 Their work right now is where people are going into houses, they're remodeling them and taking out like an entire wall. The wall that used to have the sliding glass door on it that went out to the back patio or to the deck or the covered area, they're taking out that sliding glass door and they're opening it up and making it two or three times wider. They're making a whole wall of windows that when you open it up, you can stack them all the way over and the outside becomes the inside.
