All-over 12 patterns

What it is

The pattern runs edge to edge with no reserved solid area. This group also carries the widest choice of hole: round from the smallest to the largest in the range, plus square holes and slots.

What it does

With no solid margin these are the most open faces in the special range, so they behave closest to a uniform perforation while still carrying a designed pattern. The slotted ones give the panel a direction, which reads as a linear ceiling even on a square tile.

Where it is best used

Rooms where absorption matters as much as the look: open offices, classrooms, restaurants and circulation. This group also holds the long panel formats, so it is the one to work from when the ceiling is planked rather than tiled. Where the acoustic figure is the specification, take the pattern from the uniform range instead, which publishes an open area for every one.

Special perforation is a face pattern, not a performance specification. The special sheet publishes no open-area figure for any of these. Where the acoustic number is what has to be met, work from the uniform range, which gives an open area for every pattern in it.
