Are PureBond Formaldehyde-Free Hardwood Plywood panels fire rated?
Our standard PureBond veneer core plywood meets a Class C Flame Spread rating as described in the Fire Safety Code. Most untreated wood products meet Class C. Our PureBond® veneer core panels are not treated with a fire retardant and are not available with a Class A rating. Class A core (required by some building codes) may be available for manufacture into a no added urea-formaldehyde (NAUF) panel using either fire-rated particleboard or fire-rated MDF. The Class A rating is not affected as long as the veneer on either side does not exceed 1/28″, which ours usually do not. These cores also carry minimum volume requirements and lead times come into play. When manufactured with our formaldehyde-free, soy based adhesive these panels are compliant with LEED credit EQ 4.4 and are part of our PureBond® product line.
