That's the paper and the gypsum which is on the inside. So it's 95% recycled. The paint which is on the outside is 100% recycled paint, low VOC, water-based paint. So you can go to any building store and buy this similar paint right now without any problem. The wood inside the house is about eighty-five percent FSC-certified. All the lighting in-house is compact fluorescent except for what's in the kitchen which is halogen. So we want to demonstrate that opportunity around that. So there are lots and things which you can't see which are in the walls and on the walls, which are very, very sustainable. The other thing that is behind that drywall is the structure of the building. This building uses advanced framing and what that means is that it's typical stick framing housing, but instead of being every every 16 inches on centre, the wood is on every 24 inches on centre. And by doing that we reduce the amount of wood to build this house by about 20%. This house here has 24 inches on center, 2 x 6 walls, which is typical in today's construction. We filled that 6 inches with 6 inches of Roxul insulation. And Roxul is a really unique insulation product because it's made from recycled slag. Slag is a recycle material from iron ore, and they basically spin it into a insulated bat which has one of the highest R values around. It's about R 24 for the 6 inches. Code requires that a house have R 20. Most houses have all these studs that go from the inside to the outside, so their called thermal bridges. They actually have less of an R value than the insulation which is directly behind them. By putting that insulation all around the outside, basically what you do, you basically stop that thermal bridge from happening and it makes a house a much more insulated envelop.
