Used in internal drainage systems for the discharge of domestic wastewater under non-pressure flow (leak test performed at max. 0.5 bar), where sound attenuation of water discharge is desired.
Reference standard: EN 1451.
These are black, mass-colored, single-layer, made from PP with mineral additives.
The size range includes diameters from 32 mm to 160 mm.
Socket and gasket jointing system; no special tools, adhesives, or solvents are required.
Acoustic performance is 16 dB for a flow rate of 2 L/s. Sound-absorbing properties are certified by measurements conducted in the laboratories of 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, falls into class B1. When passing through ceilings, we recommend using fire-resistant clamps as a protective measure against flame propagation.
To reduce the noise level of internal drainage systems, the following are recommended:
• Selecting a pipe and fitting system with good sound-absorbing properties;
• Ensuring correct system design;
• Correct installation of the system using appropriate products.
