All I know is what we did. I'm mostly here to try and learn more about y'alls method through osmosis.

It's been mentioned that heat rises.

HEAT DOES NOT RISE.

Hot AIR rises.

It's also been mentioned that speed kills,

I contend it's the uncontrolled stop that does it.

Just like falling doesn't kill...just that sudden stop at the end.

Heat rises, so essentially we feel that the floor does not lose much heat, and rugs and socks can help with cold feet. The height lost will be put into insulating a ceiling, for we don't want to lose height both directions. We are also super insulating the walls, and running rigid foam UNDERNEATH the bus, instead of the floor. He suggested just gluing The floor onto the metal, but we want a vapor barrier....has anybody done something like this? We don't feel we have the time or resources to do furring strips, nor do we want to lose 3 inches of floor and not have room to insulate the ceiling...
Ugh ... this is so wrong. Can't we go and reference the other eighty posts that address this exact topic? Yes, heat rises, but that floor is a great thermal bridge to the outside. You will be pretty cold (or hot) depending on where you live.

Generally, heat loss in a home:

Roof/attic – 25%
Windows and doors – 25%
Walls – 35%
Floor – 15%

But a bus is a tin can ...

I don't understand how people can do all their due diligence in researching a topic only to come to the wrong conclusion. Those figures on a home take into account you are using home materials and home insulation. Fiberglass insulation with air gaps. 2x4's. insulation on the outside AND inside. Check THESE recommendations out ... You will be lucky to have an insulation value of R1 or R2 with your plan.

The floating floor is half assed. That foam is really not supposed to hold all the weight people are putting on it. Check the ratings and you'll see. Ever stood on top of a foam cooler? Why not? Right, because it's foam. And it's not meant to support your weight. Some have done the floating floor right and used supports ... most haven't. To each his own. Take the best from both concepts and just frame like you normally would, but glue it down instead of screwing it in to prevent thermal bridging. Then put in your insulation, tongue and groove plywood over that, and floor over that. You'll lose maybe 2 inches if you skimp, 3-4 if you go overboard. It'll feel much warmer. You are looking at a potential R value over 10 if you use the right materials.

Id never put spray foam under my chassis. It's too clean and beautiful to mess it up. Then it's going to get wet and eat away at my perfect frame. Some have done it with success. I tinker around with too much underneath to ever dream of coating it in that gunk.

FWIW-My house has a big Florida room that's basically a slab with tiles. In the "winter" here, the room is VASTLY colder than the rest of the house, which has floors that are better insulated.

All of the good build threads here provided all the info I needed when deciding how to build my floor.

I used 2x4s on edge to create a framework, then filled the gaps in the frame with 3.5" of rigid insulation(only 3.5" because an actual 2x4 measures something like 1.75x3.6. Laid 23/32" tongue and groove osb on top and then my 12mm laminate flooring with backing pad ontop of that... Solid as a rock and well insulated for both summer and winter.

Don't skimp on insulation if you plan on spending alot of time in your bus.

And I'd bet you have zero issues with your tongue and groove laminate flooring coming up or warping.

therers a reason why your feet used to freeze in the old Jeeps before they started actually insulating the floors better...

im not sure the R-value but I can say if you are crazy worried about ceiling height that even dynamat helps some with heat loss... likely over-kill for a whole bus floor due to the cost and weight.. but it does help..
