In overall terms, yes, we've seen a steady progression over decades to move to more engineered products, such as the replacement of floor joists with wood I-joists and various other engineered components. We are, of course, creatures of building codes, so to see the widespread adoption of new technology, we need to see it proven out. We need to see it being accommodated and handled by a code and code officials.
We recently saw that happen with six-storey wood frame construction, which moved from a curiosity into something that is fully embraced by our industry. I know that there is a huge interest in cross-laminated construction in particular. At every conference of our association that I go to, somebody is showing us amazing pictures of these buildings.
This is really important in the cycle from when an innovation is developed till when it is in full commercial application. From our point of view, that's a process of de-risking something, and often it takes partnerships. It takes government encouraging and facilitating that transfer. There's huge interest. We're going to be building very differently in 10 or 15 years from the way we are building today.
The open question is the mix of materials and the type of materials, but more engineered and highly processed wood products have traditionally been a solution, and we would expect they're probably going to be one in the future.
