  6. HardiePlank HardiePlank Lap Siding Product Description Did You Know? • HardiePlank Lap Siding – • HardiePlank lap siding is Factory-Primed Fiber-Cement lap siding available in a variety of style and textures. • HardiePlank lap siding comes in 12’ Lengths. • Nominal widths available in 5 ¼” (primed only) – 6 ¼”, 7 ¼”, 8 ¼”, 9 ¼” (primed only) & 12” (primed only) to create a range of exposures from 4” to 10 ¾”. • HardiePlank lap siding is also available with ColorPlus Technology - James Hardie’s prefinished products. ColorPlus Technology is a factory applied, oven-baked finish available in 20 colors. • The HZ5 Engineered for Climateproduct line is right at home in climates with freezing temperatures, seasonal temperature variations, snow & ice.

  7. HardiePlank Installation of the HardiePlank Lap Siding Did You Know? • HardiePlank Lap Siding – Starter Strip • HardiePlank lap siding REQUIRES a starter strip beneath the first course to establish the proper plank angle, & create a proper drip edge at the bottom of the lap siding. • Starter strips are easily made by ripping 1 ¼” inch pieces of HardiePlank lap siding from full or partial planks, or prefabricated starter strip maybe used. • The Starter strip MUSTbe installed over the water-resistive barrier, but occasional gaps should be left in the starter strip to allow accumulated moisture behind the siding to drain away safely. (When not incorporating a capillary break) • The bottom of the starter strip should be installed even with the bottom edge of the exterior sheathing.

  9. HardiePlank Installation of the HardiePlank Lap Siding Did You Know? INSTALLING THE PLANKS: 3 Key Points The first course of HardiePlank lap siding is critical to the proper installation of the plank on the rest of the building. 3 Key Points to installing HardiePlank lap siding: The first course should start at the lowest point of the building. The first course must be installed straight and level. Make sure to stagger all butt joints in the HardiePlank so that the installation is attractive while making efficient use of material.

  10. HardiePlank STAGGERING THE BUTT JOINTS: For walls longer than 12’ it is necessary to butt joint additional lengths of HardiePlank siding. These butt joints should be staggered to avoid noticeable patterns, which is determined by the placement of the first course. Butt joints between consecutive courses should be spaced apart by at least two stud bays for 16” o.c framing or one stud bay for 24” o.c framing. Keys to Staggering the Butt Joints: While random placement of the planks is usually the most aesthetically pleasing, a progressive stagger pattern can make the job easier and faster without the pattern becoming too noticeable. With this strategy, the cut off pieces for one course becomes the starter piece for a course above, making efficient use of materials and ensuring that all butt joints land on studs. The pattern can be modified for different stud placement.

  13. HardiePlank Installation of the HardiePlank Lap Siding Did You Know? The bottom of the lap siding should be kept even with the bottom of the trim, or if desired, the trim may extend below the bottom of the siding. The siding must never hang below the trim. When installing the first course make sure ground clearances are in accordance with James Hardie requirements and those of local building codes. Typically 8” of clearance is required. PLANK ALIGNMENT AT THE CORNERS: Make sure the HardiePlank bottom edges match from elevation to elevation around the corners. Use a Framing Square, Speed Square, or a Level to ensure both elevation line up around the corners. Check every few courses to ensure that your layout and reveal are lining up. Remember to always leave a min. 1/8” caulking gap between the HardiePlank and the Trim to allow for proper caulking application.

  15. HardiePlank Installation of the HardiePlank Lap Siding Did You Know? IMPORTANT: To prevent damage to the drip edge, extra care should be taken when removing planks from the pallet, while handling, and when installing with a lap gauge. Planks are interlocked together on the pallet, therefore they should be removed from the pallet horizontally (side to side) to allow planks to unlock themselves from one another.

  16. HardiePlank Blind Nailing is recommended for installing any type of HardiePlank lap siding including ColorPlus siding. With Blind Nailing, each course covers the fasteners on the course below, which provides a better looking installation. BLIND NAILING: (Nailing Through the Top of Plank) Place fasteners an 1 1/8” from the top edge of the plank. Additionally fasteners should be placed no closer than 3/8” from the ends of the plank. HardiePlank HZ5 lap siding is manufactured with a nail line that should be used as a guide for proper nail placement when blind nailing. This nail line should NOT be used as a lap line. Avoid placing fasteners near the top edge of the plank. This practice, called “high nailing”, may lead to loose planks, unwanted gaps or rattling. Pinning of Butt Joints with a finish nail may be done for aesthetic purposes only. The finish nail should be nailed flush to the surface (not countersunk), must be fully corrosion resistant (e.g. galvanized or stainless) and does NOTprovide any structural support.

  17. HardiePlank Installation of the HardiePlank Lap Siding Did You Know? JOINT FLASHING: The recommended method for butting factory-finish ends for all HardiePlank lap siding is moderate contact over a piece of joint flashing. This method is required for joining ColorPlus lap siding products. JOINT FLASHING: Requirements Joint Flashing must be 6” wide that overlaps the course below by 1”(3” on either side of the butt joint) Joint-flashing material must be durable, waterproof materialthat does notreact with cement products. Suitable material includes finished coil stock and code compliant water-resistive barriers. Other products may also be suitable. Joint Flashing is Required with ColorPlus HardiePlank. Joint Flashing is recommended with PrimePlus HardiePlank without voiding the warranty. *Refer to Appendix for more information.

  19. HardiePlank Continuing the Installation of the HardiePlank Lap Siding • Once the initial course of HardiePlank lap siding is fastened to the wall, continue installing successive courses with full 12’ pieces (follow the stagger pattern for longer walls), or until a window, door or other opening interrupts the course (fig 9.12). • Notch planks as needed to fit around windows and doors. Again, be sure to paint or prime ALL cut edges. Avoid placing butt joints directly above or below windows or above doors. • Separate the joints from the opening by at least one course of lap siding. • Where butt joint joints land on a stud, make sure there is enough stud space for plank on both sides of the joints to land properly. Optimally both sides of a butt joint should land in the middle of a stud with ¾” landing space for each side. The minimum stud space for a plank to land is 3/8”

  20. HardiePlank Installation of the HardiePlank Lap Siding on a Gable Siding gable walls can be challenging, and some of the keys to siding gable walls efficiently are determining the angle or pitch of the roof, properly staging materials, and ensuring that the plank lengths are measured accurately. To Estimate the amount of siding needed to complete a gable end, use the estimating tools located in Appendix B. To Cut Planks for the Gable: Tack up a small scrap piece of siding where the first gable course is going. Hold a second small piece of siding against the eave or rake board. Trace the angle onto the scrap piece. Cut that line and label the scrap as the template for that gable angle. The template can then be used to transfer the angle onto the larger pieces for cutting and installation. Periodically check the angle as you progress up the wall.

  21. HardiePlank Recommended Fasteners for HardiePlank Lap Siding Fastener Specifications: The standard fastener for HardiePlank is a 0.89” x .221” x 2” corrosion resistant siding nail. A Roofing Nail will increase the windload rating by 40 to 50 MPH and is rated to hold in just 7/16” OSB or ½” APA rated Plywood.
