Colours are dyed fabric, so screens and print will differ. Ask for the physical swatch card before you specify. A paintable white face is available when you need an exact paint match.

Fabric wrapped panel, bevel edged. The standard Flexi™ edge. A small chamfer softens the panel outline and reads well in grids with even reveals.

Fabric wrapped panel, straight edged. A square, crisp edge for tight-butted runs and full-wall layouts.

Or print anything

Your artwork, logo or photo printed on the panel face.

Fixing methodsClips and adhesive, mechanical, flush ceiling, suspended cloud, track

Wall, no drilling. Impaling clips and adhesive. Clean and quick on painted plaster and board.

Wall, mechanical. Clips screwed to board or masonry where adhesive is not suitable.

Ceiling, flush. Fixed tight to the soffit with helical anchors, four per panel.

Ceiling, suspended cloud. Hung about 100 mm below the soffit on four spring and wire sets, one per corner.

Fabric system. Perimeter track on the wall or ceiling, fabric stretched over the infill.

  • Panels go on solid walls and ceilings only. We do not fix to glass, windows or demountable partitions.
  • Ceilings above 3 m need mobile scaffolding. We plan this in the quote.
  • We keep clear of sprinklers, detectors, diffusers and lights, and model every fixture in the 3D layout first.
