Kitchen ceiling ready for trim coil

Here are pictures of the completed tubing on the ceiling of the kitchen. One picture is right before installing the 1/2" foam furring. The tubing is spaced more closely together along the exterior wall to give more heat there. The other picture shows the foam furring; this foam is the same thickness as the tubing, so we can apply drywall below the system.

Before we install the drywall, we will cover the entire kitchen with thin aluminum called trim coil. This aluminium will press tightly against the tubing, helping to distribute the heat away from the tubing into the room. It will also hold the tubing up. We will remove the existing clamps that are holding the tubing up right now. If left them, we would hear the tubing move every time it expanded (due to change in temperature). Also, the sharp copper straps holding it up would eventually cut a hole in the tubing.

Tomorrow we install the foam furring in the dining room. Here the foam serves as furring, a moisture retarder and a little more insulation.
