Introduction

The material contained herein provides installation guidelines for the Hardie® Architectural Panel System by James Hardie. This document is intended for use by builders, cladding installers, and other contractors who may be involved with the installation of the Hardie® Architectural Panel System.
Before you begin your siding project read the instruction manual completely and thoroughly. This document describes and illustrates the minimum steps required to install the Hardie® Architectural Panel System. No instruction manual can anticipate every condition, circumstance, or situation that might arise during installation over the course of the project. When in doubt about assembly details, contact the architect, specifier, or a building official. Contact your James Hardie Sales and Install Representative for product support 1-800-9HARDIE (1- 800-942-7343).
PREPARATION
Ensure the drainage plane is intact and all penetrations are sealed. Plan your work, use the proper tools, techniques, and follow installation procedures as covered in this installation manual. It is important that builders, specifiers, and installers recognize requirements and information pertaining to:

• Safety
• Storage and Handling
• Cutting
• Wall Preparation
• Fastening

For best results, before installation, ensure your panels are clean and free of dirt, dust, chalking, oil, grease, organic contaminants, or mold. Dust from cutting and construction should be removed immediately upon installation.
PRACTICE INSTALLING MATERIAL
Utilize a mock-up to evaluate installation and finishing techniques, with a focus on specific applications designed by a design professional or engineer. The fastening practice and/or fastening tools shall be properly adjusted to avoid overdriving. Do not proceed with remaining work until workmanship, color, and sheen are approved. Repeat mock-up area as required to produce acceptable work.

Safe Working Practices

STORAGE & HANDLING
Store flat and keep dry and covered prior to installation. Installing siding wet or saturated may result in shrinkage. Protect edges and corners from breakage. James Hardie is not responsible for damage caused by improper storage and handling of the product.

CUTTING INSTRUCTIONS
OUTDOORS

1. Position cutting station so that airflow blows dust away from the user and others near the cutting area.
2. Cut using one of the following methods based on jobsite requirements:
   a. Best: Circular saw equipped with a HardieBlade® saw blade and attached vacuum dust collection system.
   b. Shears (manual, pneumatic or electric) or the score and snap method may also be used.
   c. Better: Circular saw equipped with a dust collection feature and a HardieBlade® saw blade.
   d. Good: Circular saw equipped with a HardieBlade® saw blade.

INDOORS

1. NEVER grind or cut with a power saw indoors.
2. Cut only using shears (manual, pneumatic or electric) or the score and snap method.

GENERAL

• During clean-up of dust and debris, wet dust and debris down with a fine water mist, apply a dust reducing sweeping compound in sufficient quantities, or use a vacuum to collect dust and debris. DO NOT use compressed air.
  DO NOT dry sweep without first applying a dust reducing control measure.

• For best performance when cutting with a circular saw, James Hardie recommends using HardieBlade® saw blades.

• Go to jameshardiepros.com for additional cutting and dust control recommendations.

IMPORTANT: The Occupational Safety and Health Administration (OSHA) regulates workplace exposure to silica dust. For construction sites, OSHA has deemed that cutting fiber cement with a circular saw having a blade diameter less than 8 inches and connected to a commercially available dust collection system per manufacturer’s instructions results in exposures below the OSHA Permissible Exposure Limit (PEL) for respirable crystalline silica, without the need for additional respiratory protection.
If you are unsure about how to comply with OSHA silica dust regulations, consult a qualified industrial hygienist or safety professional, or contact your James Hardie technical sales representative for assistance. James Hardie makes no representation or warranty that adopting a particular cutting practice will assure your compliance with OSHA rules or other applicable laws and safety requirements.
HANDLING PANELS
When handling Hardie® Architectural Panels care should be given to prevent damage to the machined edges and/or the ColorPlus finish.

• Utilize 2 persons to carry product.
• Carry panels along the long edges whenever possible (Fig. 2a).
• When handling panels on short edges and the need to set down, place with the underlap edge of the shiplap facing down. (tongue/long edge) (Fig. 2b).
  Doing so will:
  – Prevent damage to top edge (visible edge) of panel if dropped or dragged.
  – Help prevent scratches to ColorPlus finish.

ColorPlus Tip:

• When possible, carry with plastic covering in place. This will help to protect the ColorPlus finish.
• Wearing gloves will help prevent fingerprint smudges to the ColorPlus finish

CUT STATION & CUTTING
Setup cutting station (Fig. 2c), and locate close to installation area.
TIP: Utilize the pallet & cardboard toppers to create your cutting table
Use a HardieBlade® to cut James Hardie fiber cement products. A track saw with vacuum system (Fig. 2d) is best for cutting Hardie® Architectural Panels.
a. Cleaner cuts
b. Panels can be cut facing up (minimize panel movements)
c. If using a traditional circular saw with vacuum system, place panel face down to prevent marring of the finished surface caused by friction from the saw.

