The Clip-In Burgess Grille Tile has been developed for use in ventilated ceilings for the supply or extraction of large volumes of air where standard perforated tiles are inadequate. Grille Tiles are available in a range of module sizes and colours. The tiles have a standard border of 53mm and contain a central 13mm cell louvre retained in position by fixing tabs.
