We've done quite a bit...we funded a lot of research for the National Research Council to actually have fire tests of these larger buildings. As Mr. Mason said, in the heavy timber buildings, with some of the new engineered wood products, for example, cross-laminated timber, what essentially that is, is it's a number of two-by-four dimensional lumber pieces glued together. They can form a panel. They could be anywhere from four inches to six inches or eight inches wide but they can go up to about 40 feet or 50 feet long. These are quite significant pieces of panels.
I like to use the analogy of a campfire. You have a lot of single small pieces, and that's how you start your fire. If you ever try to put a big log in, it just doesn't burn. It chars, as Mr. Mason said. We've done a lot of research and funded a lot of research with the National Research Council that will designate the fire safety ratings for these new engineered wood products.
There has been a lot of press about fires in buildings under construction. That is a big difference. These are construction fires. There is no gypsum sheathing around. I'm talking about the smaller buildings that are built out of two-by-fours. Under a construction scenario there are no safety measures yet to protect the wood, although in the new version of the national building code there will be some provisions that will have certain parameters that a company must follow when it is constructing on site. Once the building is completed, with all of the different products that go around the individual stick pieces of wood, fire ratings are tested and verified by the building code officials to withstand fire and to allow people to get out of the building. Every product in every application has a rating system that's per code and per the specifications of the national building code.
