– Superior sound insulation in DIN 4109 norm.
– Multi-layer manufacturing technology
– High resistance to corrosion and excellent resistance to chemicals
– Ease of transportation and maintenance with telescopic stowage method
– Ease of combination and installation
– %100 impermeability due to unique seal design
– Long life
– Smooth flow surface
– Flexibility
– Opportunity of production in any desired length.
– High temperature resistance (short-term 110 S04; C)
– Does not leave toxic gas during fire
– High resistance to corrosion
– Superior impact resistance even at 0 S04; C


– Silenta prevents the hearing of the noise formed by the impact of the waste in the internal surface of the pipe with high moleculer weighted special formulla and 3-layer structure.
– Special structure of Silenta reduces the vibrations on the installation system substantially. Thus, the contact noise and roaring occured as a result of the vibration inside the building is prevented.
– Also contributes to an increase in the value of the property.
