POLOPLAST has worked on the issue of noise protection in above-ground drainage systems for over 20 years. This competence is reflected in the noise-insulated above-ground drainage pipe systems POLO-KAL NG and POLO-KAL 3S.

With its three-layer design, POLO-KAL NG, the noise-insulated quality above-ground drainage programme has been an established name in the sanitary branch for the past 15 years. Over the course of many years of collaboration with universities and testing institutes as well as specialist planners and installing engineers, continuous development efforts have lead to a product system, which ensures long-lasting living comfort, a sense of wellbeing and a high quality of living due to its innovative 3-layer technology.

POLO-KAL 3S, the three-layer highly noise-insulated above-ground drainage pipe system has been in the market successfully for 20 years. The intermediate layer of the pipe is made of the visco-elastic material POROLEN. This material dampens knocks and vibrations and absorbs air- and structure-borne sound waves, thereby reducing drainage noises very effectively. Designed as highly noise-insulated discharge pipe system, POLO-KAL 3S is the ideal noise-insulated pipe for buildings with stringent requirements upon noise insulation. POLO-KAL 3S has proven to be an outstanding noise protection solution, particularly when used in the down pipe.

POLOPLAST pipe systems meet the high demands placed upon noise protection
The measurement results of the sound tests carried out at the Fraunhofer Institute for Building Physics in Stuttgart in accordance with the European standard EN 14366 provide impressive proof of the superior noise protection competence of the POLOPLAST 3-layer pipe systems.

Even at a volume flow of 4.0 l/s in the down pipe, both above-ground drainage programmes achieve results significantly below the noise protection requirements of ÖNORM B8115-2 and DIN 4109.

The above standards set the minimum requirements for MEP installations at 30 dB(A). The normative increased noise protection of 25 dB(A) is recognised as current state-of-the-art. At 25 dB(A), the increased normative noise protection „only“ differs from the minimum requirements set at 30 dB(A) by 5 dB(A). However, the fact remains that an increase of 3-5 dB(A) is perceived as twice as loud. An increase in the sound pressure level, e.g. from 17 dB(A) to 27 dB(A) means that the drainage noises sound approximately three times as loud.
