T 1-11 subfloor?

[Enrico Carini]

Looking around at all the threads about sub flooring, anyone ever try T1-11 instead of plywood? Does it off gas harmful chemicals? Seems like it would work better than plywood with that awesome coating on it.

Not into the foam board idea

Why are you not into foam board? It is designed for the job.

Mostly because I'm 6'4" in a 6'2" bus so I'd like to keep the floor as thin as possible

A reasonable point.

It's going to depend on how you plan on using the bus. SHort camping trips in moderate weather, just bung down 1/2" ply and a laminate on top.

However, if you plan any camping in cooler temperatures you will regret the decision to not insulate the floor, or the ceiling.

If those ideas are in your plans, take the time and raise the roof a few inches. It's not beyond the capabilities of any half-decent handyman.

I'd love to do all of that, maybe on the next bus or a later chapter but I kinda need to knock this one out.

I was just kinda thinking T1-11 might be nicer than regular ply.

No one leaves a regular ply finish on the floor.

Get the cheap stuff, put a thin laminate on top.

For sure, not even I would cheap out that hard. I’m thinking for sub flooring T1-11 has awesome resistance to moisture since it’s siding and all. Proper flooring will go on top of whatever I use as sub floor

If the floor is sealed it is an awesome vapor barrier. The occasional spill won't do it any harm. My floor is 18 years old and has had kids in and out. But there is no rust and no holes. The OEM plywood is in perfect condition.

I was surprised when talking to the woman in the flooring department about wood flooring for my bus. She immediately blurted out that that would void the warranty, that none of the wood flooring was intended for temp changes that we experience in a bus, that it was only warranteed for like 50-90°

Just avoid the stuff made from MDF or particle-board, leave a gap and it will be fine.

I was seeking advice on boards or laminates that were not particle board and she said none were. then she started showing me the water proof laminates that started at $2/sf, more than I want to pay. Leave a gap where?

Leave a gap around the edges.

Leave a gap around the edges.

Of each board or around the perimeter? I plan on using a snap together design. It would be a floating floor until I install cabinets and secure them through the laminate and subfloor. I plan on leaving a perimeter gap for contraction and expansion.

 

[Jolly Roger bus 223]

I have done the snap together stuff in my entire house and didn't quite follow all the directions for expansion and contraction which is cut the boards a1/4" short at the wall and when you do trim to use a minimum of 1/8" from the top of board to the bottom of trim and I can tell you that as my house temps change so does the flooring where I was a little to tight.
Winter it's fine it's in my fall,spring, summer months where we leave our windows open that we see the bowing/buckling.
For in my bus I ended up salvaging some engineered bamboo and teak 1/2" thick glue together.
I used a 1/4" foam underlay and screwed 3/16"-1/4" birch ply on that throughout.
Built all walls framing and everything on it. Used solid sheet rubber flooring for all the wet area's including turned up edges to contain the wet spot
And only did the finished floor in the visual finished floor area and some salvaged 1/4 round oak trim (for me) to complement the bamboo and teak. Most of my dash is salvaged Brazilian cherry stair tread and teak flooring. If you don't mind mixing it up a little.
Don't go to the big flooring companies around because the want to sell there scraps for the same as a new floor.
Go to the smaller company that has **** under his feet and will give it to you so he isn't got to pay someone to get rid of it.
My actual floor is.
1/4" foam board
1/4" birch ply/luan
1/4" recycled carpet/foam mess that is going to compress over time
And a 1/2" finished floor board.
That's a 1-1/4" floor raise with insulation in it.
If I ever win the lotto?
Then my spray foam after many of hours of work will be applied from underside.
But that requires all storage binsframing tank frames and all wiring you ever need/want to see again either moved or secured so you won't ever have to see it again.
I have it in my head but I will never win the lotto so it's back to work to pay the bills and extra curricular activities? (teenager ready to drive,teenager driving and ready for college, my old 77 truck that needs a tranny. WIFE) BUS

Simply wondering if anyone thought using T1-11 as subfloor was a good idea

Usually when that happens and you haven't gotten the answer you want from such an informative forum common sense would say it's probably not a great idea or someone may have used it. T1-11 is siding with grooves in it, not intended as flooring. Doesn't sound like something I would consider.

It's a good thought because of the weather resistance qualities. I'm assuming you're talking about using the T-111 for subflooring. It seems similar to using marine grade plywood.

On the other hand people don't get flooring containing wood fibre because of its tendency to have issues.

That makes no sense

thanks. I might use it as sub flooring though... because of the aforementioned properties

I don't know if this will work for you but it's what I have done when headspace is limited. I use 1/2 foam board, preferably isopoly with 7/16 OSB. Then I tape the seems and glue down a vinyl roll flooring. Never use the self-adhesive squares or strips. Any heat above about 85*F and they will peel up and start sliding around. I made that mistake once because I was trying to go cheap.
