut & Fit Panel around the Shim & Flashing – Leave Min. ¼”-in. Gap Between the Flashing & the Upper Panel Edge. Cut & Fit HardiePanel

  17. HardiePanel HardiePanel Vertical Siding Installation - Rain Screens - 6” Reinforced Mesh Bug Screen Installation of HardiePanel Over Furring - • Rainscreen Requirements: • James Hardie REQUIRES a minimum 3/8” drained & ventilated cavity, to serve as a capillary break, in the application of Multifamily and Commercial Construction. .089” x .221” x 2” Siding Nail • The Capillary Break shall be installed between the Cladding and Code Approved (WRB) water-resistive barrier. • Furring Fasteners MUSTbe designed to Support Cladding Weight. ½” x 1.5” Pressure Treated Plywood Strapping (Furring) • FurringMUST be Attached Vertically and MUST be Adequately Fastened to the Structural Framing with a suitable fastener. • Furring shall be a minimum 3/8” thick and sized to provide adequate substrate to cladding connection; a nominal 1.5” in width would be the minimum. TIP: James Hardie Does NOT Recommend Drainage Mats or Drainage Boards in this Application. Rainscreen Strapping (Furring) Installed @ 16”-in. OC Double Up the Strapping (Furring) @ Trim Locations

  18. HardiePanel HardiePanel Vertical Siding Installation - Rain Screens - Installation of HardiePanel Over Furring - • Fastener Requirements: • When installing James Hardie Siding Products over furring the question arises what thickness of furring can be used as an alternate to normal metal or wood studs specified in the ESR-1844 & 2290 Report? • General Rule of Thumb is, the specific ESR-1844 & 2290 fastener must be installed into material that has the same or better holding power than that specified in the ESR-1844 &2290 and the same penetration as the ESR-1844 & 2290 fastener. Rainscreen Strapping (Furring) Installed @ 16”-in. OC Double Up the Strapping (Furring) @ Trim Locations
