SilereSoundproof
Excellence in soundproofing performance.
When a waste system is in operation, noises originate inside the pipework which vibrates due to the fall of the liquid being discharged.
Most of the noise propagates inside the pipe, however, the vibrations generated are transmitted from the walls of the pipe to the surrounding area, to the pipe anchoring system and consequently to the building structure.
To control the levels of noise created by waste systems not only requires the correct design of the system and clearly the correct installation but also the tidentification of a waste system that will guarantee a high soundproofing performance.
Silere® is a top sound insulating product that was designed with the aim of providing high performing sound insulated waste systems, in fact, with a waste flow of 2 l/s (represents the typical discharge rate of a WC) noise levels of 6 dB(A) were measured.
Waste systems with excellent acoustic performances
6 dB(A) rumour levels with a 2 l/s WC flow rate.
The measurement of the soundproofing performance of waste systems
The reference standards used to evaluate the performance of waste systems in the laboratory and which specify the measurement methods are German Standard DIN 4109 (together with DIN 52219) and European Standard EN 14366. Both standards require the use of a four-storey building with an inside wall in concrete to which the waste stack is anchored.
The measurement floors are divided into two rooms: the front room is where the waste stack is installed, the rear room has no pipes running through it but receives the sound vibrations in the partition wall. The values measured can be expressed with different indicators depending on requirements and the reference standards.
LSC,A is the indicator required by EN 14366 and indicates the structural-borne noise level transmitted whereas LIN is an indicator that also takes air-borne noise into consideration required by DIN 4109.
It doesn’t matter which indicator is more important, the aspect that needs to be taken into consideration is that in order to compare different waste systems the same indicator must be used.
The actual noise levels of a waste system can only be measured on site, in that noise emissions depend on numerous factors, such as the installation and the type of building; laboratory indicators are only to be used as a means of comparison.
