Gym-type rubber for sub flooring?
Thinking of using a 3/8" thinck rolled rubber flooring as a sub floor to avoid rot and too much headroom loss with insulation plus ply... This is a tropical to temperate weather bus so dont need a lot of insulation. Was thinking that just enough rubber would even and protect the metal floor, give it a bit of insulation, and tiny bit of give (cushion) to the floor before using flooring or mats in the open spaces of the bus.
Anyone done this?
