RAUPIANO PLUS 17dB
RAUPIANO PLUS fulfils the highest requirements on sound protection to VDI 4100 and largely avoids disruptive flow noises. With sound levels below 20 dB(A), the system already fulfils tomorrow's requirements today.
- Three functional layers ensure safer drainage, absorb sound and ensure safe installation even at -10 °C
- Hydraulically-optimised mouldings ensure maximum drainage performance and less flow noise.
- Special patented fixing clamps break down the structure-borne sound effectively
- Reinforced wall bends provide weight where it is most important for minimising sound
