Hello Chuck, I can't say with certainty, but it's highly unlikely that plywood would pass the test. I wouldn't expect any wood products to pass tests for use in air handling spaces.

Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> Hi, Happy Holiday's everyone. I'm writing for an opinion or comment on whether a one to two cubic foot square box made of one-half inch thickness hardwood plywood will pass the UL 2043 Fire Test for Heat and Visible Smoke Release for Discrete Products and Their Accessories Installed in Air-Handling Spaces. I am curious about how all-wood boxes perform or lack there-of. Thank you, Chuck McDowell NOTICE: This email may contain confidential information.
