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.
COSMO® Silent (dB 38) - ALU
ALU on both sides, XPS core, ALU insert
Composite panels with special sound insulation (dB38), consisting of a pure aluminium cover sheet AlMg1 with a thickness of 1,0mm and a core of extruded polystyrene foam (XPS).
COSMO® Silent (dB 46/50) - ALU
ALU on both sides, core of mineral wool, heavy-film insert
Composite panels with special sound insulation (dB46 - dB50), consisting of a pure aluminium cover sheet with a thickness of 1,5 - 2,0mm and a core of mineral fibre insulation (MIN).
