Round perforation

Ø2.3mm

15.8% open area

The middle of the range, and where most ceiling specifications land. Visible perforation with a substantial open area behind it.

The standard hole. Thirteen patterns from 1.8mm up to 10mm, in straight and staggered grids.

Specifying this pattern

Name it as Ø2.3mm at 15.8% open. The size alone is not enough to identify a pattern: this range holds two patterns at 1.8mm, two at 2.3mm, two at 2.5mm, two at 3mm and two at 5mm, and within each pair only the open area differs.

Perforation is available plain or perforated on our panel systems. Whether this pattern can be run on a particular panel depends on the panel size and its edge detail, so confirm it with us before it goes in a specification.

Same hole, different open area

The pitch changes, the hole does not. Usually the direct alternative when the look is right but the acoustics are not.
