On our Mercedes Sprinter, the floor of the loading area is corrugated. Accordingly, we already have a profile that we can use to accommodate the insulation. At the same time, however, installing the insulation makes the surface almost impassable, because the insulation material does not tolerate pressure loads and thus would break down if we step on it. Accordingly, the very next step is to lay the OSB board on our supporting structure. It is waterproof – so it can also cope with any moisture on the interior floor to a certain extent and reliably distributes the pressure of the furniture and the people in the interior via the supporting structure to the vehicle floor. We have chosen panels with grooves and chamfers so that the panel transitions are also sufficiently stable and can absorb forces.

A good tip is to mark the supporting structure for the next steps, because for the furniture anchors, we need to know where to screw into the glued wooden slats. Later on, on the vinyl click floor we marked the supporting structure with tape so that we can remove the markings afterwards.

The top layer of vinyl click flooring is now laid on top of the load-bearing OSB boards. We lay the panels floating, only at the edge they are bordered. With the furniture, which we later screw on through the click floor, it is additionally fixed.

So that the floor construction is additionally protected and robust against the outside at the driver’s cab, the side door and the rear doors, we take aluminum profiles which we saw to fit and screw over the edge.

With the finished floor, we can now quickly move on to the interior. Next up is the partition wall to the driver’s cabin, a shelf above the driver’s cabin and the preparations for the electrical installations and the final wall cladding.
