Since 1990 the first sound-absorbing system that adopted the “mass / spring / mass” principle applying it to a polypropylene (PP) drainage pipe in white RAL 7035. A range with diameters from 75 to 160 mm. composed of 3-layer coextruded pipes with an intermediate layer in “Porolen” (a particular and patented rubber-like material) and fittings reinforced with mineral fillers (MV) which give the system the highest acoustic insulation performance, impact resistance, corrosion, abrasion and aggression of dissolved chemical substances in civil and industrial waste.
Waste drainage system compliant with EN 1451-1 in Class B (inside the building) suitable for systems in buildings where high acoustic comfort is required for residential, industrial and commercial, public and receptive use such as hospitals, homes rest and nursing homes, hotels, schools, places of worship.
The POLO-KAL 3S water drainage system can be designed according to the requirements of the design reference standard UNI EN 12056-2. According to these requirements, pipes and fittings from the POLO-KAL 3S system or other drainage systems offered by Bampi and, alternatively, BAMVENT ventilation valves can be used for the ventilation of the drainage system. In compliance with the DPCM 5/12/1997 on passive acoustic requirements inside buildings (Law in force in Italy), the POLO-KAL 3S water drainage system offers the highest soundproofing performances certified in accordance with EN 14366 at the Fraunhöfer Institute in Stuttgart.
Heavy system to be installed by means of a push-fit joining, secured by an elastomeric gasket. The connection with the socket guarantees adequate space for any expansion of the system with a reliable and guaranteed seal over time. The POLO-KAL 3S polypropylene system is compatible for connection with other plastic materials in PP / PE-HD / PVC in standard diameters.
A whole series of accessories useful for the construction of drainage systems are associated with the POLO-KAL 3S polypropylene system, including:
The special composition of the POLO-KAL 3S system determines characteristics of robustness and resistance even in critical environmental situations (rigid cold or extreme heat). Furthermore, in the event of an accident or an accidental hole, the system can be quickly repaired by heat sealing performed by an expert hand with special equipment.
