Last summer, I noticed the back of the bus got very warm while otr. So, I took the bedroom apart and found - no insulation whatsoever over the engine or the radiator area. My question, what should I use to insulate this area? I was thinking about using the 2" blue foam sheet insulation that is used on the exterior of homes, but I'd appreciate the advice of the experts here. Thanks | ||

jim I would be very careful about using styrofoam insulation as it will give off a toxic fume if a fire were to occur. I have heard it squeeks as well with movement. I used a sound deadening insulation called Roxul. It is made from lava rock and the mice can't live in it. It is quite dense so won't move with motion if packed in fairly well. Don't pack too tight or you will defeat the purpose of insulation. I am no expert but this is what I did over 25 years ago and it works. Bill | ||

Hi Bill, Thanks for that advice. Is Roxul the same as rock wool? It sounds very similar. Would a reflective foil backing also help to reflect IR heat back into the engine compartment? | ||

Jim I have heard of rock wool but not sure if it is the same thing. Roxul is a brand name so maybe a web search would give you more info. We can buy it at Home Depot. Reflective foil has very little insulating value but does reflect heat. It is hard to keep the engine heat out as in time everything gets so hot from driving but anything you do helps to a certain degree. Bill | ||

you could start with 1or2" inch duct board (they use this to make heat and A/C ducts in forced air heating in homes nowadays) before adding jute carpet padding, which will also cut down noise. Eventually, it will all get warm after 6 hours at highway speed. | ||

Work the other side of this too. Get the heat out of the engine room. Every degree that you get out via custom venting can't soak up into the bedroom. Vented skins for the engine doors are available, IBP is one place. happy coaching! buswarrior | ||

Jim.. I painted all the metal parts with a ceramic paint made for reducing heat. Used it on the whole inside of my bus before insulating. Then I used spray foam the floors, walls and ceiling. I dont get any temperature change with engine running. | ||

Hey Jim and Wendy. I put down heavy black tar paper with plenty of overlaps then sheet lead from a roofing supply ( also got some from a plumbing supply house that had been damaged. We bent it over the ledge on the back "bench" and down to the floor. Over this i used a foil bubble wrap that came in a large 4' roll from HVAC supply. Used alum tape for the seams. For the back bulkhead i also added foam board but for the floor i put 3/4 ply (i had to redo my floors and neede the strenght and thickness) then carpet padding and carpet. Its quiet and no more heat even after running all day. The lead handles the noise. i went hru the archives and did lots of searching. Lots of ways to do it for sure. Just gotta crank your favorite sat. station and go to work. | ||

If I had the money I would probably do it like David or Cory. For me I am hoping that 2 layers of the foil bubble stuff does the trick for reducing heat.... maybe that ceramic coating paint stuff too. | ||

We did the bedroom (above engine) as Cory did, using 'Temp Coat'. Wish we had done the whole bus. http://lawrj.sasktelwebsite.net/interior.htm | ||

When we stop for the night , we simply open the rear engine hatch on the Sportscar. It cools off in a couple of hours with no effort , expense or fire danger. FF | ||

Hi, A search reveals that "Inusl-All Temp-Coat" is a more user friendly product that can be applied via brush or roller. This is what I need since it is to be applied inside a finished bus interior. However, a search of the internet did not reveal a source. Where can I buy this stuff? Thanks, JIm | ||

Sorry, I can't remember where we ordered Temp-Coat from. We live in Canada and I do remember it was imported from the US. Also I remember, they used it in school buses in the hotter states. School Bus company may be a starting point. It is Great Stuff, and easy to apply with brush or roller. Good luck | ||

Why.. would anyone want "Insulated Paint"? Paint does not care if it is hot or cold, Perhaps you meant to refer to INSULATING PAINT something that prevents heat and cold from reaching the surface being PAINTED.... saying what you mean and meaning what you say clarifies your intentions.... words do have meanings! FWIW ...when one searches on Google, the term "Insulated Paint" it ASKS the reader if they mean "Insulating Paint" .. at least on the Google used on the 3rd Stone from the BIG Heat.

"who would want insulated paint? NASA google and read the articles." STOP IT... you're killing me..!  Here's where I do you a favor AGAIN ! 1- The TOPIC is INSULATION PAINT (paint that insulates) 2- INSULATED PAINT would be a liquid that is INSULATED (think paint with insulation attached) 3- I took your original advice & GOOGLED "Insulated Paint" and do you know what GOOGLE said? it asked if I wanted "insulation paint" 4- taking your most current advice I went to NASA search & typed in the word GOOGLE & nothing showed up about PAINT or INSULATION... Thus I am standing by faithfully for your next set of concise instructions.... ya know, if Les had just one more BB in his Boxcar, I'd think someone was pulling my leg  (Message edited by Jack_fids on March 15, 2011) | ||

Just remember insulation works in both directions. IF you insulate the rear of the coach , 4 or more hours of heat will indeed heat the metal on the other side of the insulation. Then it will take 3x or longer to have the heat LEAVE , the sleeping area. Is this what you are looking to do? FF | ||

FF, are you saying if the inside of the coach is insulated over the engine that the engine gets hotter? It would make sense..... Maybe that's one place additional cooling for the engine comes into play or a mister system or something.. | ||

NO the engine wont get hotter , BUT all the "protected metal" in the rear will HOLD the heat far longer than if it were uninsulated. This should hold the rear of the bus hotter longer , not what is desired . FF |