ColorPlus Tip:

• A scratch proof platform is a good idea to prevent from scratching the ColorPlus surface while cutting. The cardboard cover from the top of the pallet makes a great non marking surface.
• Keep a spray bottle (filled with water) and soft cloths to wipe cut dust off immediately after cutting to keep your ColorPlus finish looking fresh.
• Touch-up all cut edges

Design & Fastener Aesthetics

PANEL JOINT CONSIDERATIONS

FASTENING GUIDELINES
The following guidelines should be followed to achieve the desired aesthetics from the fastening of stainless steel finish nails to attach Hardie® Architectural Panels:

1. In-Line Regulator (Fig. 13)
   a. Control variable air supply from compressor
   b. 75-90 psi (average setting) if difficulty maintaining psi and/or depth control, check nailer for wear and replace or repair accordingly

2. No-Mar Tips (fig.14)
   a. Avoid surface damage
   b. Depth control

3. Gun angle to wall (fig. 15)

4. Nails should be left proud, then tapped flush immediately with a smooth face hammer

5. Do Not over drive fasteners
   a. Will appear after painting
   b. Will increase need for patching & touch-up

6. Test nail depth on scrap prior to panel installation

GENERAL
Finish nails must be stainless steel. Fasteners must be corrosion resistant, galvanized, or stainless steel. Electro-galvanized are acceptable but may exhibit premature corrosion. Unless otherwise directed, James Hardie recommends the use of quality, hot-dipped galvanized nails. James Hardie is not responsible for the corrosion resistance of fasteners.
Stainless steel fasteners are recommended when installing James Hardie® products near the ocean, large bodies of water, or in very humid climates. Note: Ring shank (not smooth) shall be used when specifying stainless steel nails.
Manufacturers of ACQ and CA preservative-treated wood recommend spacer materials or other physical barriers to prevent direct contact of ACQ or CA preservative-treated wood and aluminium products. Fasteners used to attach HardieTrim Tabs, aluminium trim, or flashing to preservative treated wood shall be of hot dipped zinc-coated galvanized steel or stainless steel and in accordance to the latest versions of the IRC/IBC.

• Consult applicable product evaluation or listing for correct fasteners type and placement to achieve specified design wind loads.
• NOTE: Published wind loads may not be applicable to all areas where Local Building Codes have specific jurisdiction. Consult James Hardie Technical Services if you are unsure of applicable compliance documentation.
• Drive fasteners perpendicular to siding and framing.
• Fastener heads should fit snug against siding (no air space).

PNEUMATIC FASTENING
James Hardie® products can be hand nailed or fastened with a pneumatic tool. Pneumatic fastening is highly recommended. Set air pressure so that the fastener is driven snug with the surface of the siding. A flush mount attachment on the pneumatic tool is recommended. This will help control the depth the nail is driven. If setting the nail depth proves difficult, choose a setting that under drives the nail. (Drive under driven nails snug with a smooth faced hammer – Does not apply for installation to steel framing).
COLORPLUS FASTENERS
Color matched stainless steel finish nails are available for Hardie® Architectural Panels with ColorPlus technology Nails installed the same as described above. Touch- up fasteners as needed using the touch applicator brush Fig.16

Finish Nail *Use a smooth face hammer and lightly tap flush.
Tips: for fastener depth control:

1. Installation must be in accordance with manufacturer’s installation instructions
2. Building heights are the mean roof height (ft) of a building except the eave height shall be used for the roof angles of less than or equal to 10° (2-12 roof slope)
3. Linear interpolation of building height (≤ 60ft) and wind speed is permitted.
4. Wind speed design coefficient assumptions per Analytical Method in ASCE 7-05: I=1, Kzt=1, Kd=0.85, GCp= -1.4, GCpi= -0.18
5. Wind speed design assumptions per Analytical Method in ASCE 7-10 &ACE 7-16 Section 30.4: Kzt=1, Kd=0.85, GCp= -1.4, GCpi= 0.18
6. Wood framing species must have a specific gravity of 0.42 gravity or higher.
7. Wood framing species must have a specific gravity of 0.46 gravity or higher.
8. Wood Structural Sheathing panel must have a specific gravity of 0.50 or higher.
9. Vult = ultimate design wind speed.
10. Vasd = nominal design wind speed.
11. V = basic design wind speed
12. Basic Design Wind Speed per ASCE 7-16 or 2017 FBC/2018 IBC Figures 1609.3(1) through 1609.3(8). Where design is based on the fastest mile wind speeds, the basic wind speed shall be converted to the fastest mile wind speed Vfm per Section R301.2.1.3 of the 2012 IRC.
13. 2017 & 2020 FBC, 2018 IBC Section 1609.3.1 Eq. 16-33, Vasd = Vult (0.6)⁰.⁵
14. The NDS published specific gravities of SPF lumber & Wood Structural Panel (WSP) furring are 0.42 and 0.50 respectively. Attachment of the furring to the structural framing must be determine by the project design engineer to resist the allowable design wind loads for the maximum wind speeds as tabulated.

Other marks or registered emarks or service marks are the property of their respective owners. DANGER: May cause cancer if dust from product is inhaled. Causes damage to lungs and respiratory system through prolonged or repeated inhalation of dust from product. Refer to the current product Safety Data Sheet before use. The hazard associated with fiber cement arises from crystalline silica present in the dust generated by activities such as cutting, machining, drilling, routing, sawing, crushing, or otherwise abrading fiber cement, and when cleaning up, disposing of or moving the dust. When doing any of these activities in a manner that generates dust you must (1) comply with the OSHA standard for silica dust and/or other applicable law, (2) follow James Hardie cutting instructions to reduce or limit the release of dust; (3) warn others in the area to avoid breathing the dust; (4) when using mechanical saw or high speed cutting tools, work outdoors and use dust collection equipment; and (5) if no other dust controls are available, wear a dust mask or respirator that meets NIOSH requirements (e.g. N-95 dust mask). During clean-up, use a well maintained vacuum and filter appropriate for capturing fine (respirable) dust or use wet clean-up methods – never dry sweep.
WARNING: This product can expose you to chemicals including respirable crystalline silica, which is known to the State of California to cause cancer. For more information go to P65Warnings.ca.gov.
