Designed for indoor gravity-flow domestic wastewater drainage systems (leak tested up to 0.5 bar) where sound attenuation of water discharge is desired.
Reference Standard: EN 1451.
These are black, integrally colored, single-layer, and made from PP with mineral additives.
Available in diameters ranging 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 at the Fraunhofer Institute in Germany, in accordance with EN 14366. The use of sound-absorbing pipe clamps is recommended.
Fire behavior classification, according to DIN 4102-1, is B1. For fire propagation protection when passing through ceilings, we recommend using fire-resistant pipe clamps.
To reduce noise levels in internal drainage systems, we recommend:
• Selecting a pipe and fitting system with good sound-absorbing properties;
• Ensuring correct system design;
• Correct installation using appropriate products.
