Valsir is the only company that can provide a sound insulating waste system with Silere® “ventilation branch”. This is the ideal solution in high-rise buildings where the simultaneous use factor of the sanitary appliances is high.
This innovative waste system guarantees excellent ventilation of the waste stack and branches on each floor, limiting pressure fluctuations in the system.
This system also offers significant advantages and money savings thanks to the possibility of constructing single stacks (therefore without the need for parallel ventilation) of a 110 mm diameter with a draining capacity that is more than double that of systems with primary ventilation.
One soil stack, no separate ventilation pipes required.

Silere® ensures practical and rapid installations without the use of glues, electrical appliances or special tools, thanks to the jointing system with push-fit socket.
The particular shape of the seal and the housing of the push-fit joint guarantee hydraulic tightness and allow the normal movements of the pipe including those caused by thermal expansion.
To allow use of leftover pieces of pipe, Valsir supplies a bi-joint sleeve: a special fitting that allows two pipes without sockets to be connected together, guaranteeing hydraulic tightness without compromising flow rates.
The range is made up of pipe lengths between 150 mm and 3000 mm and is characterised by a wide choice of fittings and accessories that allow the most varied system configurations to be created
From diameters 58 mm and 78 mm for the creation of branches for each floor, to diameters 135 and 160 mm for waste manifolds.
These particular pipe sizes are due to the large wall thickness and the need for a sufficient bore passage; thanks to the special connection and transition fittings, it is possible to connect the Silere® system to other waste systems made of different materials.
The range is completed with accessories for connection to other waste systems produced by Valsir and pipe clips with anti-vibration rubber to reduce the vibrations that are transferred to the installation walls when the waste system is in operation.
Wide range of diameters from DN 50 mm to DN 160 mm.
Surface mounting of pipes requires the use of suitable brackets that must withstand the weight of the pipe, the weight of the waste water and the forces that are generated by expansion and contraction. In relation to the type of bracketing chosen, the so-called guide points and fixed points (or anchor points of the pipeline) must be provided.
In all cases, if the waste system is required to reduce noise then sound reducing brackets with anti-vibration rubber must be used.
If the waste system is constructed using Triplus® or Silere® then the employment of sound insulating pipe brackets is essential.
Valsir is the only company that can provide a sound insulating waste system with Silere® “ventilation branch”. This is the ideal solution in high-rise buildings where the simultaneous use factor of the sanitary appliances is high.
This innovative waste system guarantees excellent ventilation of the waste stack and branches on each floor, limiting pressure fluctuations in the system.
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.
The reference standards used to evaluate the performance of waste systems in the laboratory and which specify the measurement methods are DIN 4109 (together with DIN 52219) and EN 14366.
Both standards require the use of a test building composed of four floors with a concrete wall onto which the waste stack is anchored.
The measuring floors are divided into two rooms: the front room is where the waste stack is installed, the rear room is free of installations and receives the sound vibrations that are transferred from the partition wall. The values measured can be expressed using different indicators according to requirements and the reference standards.
LSC,A is the indicator required by EN 14366 and indicates the structure-borne noise level, whereas LIN is an indicator that also encompasses the air-borne noise required by DIN 4109.
It’s not important which indicator is the most effective, however, when comparing different waste systems it is of vital importance for a fair comparison that the same indicator is used.
The real noise levels produced by a waste system can only be measured when it is in operation, in that it depends on numerous factors such as the installation and the building type; laboratory indicators should be used only as a means of comparison.
Silere® is a push-fit system composed of pipes, fittings and accessories, industrialized, produced and patented by Valsir, that is capable of guaranteeing the lowest levels of noise on the market today
The pipes and fittings are produced with a mix of polypropylene and mineral fillers that guarantees high mechanical resistance, excellent acoustic performance and high resistance to agents.
Silere® pipes and fittings are made of a patented polypropylene-based mix (PP) and mineral loads (MF) that provide high mechanical characteristics and at low (impact resistance at -20°C) and high temperatures (at a continuous operating temperature as high as 95°C).
The Silere® waste system can transport waste liquids with PH values between 2 and 12, it has a high resistance to the most common chemical agents and is characterised by an extremely smooth surface, such as to prevent the accumulation of deposits inside the waste pipework.
Measured in the Fraunhofer laboratory of Stuttgart, in compliance with EN 14366, equal to 6 dB(A) with a flow rate of 2 l/s (certificate P-BA 223/2006).
Resistance to intermittent discharges at temperatures as high as 95°C. High impact resistance at extremely harsh temperatures as low as -20°C.
High chemical resistance to the substances dissolved in civil and industrial waste systems.
Without the use of any special tools, thanks to the push-fit jointing method. Also the socket joint doesn’t require the extra use of harmful glues or solvents.
Wide range of diameters from DN 50 mm to DN 160 mm.
Wide range of transition fittings for connection to other waste systems such as cast iron, PE, PP, PVC.
The product, its recyclability and the production processes are based on Green Building principles which promote respect for the environment and the conservation of natural resources.
The range is made up of pipe lengths between 150 mm and 3 m and is characterised by a wide choice of fittings and accessories that allow the most varied system configurations to be created.
From diameters 58 mm and 78 mm for the creation of branches for each floor, to diameters 135 and 160 mm for waste manifolds.
