It is used in internal sewage systems for the discharge of domestic wastewater under non-pressure flow conditions (where the leak test is performed at max. 0.5 bar), especially for building risers, where sound attenuation of water discharge from upper floors is desired.
Reference standard: SR EN 1329-1.
The white pipes are manufactured by co-extrusion from PVC-U with mineral additives, featuring a triple-layer wall construction, and are equipped with a socket and rubber seal at one end.
The range of dimensions includes diameters from 50 mm to 200 mm, with lengths between 250 mm and 3000 mm.
The acoustic performance is 11 dB for a flow rate of 2 l/s. The sound-absorbing properties are certified following measurements conducted at the Fraunhofer Institute laboratories in Germany, in accordance with EN 14366. The use of sound-absorbing clamps is recommended.
The fire behavior classification of the piping, in accordance with SR EN 13501, falls into class C – s3 – d0. The material is fire-resistant and self-extinguishing once the fire source is removed. Unlike other internal drainage materials, PVC-U is inherently flame-retardant, eliminating the need for additional fireproofing. When passing through ceilings, we recommend using fire collars as a protective measure against flame propagation.
To reduce the noise level of internal drainage systems, we recommend:
• Selecting a system of pipes and fittings with good sound-absorbing properties;
• Ensuring correct system design;
• Installing the system correctly using appropriate products.
