Soundproof waste and drainage system

Soundproof waste and drainage system inside the buildings.
Over recent years there has been an increase in the attention given to the emission of the noise generated inside buildings, involving various aspects such as urban planning, construction techniques, the layout of rooms and the soundproofing of systems.
Respect of the conditions of acoustic well-being of homes, as well as the workplace and public venues, has become an essential requirement of buildings.
Silere® is a push-fit system composed of pipes, fittings and accessories, is industrialized, produced and patented by Valsir and meets these requirements guaranteeing the levels of silence of waste systems as required by the laws and regulations in force.
Silere® is produced in compliance with EN 1451 and can be used for low and high temperature waste systems, for waste network ventilation systems and for rainwater drainage systems inside the buildings, for civil and industrial use, hospitals and hotels.
The wide range of pipes, fittings and accessories allows an entire waste system to be constructed: from the branches to the sanitary appliances, the stacks and waste manifolds.

Further details
Performance without compromise
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.
Excellent soundproofing performances
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).

Extreme Temperatures
Resistance to intermittent discharges at temperatures as high as 95°C. High impact resistance at extremely harsh temperatures as low as -20°C.

Chemical resistance
High chemical resistance to the substances dissolved in civil and industrial waste systems.

Speed and ease of installation
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.

from DN 50 mm to DN 160 mm
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.
A range that stands out
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.
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.
Push-fit joint: rapid and easy installation.
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.
The bi-joint sleeve to reduce wastage to a minimum
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.
Solutions for all requirements.
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.
The ideal solution for high rise buildings
One soil stack, no separate ventilation pipes required.
Increase in stack load
in comparison with conventional systems.

Reduction in speed
of effluents.

Excellent ventilation
of the stack and branches of each floor.

Up to 6* connections on one branch fitting
allacciate alla stessa braga.

Up to 45** flats
on connected to the same soil stack.

* The side connections of the Silere® ventilation branch are created in the factory according to project specifications.

** The number of apartments depends on the composition of the same.
The same diameter is up to 2.2 more performant
Accessories for all installation requirements
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.
