Did I mess up?

Hey guys!

So I just laid down my floating subfloor with 2x4s and EPS foam board from Home Depot. Overall the floor is solid but I have a few squeaky spots that are driving me nuts.

Upon further research, I see that most people are using XPS for more rigidity among other reasons. Assuming I fix the floor creaks, is my 1.5” EPS foam alright? Did I make a mistake?

Side note: The bus is a 24ft 7.3 blue bird. I plan on taking it for ski trips in the winter, and live in it full time. I don’t want to rip up my floor and replace my insulation, but I want to do it right.

I live in a house built about 100 years ago, and has been moved about three miles from where it was built in 1960. I have so many floor squeaks I can not count them all. Nor are my floors flat and level.

My bus is kinda the same way. I dont really care about a squeak here and there. I used the pink foam 2" and 3/4" plywood on top of that. I do not have any wood framing structure - steel floor - 2" foam- 3/4" plywood. The stuff like seats, cabinets, refrigerators, toilets, beds, that bolt to the floor and walls are what hold most of the ply/foam floor in place. There are assorted bolts that go all the way through to hold an edge or corner down here or there.


Nope I cant stand all the way up in some places. That's okay If I sit down all is good. I think that 2" and 3/4" of wood is a hell of a lot better than kinda rotten plywood floor over steel.

If I could convince ---- I would tell you "It doesn't have to be perfect, just good enough."

XPS is going to squeak just as much as EPS. The main advantage of XPS over EPS is R-value (XPS is rated R-5 per inch while EPS is rated R-4 per inch), but: XPS has a higher R-value because the blower gases used in its manufacture have a lower thermal conductivity than regular air (which is what forms the tiny bubbles in EPS). Over the course of a few years, the gases in XPS will migrate out of the material and be replaced with ordinary air, so eventually XPS will have the same R-value as EPS.

General concensus seems to be you did OK.

Thank you for all the responses! I feel much better now!
