Kirei Board: A beautiful natural material made with renewable, non-toxic components. Strong, lightweight and environmentally friendly, Kirei Board is an easily worked engineered panel product usable in nearly any architectural application:
ENVIRONMENTAL BENEFITS
Kirei Board reduces forest clear-cutting, air pollution and landfill use. The sorghum stalks used in the manufacture of Kirei Board are a rapidly renewable resource left after the edible portion of the plant is harvested.
REDUCED WASTE
Until now, these stalks have been discarded or burned, adding to landfill waste and pollution. Kirei Board helps reduce this waste and ease deforestation by substituting for wood. In addition, Kirei Board is made using a non-toxic adhesive that does not contain formalin, helping reduce toxic formaldehyde VOC’s released into the ambient indoor air.
Kirei Board can be an excellent way to help your projects qualify for LEED credit for environmentally friendly construction.

Kirei Board and LEED®
LEED (Leadership in Energy and Environmental Design) Green Building Rating System® is a voluntary, consensus-based national standard for developing high performance, sustainable buildings.
Kirei Board is made from rapidly renewable, reclaimed agricultural fiber, with a low-VOC emission adhesive. While LEED does not certify materials, Kirei Board can help your projects gain credit toward LEED Certification.

Kirei Board is machinable using standard fabricating techniques applicable for woodbased products.
Cutting:
For best results use a high-quality saw blade, feeding the material at a uniform speed through the saw. Solidly back panels to prevent chipping along kerf on the saw tooth exit side. Finishing material with a sealer coat can help avoid chipping along saw cuts.
Drilling:
A high-speed drill is recommended. To avoid chipout or breakage on the exit side, back
the panel with scrap material.
Routing:
A speed of 20,000 RPM is recommended using double-fluted router bits.
Filling:
Standard wood putty can be used to fill any chips or holes caused by cutting and sanding. Select a color that best matches the color of Kirei Board or your finish color.
Fastening:
All fastening methods may be used, including nail, staples, rivets, screws, bolts, glue or
combination. Type A or AB, sheet metal, twin fast types and fully threaded screws designed for use in particle board offer better withdrawal resistance than wood screws.
Pre-drilled pilot holes are recommended for the size screw used. If nailing, use spiral or
ring shank nails for extra holding power.
(Note: Nailing or screwing into edge grain may result in lower screw holding power due
to fewer cross-layers being engaged.)
Finishing:
Kirei Board panels can be filled, sealed, painted, stained or varnished with most commercial finishing materials including short and medium oil length primers, fillers, lacquers, and synthetic base coats and topcoats and high temperature bake and acrylic and epoxy systems. The panels should be at stable room temperature (70 degrees F and higher) when coated. Kirei recommends Low-VOC emission finishes.
Edge Treatment:
The exposed edges of Kirei Board are intended to be finished, unless the type of application does not require a more finished appearance than sanding affords. If shaped exposed edges are required, filling, sanding and painting of the edge will provide a satisfactory finish. Kirei Board can be edge banded with most commercial edge treatments using standard adhesives.
Kirei Board Adhesive
KIREI board is manufactured using KR Bond, a water-based polymer-isocyanate adhesive. Formaldehyde-free KR Bond does not contribute harmful Volatile Organic Compounds (VOCs) to the indoor atmosphere. Testing according to Japanese Government standard JIS A 6922-2003 r esulted in 0.0 mg/L formaldehyde emission
