subfloor

Some planks have interlocking edges, while others, including yours, are designed to be glued directly to a subfloor.

If you have a “floating floor” with manufactured wood flooring glued or clipped edge-to-edge and not to the subfloor, you might even be able to make the switch yourself, provided you have extra pieces.

Carefully remove all finished flooring in balcony and porch chamber, taking care not to damage subfloor.
