Moving right along in the addtion the TOS is well underway. We wanted to get all exterior walls and ceiling insulated before the heat was turned on. This was done by drywalling the ceiling first and getting insulation down on top of it. Then the walls were wired and insulation was put up. In addition to insulation plywood was put up on the walls and they were then drywalled. This will help on energy costs to the undergrads as well as keep the new air handler from staying on for long periods of time.
