Storage and Handling
•
• Do not place Shiplap directly on a surface that can develop excessive heat
• Store in a cool, dry place
• We recommend storing with pallet covers to keep it clean and protected
• Shiplap are packaged interlocked. Pull boards across the row and not straight down the stack
(see image)
• Acclimate ACRE to the temperature it will be installed at for at least two hours before
processing. During installation, keep ACRE at a consistent temperature
Safety
• Wear safety glasses and appropriate personal protective equipment (PPE) for job site
conditions
• Follow proper safety practices for using all power tools and any job site equipment

FLASHING REQUIREMENTS
•
• Allow ½” clearance between the siding and the roof line
•
•
water getting through the cladding
Expansion and Contraction
• Shiplap siding undergoes a degree of linear expansion with changes in weather or seasons.
• Fasten Shiplap siding as soon after cutting as possible to minimize expansion and contraction.
• Whenever possible, use shorter lengths as splitter / divider boards in continuous runs of
boards.
• For best results, keep boards as cool as possible during attachment. if attaching during high
heat, larger gapping can be expected.
Installation Preparation
BEFORE GETTING STARTED
• Ensure boards are dry before installation
Based on the temperature at
time of installation, see chart.
Create a gap between boards
and follow fastening guidelines.
WALL REQUIREMENTS
• Shiplap siding must be installed over traditional wood framed walls with the studs spaced at
most 16in on center.
• The wall should be sheathed with OSB, minimum 7/16” thick or 1/2” thick plywood.
• Wherever possible, shiplap siding should be fastened directly to the studs.
• Prior to installation. Be sure that wall is structurally sound. Ensure that there are no nails or
screws protruding.
MOISTURE
• Always install a drainable weather-resistant barrier according to local building code
requirements
• Avoid installing product in standing water or areas that can stop water from draining away from
the building
Pro tip: Apply stains or clear coats on the ground before installation.
Coat ACRE with manufacturer recommended water-based paints, stains or sealers.
If you choose to paint ACRE, use a coating with a Light Reective Value (LRV) above 55%.
Pay close attention to our approved coatings for darker colors.

FASTENING
To have fasteners last as long as Shiplap siding, use a high-quality fastener that meets the following
• Using screws for fastening is highly recommended.
• Stainless Steel recommended; alternatively use exterior rated galvanized fasteners
•
•
• 6D or 8D Stainless steel pneumatic ring shank nails may be used as well.
•
• If fasteners are unable to penetrate framing, fasten into OSB no more than 12” apart along
the length of the board
• For a more secure fastening schedule and to mitigate movement, fasten every 12”
•

JOINTS
• For butt joints, ACRE shiplap may be joined together using a shiplap joint. Refer to the
expansion and contraction section above for gap information.
• For long continuous courses of ACRE shiplap or for installations using glued butt joints, leave
1/8” gap into a rabbeted ACRE trim on corners to allow for movement. A scarf joint may be
used for gluing two boards together.
• We recommend glues formulated for PVC products.
HANGING ACRE SHIPLAP HORIZONTALLY
• Stagger butt joints over stud locations to reduce noticeable patterns
• Leave 1/8’’ gap from the board to the edge of the wall into the rabbeted outside corners
• When a course of siding runs underneath a window, fastener every 8”
• Seal all vertical joints along window and door edges with a high-grade exterior caulk
• Shiplap siding can be installed by stacking the siding into the course below
• Starter and end boards require fastening at its face at least 1/2” from the edge
STARTING AND ENDING COURSE FOR HORIZONTAL
INSTALLATION
• Begin by ripping a piece of ACRE shiplap in half lengthwise. Use the top cut as the starter
course and the bottom cut as the end course.
•
•
• Continue the installation as described below
• End the installation with the bottom cut by stacking the board on top of the last course and
face fastening into the wall.
