Composite Wood Evaluation. Composite wood, as defined by the California Air Resources Board, Airborne Toxic Measure to Reduce Formaldehyde Emissions from Composite Wood Products Regulation, must be documented to have low formaldehyde emissions that meet the California Air Resources Board ATCM for formaldehyde requirements for ultra-low-emitting formaldehyde (ULEF) resins or no added formaldehyde resins.
The LEED v4 requirement for composite wood panels is that they meet California Air Resources Board Ultra Low Emitting (CARB ULEF) or No Added Formaldehyde (NAF) resin requirements. HPL is NOT a composite wood panel, even though it does contain paper which is derived from wood. Unfortunately, this is a common misunderstanding concerning HPL. Since HPL has low emissions of Volatile Organic Compounds (VOCs) and is NOT a Composite Wood Panel, it is EXEMPT from both the California Air Resources Board (CARB) and the EPA Composite Wood Rule. Most HPL product types may qualify as an individual component in a system or part of finished product or furniture; depending upon the LEED credit approach used. As a laminate Wilsonart HPL is exempt from reporting NAUF content. NAUF certification needs to be requested from the manufacturer of the finished article who will include the substrate (wood panel), adhesive, HPL decorative surface, backer, edge banding and other components into a certification for the finished product.
Wilsonart TFL panels are available with a ULEF or NAUF substrate and certifications are available upon request. Please contact a Wilsonart Sales Representative, Customer Service Representative or call the Wilsonart Customer Service Hotline at 800-433-3222.
