Clear glass differs from other types of glass by its basic raw material composition. In particular, this glass is made with a very low iron content in order to minimize its sun reflection properties. It therefore lets as much light as possible through the glass. It is most particularly of use for solar energy applications where it is important that the glass cover lets light through to reach the thermal tubes or photo-voltaic cells.
Anti-reflective properties can be further increased by applying a special coating on the low-iron glass. It can also be used in windows or facades as it offers excellent clarity, which allows occupants to appreciate true colours and to enjoy unimpaired views.
