Decibel – soil and waste water pipes and fittings

Excellent sound insulation

Soil pipes with less water noise and lightweight handling

Uponor Decibel is a complete soil and waste pipe system with pipes and parts available in dimensions from 50 to 160 mm. Its suitable for  new buildings, as well as renovations. Mineral-reinforced polypropylene, a multi-layered structure and a high specific gravity help keep the Decibel system quiet. Decibel is well suited to acoustically demanding buildings. Certain noises are airborne, i. e. they are generated in the pipe and are carried to the outside air. Uponor Decibel’s multilayer construction with a mineral intermediate layer dampens vibrations. Other noises are structure-borne, i. e. carried from the pipe into the structure of the building via its fastenings, creating a resonant vibration. One way of avoiding that is to use noise-suppressing fastenings. Uponor Decibel is the most advanced noise-suppressing indoor soil and waste pipe, created after extensive research and development. It has resulted in excellent performance for acoustic damping, function, installation and environmental protection.
