Polypipe Building Products Poly-dB® Acoustic Soil System combines the familiarity and advantages of standard ring seal soil systems, with proven enhanced acoustic performance. Our range of socketed pipe and ring seal fittings in combination with vibration damping brackets ensures that the system not only meets but surpasses current building regulations requirements for sound insulation.
Our Poly-dB® soil pipe is manufactured with a hydraulically smooth inner surface, which allows for a continuous smooth flow of water, reducing sound emissions. The system comes complete with a range of acoustically engineered fittings to ensure fast and easy drainage installations for soil and rainwater applications.
The Benefits
- Excellent sound insulation 12 dB(A) at flow rate 2l/s*
- Elevated impact resistance
- Resistance to a wide range of chemical agents at high temperatures
- Easy to install
- LABC Approved
*Test EN 14366 / DIN 4109
Polypipe Building Products Poly-dB® soil system is suitable for all gravity waste water pipes in accordance with DIN EN 12056 and DIN 1986-100. Pipes and fittings consist of mineral-reinforced polypropylene, which as well as offering impressive acoustic properties also offers improved temperature properties versus standard PVC soil systems.
The consistently thick-walled pipes and fittings meet the raised requirements of Sound Insulation Class III of DIN 4109 / VDI 4100. Just as with all synthetic materials, Polypipe Building Products Poly-dB® is corrosion-proof, long lasting and resistant to chemically aggressive waste water in the range of pH 2 to pH 12. The smooth inner surfaces and high degree of resistance to abrasion make sure that no deposits develop and this, in turn, ensures that the pipes can be reliably operated for a very long time.
Sound Insulation
Tests conducted by the Fraunhofer Institute in accordance with DIN EN 14366 confirmed the excellent sound insulation properties and the maximum Sound Insulation Class III requirements. It has been proven for many years now that thickwalled pipe systems with very high molecular weight minerals have excellent sound insulation properties. The high density of 1.6 g/cm3 (+/- 0,05) contributes to the absorption of sound which is transmitted by air and conducted by solids.
The sources of noise in building service installations are:
- Filling noises
- Intake noises
- Noises from fittings
- Draining noises
- Impact noises
