Sound-insulating composite panels

Noise is a problem of our modern time. Our environment becomes increasingly noisier. Therefore, it is an important task, to reduce noise pollution effectively to a minimum. We took up this challenge and developed a series of sandwich elements that have special noise control characteristics in addition to outstanding heat insulation. These elements can be used, for instance, in window sills, doors, shutter housings, machines, or equipment housings or as sound-absorbing hoods.

We are offering sandwich elements of several sound transmission classes (I to V), from which a huge number has been tested by the ift (Institut für Fenstertechnik) referring their noise insulation characteristics.
