Are you building an apartment block, a hotel or other similar structure which needs walls that will provide enhanced sound insulation?

VELOX have designed products specifically for these cases where increased insulation is achieved by increasing the concrete core.

  • Walls for special use
    The supporting wall of terraced houses or flats TT 19 double - the rate of silencing Rw = 77 db.
    Load bearing partition walls without reinforcement to the quality of the concrete C 12/15 to C 25/30, with plaster on both sides with a thickness of 15 mm.
