Hello, We have been looking into getting a SpaceSaver moveable storage system put in at our museum. In the plan, the company is proposing using 3/4" plywood for the subfloor. This will provide the space in which to place the rails for the system. As plywood is renowned for off-gassing I'm wondering if anyone has found/used an alternative material for the subfloor over a concrete pad floor. Thanks, in advance, for any suggestions.
