[Technical difficulty—Editor] ...which principle it is, but there are many different processes in development right now in the world. We're heading into an area that is really important, which is the durability of the product and the protection in the product. To also have strength is another element. We need to do more research on those elements and we need to try to go faster to develop those kinds of products and to make sure that products that I use outside are competitive with other plastics that exist or other materials.
We know the technology is there. It's just a matter of applying it properly and to make products that need really minimum maintenance. As you say, the stain on the wood siding that Maibec does allows us to now be able to give you 50-year guaranteed maintenance-free material. That wood siding from the 1960s was about 80% of all the siding that was on houses in North America, and now wood is used for just 4% or 5%, due to the maintenance. Knowing how to achieve durability of the product and use the stains and all of that allows us to bring that material back to the forefront on a competitive basis, since we're able to have it closer to maintenance-free.
The densified wood has pretty much the same orientation for the future in building structures that are really stable, and it probably will allow us to build higher and stronger with wood.
