Hardie Panel is the flat sheet of the range: fibre cement, 5/16 inch thick and four feet wide, in 8, 9 and 10 foot lengths. It covers a wall fast and it is the base of almost every Hardie board and batten you see, because the moment Hardie Trim Batten goes over the seams, a plain vertical panel becomes the modern farmhouse wall. There are four faces. Smooth is flat and paint-like. Select Cedarmill is embossed with a vertical cedar grain. Stucco has the trowelled look of stucco without a stucco crack in it. Sierra 8 has vertical grooves cut into the face, which is why the instructions suggest doubling the stud at panel joints so the nails do not land in a groove.
Smooth and Select Cedarmill are the two you can buy prefinished, in all 19 Statement Collection colours with the ColorPlus finish baked on at the plant, in 4x8 and 4x10. Every texture also comes primed, including a 4x9 that the ColorPlus line does not offer. The installation detail that matters most is behind the panel, not on it. HardiePanel HZ5 is listed in CCMC Evaluation Report 12678-R, and the report requires it to be installed in all areas over wood strapping that creates a drained and vented air space at least 10 mm deep, with vertical joints landing on studs. The single family instructions from James Hardie only recommend a rainscreen, so if you are pricing a job, price the strapping.

Vertical wall applications only. Not for fascia or trim
CCMC 12678-R: install over wood strapping that creates a drained and vented air space not less than 10 mm deep, in all areas. On multi-family and commercial work James Hardie also requires a 3/8 in. capillary break
Studs at a maximum 610 mm (24 in.) o.c., wood or 20 ga to 16 ga steel. Vertical joints must land on a stud
Fasteners 9.5 mm (3/8 in.) from panel edges and no closer than 50 mm (2 in.) to corners. Do not nail into the corners
Sierra 8: double the stud at panel joints so fasteners stay out of the grooves, and line the grooves up from one storey to the next
Vertical joints: moderate contact, a batten, an H moulding, or a caulked 3 mm (1/8 in.) gap (not on ColorPlus®)
Horizontal joints: Z-flashing sloped away with a 6 mm (1/4 in.) gap above it, never caulked. Do not bridge floors
Clearances: 200 mm (8 in.) to finished grade, 50 mm (2 in.) to roofing, decks, slabs and paths
Minimum panel piece 12 x 16 in. Maximum mean roof height 25.9 m (85 ft.)
CCMC 12678-R's opinion covers the uncoated board. Primed and ColorPlus® coatings follow James Hardie's own recommendations
ColorPlus®: exposed fasteners or battens are the recommended application. On Smooth ColorPlus® do not touch up over fastener heads (use primed Smooth where fasteners must be hidden). Touch-up over fasteners is acceptable on Cedarmill ColorPlus®
Fasteners must be corrosion resistant. Hot-dipped galvanized is recommended, and stainless steel near the ocean, large bodies of water or in very humid conditions
Drive fasteners perpendicular and snug. Do not over drive, under drive or angle them, and do not use aluminum fasteners, staples to the wall, or clipped head nails
