Used in indoor drainage systems for discharging domestic wastewater in gravity flow (where the leak-tightness test is carried out at max. 0.5 bar), where sound damping from water discharge is required.
Reference standard: EN 1451.
Black, through-coloured, single-layer, made of PP with mineral additives.
Socket-and-gasket jointing system; no special tools, adhesives, or solvents required.
Size range includes diameters from 40 mm to 110 mm.
Acoustic performance is 16 dB at a flow rate of 2 l\/s. The sound-absorbing properties are certified based on measurements carried out in the laboratories of the Fraunhofer Institute in Germany, in accordance with EN 14366. The use of sound-absorbing pipe clamps is recommended.
To reduce the noise level of indoor drainage systems, it is recommended to:
\u2022 Choose a pipe and fittings system with good sound-absorbing properties;
\u2022 Ensure correct system design;
\u2022 Install the system correctly using suitable products. <\/p>\n","protected":false},"excerpt":{"rendered":"
