Where normal glass surfaces usually are not really suitable for laser projections (too low reflection value), frosted glass can be a very suitable alternative. The frost effect provides sufficient reflection for the use both as front as well as rear projection solution. This kind of projection surface is often used when it comes to projections towards buildings or if certain advertisement projections shall be made. The advantage of this kind of projection surface is that it can be seamlessly integrated in most designs objects, buildings, etc., but can easily be turned into a projection "screen". The opacity and the kind of the frost effect heavily influence the suitability for laser projetions.
