THE COMPLETE LOW NOISE SYSTEM – Trust what you hear
Our unique ASTRAL SILENCIO low noise system is an innovative product made of mineral-reinforced polypropylene. This base material provides excellent mechanical and acoustic properties of ASTRAL SILENCIO. Made with a high molecular structure, which enables absorption of both airborne sound and structure borne sound. Sound energy does not spread over the pipe wall.
SOUND INSULATION BASICS :
One of the most significant sources of sound within building is the sanitation setup and the accompanying drainage water pipe system. Unsuitable drainage system and type of clamping are considerable contributors to disturbing noise.
TYPICAL SOURCES OF SOUND INCLUDE :
- Fitting noises
- Draining noises
- Inlet noises
- Impact noises
A differentiation is made between Airborne noise and Structure borne noise, depending on the propagation medium.
Airborne noise : Airborne noise is present if the noises of a sound source are transferred directly through the air to human ears.
Structure borne noise : With structure borne noise, the sound transfer first through a solid body. This body vibrates and passes the vibration on to human ears as airborne noise.
APPLICATION OF LOW NOISE ASTRAL SILENCIO :
In view of the excellent mechanical and acoustic properties, this system is suitable for all fields of building construction. The best solution for high-rise buildings
- Multistorey apartment
- Sport stadium
- Educational buildings
|Area of application
|Drainage pipes in building and above the ground installation
|Modulus of elasticity
|Coefficient of linear expansion
|DIN 4102, B2
|Waste Water with ph 2-12
|Water temp. up to 95 C (intermittent) or 90 C (continuous)
Outstanding noise-insulation values :
This has been confirmed by noise measurements at the Fraunhofer Institute for building Physics, Stuttgart, Germany.
Easy installation :
Without the use of any special tools and the push fit jointing method installation of ASTRAL SILENCIO is easy, time and cost saving. Socket joint does not require solvent for jointing.
High impact resistance :
ASTRAL SILENCIO products show high impact resistance at extremely harsh temperature as low as -20 °C.
As strong as metal :
Very good alternative to metal piping like CI and others.
Chemical resistance :
ASTRAL SILENCIO can handle the waste liquid with pH value from 2 to 12. It has a high resistance to the most common chemical substances and its material nature prevents the accumulation of deposit inside the pipe.
No special clamps/hangers required :
It can be installed with the normal clamps available with ASTRAL to get the desire acoustic result.
Resistance to hot water liquid :
Hot water resistance (short term: 95° C / long term: 90° C), low linear expansion.
Smooth inner surface :
This guarantees the smooth flow and no choke up.
