Several weeks earlier, Schrupp Excavating allowed access to the water and electrical lines. After water and time were given to allow for settling, we were prepared to begin construction.
If you look at the south field of the HUG campus, you might see a little pink. The foam insulation for the TWARC foundation has been installed. A layered method was utilized to help maximize heat retention. We went with five layers along the walls, with five layers on the floor.
Here you can see the amount of hose we would be using to heat the double occupation house.
Once the insulation was installed, we laid plastic hosing along the base. The hosing is meant to take the heat from the greenhouse (not installed, yet) and bring it to the foundation where it will keep the house warm. You can see where the hoses are sticking out. This is where the greenhouse is planned.
