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.
