I can start quickly. I'll go back to the comments that Phil made earlier about the tests we are carrying out, just to give you a bit of the detail perhaps. For example, we have here in Ottawa facilities where we are basically duplicating apartments and rooms. We're building the four walls with openings, typical openings.
We have a series of architectural designs, some with timber exposed and some without, and we're basically putting thermocouple sensors all over the place, monitoring the temperature rise and temperature evolution in different conditions with different amounts of timber exposed, to get all the data to be able to feed that back to the technical committees who will look at this and then make recommendations to the commission. We're providing the data. Of course, gypsum will have an impact, but we are there just to provide the knowledge, the scientific basis for decisions.
