The tubing is called "Wirsbo" and I believe it is some fancy brand name PEX tubing. Screw that. This is a yurt made from mostly recycled material. It doesn't have to be as cool as Robo-cop riding a unicorn.
Yesterday Christy helped me caulk and staple the Reflectix insulation to the bottom of the platform. She took endless amusement at my unfortunate position under the platform and giggled every time I said "ow" or grunted with discomfort.
There are many open spots where we cut away the insulation to accommodate the 4x4 supports. Today I will close them up with thermal tape and caulk and then I'll begin screwing down the first layer of floor which is 1 inch plywood that is saturated in concrete.
After that is down I will destroy a couple router bits while making the spiral shape in the plywood which will house the PEX tubing. After the PEX is in then another layer of 1" planks goes over the plywood. Overbuilt!
Hope Lumber & Supply, out in Longmont, sourced me some 560 feet of 8' x 1/4" X 1-3/8" lathe boards. It's going to be more expensive than cutting the lattice material out of 2x4s but it will be much quicker. I hope to have the platform ready by the time the lattice material arrives in a couple of days.
I have emailed one canvas tarp supply regarding one 50' x 6' fire retardant canvas tarp for the walls. I am looking at fire retardant temper tent vinyl covered tarp for the roof. It's black on one side and tan on the other side. I hope that I can flop it for the winter and summer months. The company should get back to me in a couple days.
