DAMPA DCC 200 300 e-katalog - Flipbook - Side 6
Sound Insulation
Supporting Principle
Air Injection
Room-to-room sound reduction of
41 dB - 44 dB depending on type of
insulation inlay, and from 46 dB - 50 dB
depending on type of additional insulation
overlay.
To reduce the general sound level and
reverberation time within a room the perforated
DCC Panels can be used effectively for sound
absorption.
DCC Panels with air injection slots give an even
distribution of air.
A ventilation solution which is both elegant and
cost-effective in areas where the above ceiling
space used as an air supply chamber.
These figures are the results of tests on
DCC 200/300 Plain, by an independent
test institute.
Factory Modified Panels
For projects with a large number of identical cabins, Factory Modified Adoption Panels further reduce installation time and cost
Modified Panels, Type WOF
and WF
Start Panels are specially formed narrow ceiling
panels without flanges.
They are identified by the code WOF.
End Panels are narrow versions of the standard
shaped ceiling panel.
They are identified by the code WF.
Cutouts
Type WOF & WF Ceiling Panels are available
in the following widths:
75, 100, 125, 150, 175, 200 and 225 mm.
Other widths can be made to order.
Panels with factory formed cutouts can be
supplied to specification.
For example, circular cutouts to suit downlights, speaker grilles and smoke detectors,
and rectangular cutouts to suit items such as
non-modular luminaires.
Downstands and Jointing
Ceiling levels
Joining Panel No. 2
Angle Runners No. 29
Changes in ceiling levels can be achieved in
many ways depending on the height of the
downstand and the desired visual appearance.
Joining Panel No. 2 creates a 100 mm wide
joint consisting of a 50 mm wide strip in the
ceiling panel, with 25 mm recesses either side.
This jointing method using Suspension No. 7
will also create a featured joint with a 25 mm
recess between the ceiling panels.
The distance from the ceiling panel ends to the
first carrier either side of the joining panel must
not exceed 36 mm. The distance between the
two carrier will be 172 mm.
If desired, offset the back to back
Angle Runners No. 29 to one side by 15 mm
to prevent the centre joint being visible in the
25 mm recess.
