Technical Data

Owing to the low emissions characteristics of plywood, the U.S. Department of Housing and Urban Development (HUD) has exempted products formulated exclusively with phenol-formaldehyde resin (glue that holds the sheets of veneer together) from the testing and certification provisions of 24 CFR 3280
"Manufactured Home Construction and Safety Standards". Large-scale chamber testing of plywood (douglas fir and pine) yielded VOC levels (formaldehyde) that were consistently less than 0.05 ppm as per the HUD testing and certification criteria.
