Cut outs may be made for light fixtures and their bezels but will need to be properly supported from above. Use a utility knife or sharp tipped scissors. The material cuts like light cardboard. We recommend not placing any weight on top of the tile. Their light weight and 3D shape allows them to sit in the grid but cannot support any added weight. Cut outs made for sprinklers should be a minimum of 1/4” larger than the outer diameter of the trim ring/escutcheon to enable tiles to fall from the ceiling grid without becoming entangled with the sprinkler or interfering with its operation during a fire. With all of our designs, lighting will require some experimentation to maximize the impact of the installation.
