System 9000N – For extreme sound insulation requirements

For adjustable height 70 – 140 mm, excl. Floor covering.

A structure-borne noise insulating system for premises with strict requirements, e.g. concert halls, theatres, cinemas, studios, music rehearsal rooms, gyms, dance venues and server rooms. Many premises have more stringent requirements for structure-borne sound insulation 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.
In these cases, normal solutions may be room-in-room construction or the casting of liquid screed floors.
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.

Examples of areas of use:

• Concert halls, theatres and cinemas
• Studios and music rehearsal rooms
• Gyms and dance venues
• Server rooms

The system can be fully adapted to the needs of your premises.

You decide:
• The height of the system
• Requirements for natural frequency
• Design of floor surface
• Load type and requirements
• Floor covering above the system

Weight of surface flooring and additional loads.

By having relatively heavy surface flooring, you can achieve low natural frequency and you are able to retain capacity for additional loads.
If additional loads are significantly heavier in relation to the dead load of the floor, resonance frequency in empty premises may be more difficult to bring down to the preferred natural frequency. A solution for this can be heavier loaded flooring.
