How are the electric and plumbing lines installed in the wall of the dome shell?

Almost all of the electrical and plumbing will be contained in the interior frame walls, in the same manner as conventional housing. To install electrical wiring in the exterior dome walls: simply cut a groove in the E.P.S. insulation and wall board and insert the wire. Fill the groove with spray foam and finish the area with joint compound and tape. To install electrical boxes, conduit, or plumbing pipes: cut the E.P.S. insulation and wall board slightly larger than needed, insert the box or pipe and fill in the opening with spray expanding foam. The spray foam will harden in about half an hour, holding the box or pipe secure. To learn more click on Electrical and Plumbing.  more
