|School Bus Insulation||Bill Tietz||6-25-06|
|Do the ceilings of the bus need to be insulated and what would be the best type to use if needed.|
I was worried about condensation when sleeping or cooking!!!

|I've spent the last three years living in a bus up here in alaska the first winter i froze then wisened up to expanding foam. I had the floor foamed from underneath so i would not loose headroom. There is about 6 inches of foam giving me a r value of 30 and i have also covered the floor on the inside with exercise mats so they are sorta warm to the touch. My ceiling and wall coveringhas been removed as well as the old insulation and the ribs were drilled and filled with foam and i sprayed enough foam to fill the voids between the ribs and skimmed over the ribs so there was no metal contact into the room. The first winter the ice would form on these first so it is important to cover the metal. I did the same with the walls as well. Next I covered all the walls and ceiling with insulated bubble wrap. I made sure to seal all seems real good so no air could move behind the wrap. I live in a space ship but, all this work was necessary to achieve the most r value i could get in the smallest space availabe, and was learned through trial and error. I have been through streches of cold well below zero for weeks and still find it comfortable. Spray foam is the way to go!|

|The roof is made of an inner and outer layer of steel with insulation already installed.|
I'd say if your bus is 1988 or newer, then you won't need to add any insulation; if it's an older buss, you'll probably need to inspect what's there and make a decision.
I've seen a lot of things done with expanding poly foam insulation, and that's what I'd recommend. As for condensation, more air flow = less moisture to condense. Keep the interior well ventilated or well air conditioned and you shouldn't have any problems.
Hope that helps!

|Yes, the ceilings are already [lightly] insulated with fiberglass insulation.|
The floors are not insulated. I have just insulated my firewall with the reflective bubblewrap stuff from Lowes (like what they make car windshield parking screens from). And I have just covered the firewall and floor entirely with top grade carpet padding.
Next I am laying down outdoor carpet on the floor. I am contemplating what to do with the walls and windows. I plan to install a windowunit home airconditioning unit and port the heated cooling exhaust via insulated flexible ducts from a homemade cabinet.
All the best!

|Having an "81" GMC, Thomas built, propane conversion, I soon found the head room is a problem(I'm 6 ft ). I opted for the spray insulation on the underside and inbetween the 1/2 round moulding on the exterior. As well as copious poly stuffed glued and caulked everywhere else you could think of. For the past 3 winters I've had ample time to narrow down numerous drafts. the front compartment (the steel frame wall runs directly behind the drivers seat)is fitted with interlocking panels made from regular tarp material into long flat bags stuffed with, you got it, bits and pieces of all the poly I've saved over the years. Closed cell foam sleeping pads are excelent for window covers, you just have to hope and pray to find them in number at a low price.|
More tricks developed daily :-)

|I have a 95 Chevy short bus and need some tips on insulation. do i need to frame the walls and top? or just put up the insulation and than my wood walls?and what kind will be best i live in the rocky mt.|

|I am converting a half bus, and love the open feeling with all the windows, but in the winter even in California it's going to be cold. I am curious how you would use the closed cell foam pads as window coverings.|
