Perforated Gypsum Board
Perforated Acoustic Gypsum Board | Crisp and Clear Acoustics | Chennai


Acoustic Perforated Gypsum Board is designed on the basis of Helmholtz resonance theorem, after perforated, the holes, board, and the wall make up of many resonant cavities, when air molecules pass the holes, the resonant cavities will consume large quantities of sound energy.


Acoustic Perforated Gypsum Board has been designed for use on ceilings and walls where an increased level of sound attenuation is required. Acoustic properties of the board are achieved by perforations of the board surface that absorb sound to reduce echoes and reverberation. The long edges of the panels are recessed for flush jointing to a smooth, continuous surface. Acoustic perforated gypsum board is one of the best sound absorption products, it is widely used in Auditorium, Library, Office, Cinema, Church, Hospital. School, Exhibition, Studios, and so on.

Perforation Variants (Square hole)

Our high-density acoustic perforated gypsum board comes in a variety of perforations and sizes to meet your architectural goals. They consume large quantities of ambient sound energy creating significantly quieter atmospheres for any space where the listening or learning environment is critical. Acoustic perforated gypsum panels come in many perforation designs ranging from Circle, Square & Capsule-shape. The perforated board absorbs sound that would otherwise reflect back into the room.

Painting and Decoration

Finishes applied to acoustic perforated gypsum board surfaces can have a significant effect on the perceived quality of the installation, particularly where critical lighting conditions exist.

  • Textured or heavily patterned finishes tend to hide imperfections

  • Matt finishes minimizing imperfection visibility

  • Semi-gloss and gloss finishes highlight imperfections

  • Light colours are less likely to show imperfections and impact damage
