Special perforation · Radial

Pattern 142

Rays, fans and rosettes worked out from a center point, usually inside a square or diamond border. Every one of them is run at the largest round hole in the special range, so the figure holds together when it is read from floor level rather than dissolving into grey.

The design is centered on the tile, so it repeats once per panel and the ceiling reads as a grid of medallions rather than one continuous field. Each panel keeps a solid margin around the figure, which means a radial face is less open than an all-over pattern punched at the same hole size. Where radial patterns suit.

Specifying pattern 142

Name it by its number. These patterns have no names in the catalog, and the number is the only identifier that will match what we hold. Give the panel size and, where the pattern offers more than one, the hole diameter you want it run at.

Special perforation is a patterned face, not a performance specification. Where the acoustic figure is what matters, work from the uniform range, which publishes an open-area percentage for every pattern.
