I'll ask Bob to answer the question, because he has been working with this for years. The key thing to keep in mind here is we're not talking about stick building. We're not talking about two-by-fours. Yes, two-by-fours burn in a hurry. We are talking about mass timber. In this case it's typically engineered wood, but mass timber doesn't burn. Mass timber will char and then protect itself. That's the secret to using wood in large buildings.
Bob, could you speak a little bit to some of the work we're doing?
