This product is utilized in indoor drainage systems for domestic wastewater discharge in gravity flow applications (where the leak test is performed at a maximum of 0.5 bar), specifically where sound attenuation from water discharge is desired.
Reference standard: EN 1451.
These are black, mass-colored, single-layer, and made from PP with mineral additives.
The size range includes diameters from 32 mm to 160 mm.
Socket and gasket joint system; no special tools, adhesives, or solvents are required.
Acoustic performance is 16 dB for a flow rate of 2 l/s. The sound-absorbing properties are certified following measurements conducted at the Fraunhofer Institute in Germany, in accordance with EN 14366. The use of sound-absorbing clamps is recommended.
The fire behavior classification, in accordance with DIN 4102-1, falls under class B1. For protection against flame propagation when passing through ceilings, we recommend using fire-resistant clamps.
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.
