Glossary of Wood Terms
We’ve updated our “Definition of Terms” page and renamed it “Glossary of Wood Terms.” We’ve tried to include some of the most commonly used, and in some cases, most confusing, terms we use on our site.
This is a work in progress – if there is a term we use that you don’t understand and would like to see added to this glossary, please let us know!
