VST Wall

VST-walls are made of two 24mm thick cement-bound particle boards, which are connected to each other by our own specially developed steel spacers. The spacers are connected to the cement-bonded particle boards from the inside with galvanised countersunk screws, without penetrating the surface of the elements. This preserves the ready-to-paint surface of the VST-walls.

On the construction site, concrete is poured between the cement-bonded particle boards. The  concrete bonds with the cement-bonded particle boards which are thus not removed but become part of the building as stay-in-place formwork.

The following wall types can be manufactured:

Overall wall thickness =175mm (concrete core = 127mm)

Overall wall thickness = 200mm (concrete core = 152mm)

Overall wall thickness =215mm (concrete core = 167mm)

Overall wall thickness =230mm (concrete core = 182mm)

Overall wall thickness = 250mm (concrete core = 202mm)

Overall wall thickness =300mm (concrete core = 252mm)

The overall thickness of a wall element (architect’s measurements) is the thickness of the concrete core plus 24mm for the cement-bound particle boards on each side.

Cut-outs and openings are made in the factory. The installation of empty electrical piping as well as sanitary and heating piping is also possible in the factory. The maximum weight of a VST-wall is approx. 70kg per square metre without reinforcement and without installation parts.

The inner wall formwork serves as edge support for the slab, so that no additional edge support is required.

VST walls have fire protection class A2-s1, d0.

Due to the solid construction method in which a jointless structure is produced in the final state, good sound insulation values are achieved for all wall widths offered by VST.
