Installation Instructions

Staggered Edge
6
• Siding may be installed directly to studs spaced no greater than 16” (406 mm) o.c. that have adequate corner bracing.
• Use a minimum 0.092 inch diameter smooth shank nail, hot-dipped galvanized (ASTM A153) or equivalent. Fasteners
shall be corrosion resistant and capable of preventing rust, stain and deterioration under normal outdoor environmental
conditions for a period of no less than 50 years.
• Fastener placement: A minimum 3/4 inch (19 mm) down from top edge of siding. Do not place fastener through top
shiplap, place fastener 1 inch (25 mm) from end. (Diagram 6b) Place fastener into bottom shiplap a minimum 3/4 inch
(19 mm) down from top edge of siding. (Diagram 6b)
• Fastener length: Long enough to fully penetrate studs by 1-1/2 inch (38 mm). (Diagram 6b)
• Fastener spacing: Space ring shank nails a maximum of 16 inches (406 mm) o.c. across the top of siding. (Diagram 6a)
• Begin by nailing a starter strip approximately 3/8 inch (10 mm) thick x 1-1/2 inches (38 mm) wide  ush with bottom edge of
sill plate.
• Staggered Edge: Starting from left to right, level and install shake so bottom edge is no more than 1/2 inch (13 mm) below
the starter strip, or
• Straight Edge: Starting from right to left, level and install shake so bottom edge is no more than 1/2 inch (13 mm) below the
starter strip.
• Use the alignment groove in shiplap edge as a spacing guide. Do not overlap the alignment groove.
• Use the alignment groove in shiplap edge as a spacing guide. Do not overlap the alignment groove.

- Alternate reveals are allowed. Trim should be thick enough so the shake does not extend beyond its face.
- Alternate reveals are allowed. Trim should be thick enough so the shake does not extend beyond its face.
•
• To obtain staggered edge appearance, cut and fasten starter pieces for each course using a 16 inch (406 mm) stair-step
method as shown in
(Diagrams 6a)
(Diagrams 6a).
•
• To obtain straight edge appearance, rotate shake siding drip edge 180 degrees, cut and fasten starter pieces for each course
using a 16 inch (406 mm) stair-step method.
•
• Overlap shakes using the alignment notch to conceal nail heads and achieve uniform reveal. The alignment notch provides
for an overlap of at least 1 inch (25 mm) at the shortest staggered edge to a maximum of 1-3/4 inches (45 mm) at the longest
staggered edge regardless of whether the staggered or straight edge is exposed.
• The shake should  t against the window/door trim or the corner board leaving a 3/16 inch (5 mm) space.
- Shiplap at this location must be removed to full panel thickness and caulked.
- The opposite shiplap edge is facing up, to receive the next piece of siding.
• When fastening direct to stud, every other shake line (or keyway) will fall in line with the shake lines on the courses above
and below. (Diagram 6a)
