For use in internal drainage systems for the discharge of domestic wastewater under gravity 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 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 for a flow rate of 2 l/s. Sound-absorbing properties are certified by measurements performed in Fraunhofer Institute laboratories in Germany, according to 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 the use of fire-resistant clamps as a protective measure against flame propagation.
To reduce the noise level of internal drainage systems, we recommend:
• Selecting a pipe and fitting system with good sound-absorbing properties;
• Ensuring correct system design;
• Correct installation of the system using appropriate products.
