PERFORATIONFeatures and pattern
zone layouts
One of the main aspects of a metal ceiling is
sound absorption; this can be appropriately achieved
through its perforation.
Various types of perforation designs are available;
both standard and decorative.
The main function of the perforated ceiling surface is
to achieve acoustic control of the pressure sound waves.
Equally important is the unique
decorative opportunity a perforation pattern offers.
To reach the required optimal acoustic levels,
the perforated ceiling panels can be supplied with a
black acoustic fleece sound absorbing membrane
bonded to the concealed surface.
Perforation Typesfor DAMPA Steel and Aluminium Ceilings
Dampa offers a wide range of perforation types in various patterns.
Our computer controlled presses are both precise and flexible; they can even handle the creation of plain areas in the middle of a perforated surface.
