Typically, vapor barriers are placed toward the inside of a living structure. This is to stop any moisture from the interior. Since you will have a clad aluminum exterior to your floor and foam between floor joists, a vapor barrier isn't needed.
My 46 yr old trailer has an exterior clad floor system with wood joists and plywood subfloor. While insulating and inspecting the floor system (pulled off subfloor), I found that all of the frame and the subfloor were in excellent condition.
thank you thank you <3
I am "recladding" it myself with pvc coated aluminum and alumirbond to seal the seams(between pieces) on the outside, which are overlapping. between the aluminum and the steel frame I'm sandwiching butyl tape where the staples and bolts go through the subfloor and the steel frame. along the (final)seams, ill be using proflex geocel for RVs. between there alumirbond, butyl tape, and the proper trim(which I still need to source and purchase)
is it enough? I don't know how good alumirbond is, but I do know how to use it properly and when done right, its supposed to be "strong as steel" so it should be a strong seam holder. thank you!
