Hi All,
I completed my subfloor months ago, and am unfortunately considering ripping it out and replacing. Looking for advice on addressing some issues I have with my first iteration.
My subfloor is 1x2 pine slats, both horizontal and vertical, creating a lattice structure at an elevation 3/4” above the highest ribs. These pieces are adhered to the van floor with marine adhesive. Then, the voids were filled with standard Thinsulate SML 600 (non-compressible), and the stud/lattice structure was skinned with 1/2” BB primed ply.
Overall, the floor is extremely level and solid. There are no low spots, and I can bolt through the body pretty much where I choose without the floor deflecting much (close ribs, pretty rigid BB ply tied down with *many screws into the studs.
But-every time I walk on it, it makes slight creaks/noise. It sounds like an old hardwood floor in a house. I’m noise sensitive and it annoys me a ton. I think the adhesive perhaps is not a great solution when the body flexes, resulting in glue failure. Then there is independent movement between the studs and metal floor, and the movement creates noise.
I am debating mini cell or the other kind of Thinsulate (au400 I believe); filling the low ribs with minicell, then a single layer, then 3/4” or 1/2” BB ply and bolting it down. For those of who have done this: is it *solid? Does the floor feel rigid like a slab, or is there give? Do I have to block areas where I will bolt cabinetry/batteries etc, and the doorways so the minicell doesn’t compress? I want a solid floor like I have now, but without the moving pieces/noise.
I know this topic has been discussed at length, but I’m wondering about specifically noise/compression properties.
