Thanks guys, I guess that leads me to my next question or questions, I have found someone to do install the spray foam at $1.50/sq ft, is that a fair price? I have the interior gutted and don't want to drill holes in the framing, so wouldn't I go ahead a spray the foam in and then build my wiring etc. into the lining of the bus? I was thinking of strapping the inside alowwing me to run my wires etc. then line it with plywood or something. Am I on the right track? I'm not sure how to go about the wiring and plumbing before I insulate. | ||

some have installed conduit in some key locations so you can pull in wire later. IE ceiling for AC, one or two down each side. | ||

If they are going to spray for 1 1/2", that is reasonable. I roughly figured a max of 800 sq. ft. with no windows - just walls and ceiling. $1200. I would not worry about wiring except to get wires to your exhaust ceiling vent fans, and roof A/Cs if you have them on the roof. Wiring can run in the bays, chases along the floor or chases in valences. Ed Roelle Flint, MI | ||

Grant - Also suggest you install furring strips horizontally along the walls and matching on the ceiling before you spray foam. This will give you slightly more insulation, plus provide a base to hang the plywood. Put blue painter's tape over the furring strips before foaming, too. If you've got a company in town that repairs 18-wheeler reefer trailers, talk to the shop foreman and see who does their spray foaming. You might be able to have him also do your coach at the same time he's doing some trailers, which could save you some $$. FWIW & HTH. . .  | ||

Thanks guys , some excellent ideas. I have run the wiring for the a/c etc, so I guess I'll go ahead with the foam. | ||

My Dad spray foamed my bus before he sold it to me. Be sure to plan ahead for low-voltage lighting, tv's, outlets etc. Everything that runs thru the roof bows make sure to use the right pass thru grommets so you wont have a short later. Then took it to a guy and had it foamed. To finish it up he used a textured kind of shiny shower board which makes nice curves, is cheap and readily available, and has moulding to connect edges of panels. All this was done front to rear before any interior walls were built. Bone color looks bright and clean, and can be washed as much as needed without fear of ruining the surface. (nice for kitchen areas) Also, he said the foam/shower board combo really quieted down the interior while driving. |
