Overhead Demonstration Mirror Here is another great example of how the Mirrorlite®glassless mirror can be used beyond the practical limitations of glass or plastic mirrors. Our glassless mirrors are frequently used as cooking demonstration mirrors thanks to many great features. They are UL commercial fire rated. Since Mirrorlite®glassless mirrors weigh less than 1/2 pound per square foot they can be easily and safely mounted at any angle or position without fear of collapsing or shattering. They reflect an image that is bright, clear and free of distortion due to their front reflective surface design and super flat and rigid construction. Unlike glass or plastic mirrors that require frequent cleaning, Mirrorlite®glassless mirrors are non static in nature and therefore do not attract dust and particulates, making the need for cleaning practically non-existent.
