Floating floors are not attached to the subfloor and must be free to move as environmental conditions change. To ensure this movement is unrestricted, an expansion gap must be maintained at every vertical obstruction, including walls, columns, and pipes. The gap width is typically determined by the material and room size, as specified by the manufacturer. If the gap is bridged—for example, by tight molding or cabinetry—the floor may buckle or peak due to trapped expansion forces. Transition strips or baseboards are used to cover these gaps while allowing the necessary space.

How are expansion gaps maintained in commercial floating floors?
Expansion gaps in commercial floating floors are maintained by leaving consistent spacing around the perimeter of the room, typically hidden by baseboards or wall base trim. This allows the floor to expand and contract with temperature and humidity fluctuations.
