With electrical, plumbing and framing inspections passed, it's time for the foam insulation to start. The crew is going to be using an open cell foam by Johns Manville. It will be a complete foam envelope. An
amazing feature of the foam is that in 24 hours of full sun exposure, the radiant heat will only penetrate 2/3rds or so of the foam insulation. Drywall will be following the foam rather quickly. The drywall crew already has all the drywall laid out, ready to go.
So far, some of the green features of the house are proving to be a bit of a challenge with the plumbing of the radiant floor heating. The factory engineers are being a help and the plumbers have attached the zone pipes to the headers. With factory support from Uponor things seem to be moving right along.
Hopefully, the pace will pick up. Cabinets, lighting, ceiling fans, floors and the appliances are all picked out and ordered. It will be fun to watch the trades complete the house.




The home is generating a lot of interest in it's green features. Just a few of the green features is complete foam envelope, solar radiant flooring, double pane-low e windows, lot orientation, and renewable bamboo flooring. There's going to be a lot of activity from here on in. Now if we can avoid delays....
This took about a day, then the lot was leveled.
The foundation forms are up and fill dirt has been brought in.
It looks like we have the final plans for the radiant floor heating.
The steel for the foundation is in and the tubing for the radiant flooring is going in.
It started slowly, and picked up steam. Can't tell you how many people think it's a little weird to put a solar radiant floor in central Texas, but I have a feeling that when the winter heating bills come in, there will be some grins when the negligible utility bills hit. If things are on schedule, the cement comes in next week and we'll have a real live slab. Then the real fun begins.
