This means the stretched ceiling can improve not only the inner acoustic properties of the room, but change its acoustic insulation in horizontal and vertical planes due to creating of “an air cushion.”
Vertical acoustic insulation
Irrespective of the building structure of multistory buildings and regardless the flooring width between levels, we hear the noise “from above” more frequently than we would like to. In this scenario a stretched ceiling can become a reliable barrier to sound waves and drown outer and inner noise.
Sources of external noise in a room:
working things installed in the gap between the concrete floor and the stretched ceiling (e.g. air ducts);
operating technical, household and other devices located on the upper floor;
impact or airborne noise in the rooms in the upper floor.
Sources of internal noise, which may be necessary to keep inside the room:
operating technical, household and other devices;
impact or airborne noise in the room.
Horizontal acoustic insulation
Acoustic insulation between adjacent rooms is high on the agenda if the working or office space is divided into studies or cubicles by light partition walls.
However, this structure cannot ensure the same degree of acoustic insulation that can be achieved in rooms with partition walls reaching the concrete ceiling and adjoining it.
Thus, acoustic properties of the stretched ceilings enable to apply them when designing musical and TV studios, concert halls, theaters and movie theaters, laboratories, musical classes and lecture rooms.
However, one should not forget that the optimal acoustic parameters of the room cannot be achieved only by installing a stretched ceiling: one should also consider special finishing for the walls, floors, the materials to be used and technical specifications of the windows, doors, positioning of the loudspeakers, etc.
The motive to use this material is very simple. Make your business more attractive, quitter, comfortable and esthetically magnetic and unique.
Intense decrease of the sound level in reverberative rooms. Combined with Isover-glass wool:
- aw = 1 – sound absorbing class A
Acoustic adjustment and sound insulation:
Combined with a plaster board and Isover-glass wool (4 inches thick) for sound insulating walls, partition walls, etc.:
- aw = 1 – sound absorbing class A,
- Rw higher or equal 35 dB.
Improved sound insulation:
The acoustic system contributes to a better sound insulation of the walls as well as a smaller transmittance of airborne and impact sounds. Additionally it affords a brilliant acoustic adjustment.
You can create an ambience that you wish and attract more customers that will appreciate your care.
