This product is used in indoor sewage systems for the discharge of domestic wastewater under non-pressure flow conditions (where the leak test is performed at max. 0.5 bar), specifically where sound attenuation from water discharge is desired.
Reference standard: EN 1451.
These are black, mass-colored, single-layer pipes made from PP with mineral additives.
The size range includes diameters from 32 mm to 160 mm.
The socket and gasket jointing system requires no special tools, adhesives, or solvents.
Acoustic performance is 16 dB for a flow rate of 2 l/s. The sound-absorbing properties are certified by measurements conducted at the Fraunhofer Institute in Germany, in accordance with EN 14366. The use of sound-absorbing clamps is recommended.
Fire behavior classification, in accordance with DIN 4102-1, is B1. When passing through ceilings, we recommend using fire collars as a protective measure against flame propagation.
To reduce the noise level of indoor drainage systems, we recommend:
• Selecting a pipe and fitting system with good sound-absorbing properties;
• Ensuring correct system design;
• Installing the system correctly using appropriate products.
