Installation guides.

Most trimless lighting problems are created or avoided on site. These installation guides cover the sequence of works, coordination between trades, fixing and ceiling preparation, wiring and driver positions, and the checks that should happen before ceilings are closed. They are written for contractors, site managers and designers who want a clean result first time.

All installation guides

• How trimless lighting is installed, step by step — Trimless lighting is installed by fixing a plaster-in profile to the ceiling board or framing, taping and skimming it in, decorating, then fitting the light engine and diffuser.
• Trimless lighting: getting the installation sequence right — A clear sequence of set out, profile fixing, first fix, plastering, decoration and second fix is the key to flawless trimless lighting.
• Trimless lighting in plasterboard ceilings — Plasterboard ceilings are ideal for trimless lighting; profiles fix to the board or framing and are skimmed in, with extra support where runs are long.
• Preventing cracks around trimless lighting — Cracks around trimless lighting are prevented with secure fixing, jointing tape, proper skim thickness, movement joints on long runs and avoiding early heat stress.
