System 9000N
- Adjustable height 80 – 450 mm, excl. floor covering
- 25mm, 50mm dampening element
- Suitable for projects with extreme sound requirements
A subfloor system made of steel that provides effective structure-borne, impact and airborne sound insulation for premises with high acoustic requirements, such as concert halls, theatres, cinemas, studios, music practice rooms, gyms, dance halls and server rooms. Many premises have higher requirements for structure-borne sound than that of residential buildings. This includes premises which require freedom from disturbances and disruptions or activities that generate a great deal of vibrations and noise through the supporting slab and structure. In these cases, normal solutions may be room-in-room construction or the casting of liquid screed floors.
We have developed an innovative, flexible system offering new possibilities. System 9000. We have based this on requirements established by acousticians on natural frequency in floor systems. With a unique range of sylodyn damping elements, you can customise your floating floor or room-in-room construction based on floor loads and preferences for natural frequency.
