Used in indoor drainage installations for discharging domestic wastewater in gravity flow (where the leak-tightness test is carried out at max. 0.5 bar), where sound damping of the noise produced by water discharge is required.
Reference standard: EN 1451.
They are black, mass-colored, single-layer, made of 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 at a flow rate of 2 l/s. The sound-absorbing properties are certified following measurements carried out 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, is class B1. For penetrations through ceilings, as a measure to protect against flame spread, we recommend using fire collars.
To reduce the noise level of indoor drainage systems, the following is recommended:
• Choose a pipe and fittings system with good sound-absorbing properties;
• Ensure correct system design;
• Install the system correctly using suitable products.
