The groups "ProfiPlus", "Profi", "Natural" and "Basic" include new and well-tried underlays according to their characteristics.
By means of a sound box, which can be placed in the counter area, a walk or room noise of two different underlays will be simulated, as this type of noise reduction in particular is an important aspect for the customer. By the Acoustic Black 2.0 which is used in the box the surround sound may be improved by 27,5%, although this is just a thin polymer underlay = not the weight itself but the material makes all the difference!
