Gustafs Standard perforation patterns

Perforated PanelsGustafs Standard Perforations

Our various acoustic patterns are tested and documented to achieve known sound absorption coefficients for both walls and ceilings.
It is also possible to create your own perforation pattern.

Measurement guide

**Normally C = 25-35 mm.
When group perforation B and C = 25-95 mm. A and E = constant.
