Stay Protected With Solar Control Glass

Solar control glass reduces heat gain while allowing in a large amount of natural light.  Solar control glass covers all architectural requirements, offering solutions for large and small glazed areas of all types of buildings. Due to these benefits solar control glass can be best used to provide comfortable environments to live and work.

Architecture in modern times is characterized by spaciousness and transparency. Large windows have become a feature in recent constructions which help merge the exterior with the interior and also facilitate a great deal of light entering a building’s interior, thereby avoiding excessive use of artificial lighting.

Early versions of solar control glass or sun protective glass was based on glass coloured in a compound. Compared with clear glass, coloured glass increases solar radiation absorption, but it also has a significant effect on the transmitted visible light. As monolithic glass, it reduces the transfer of energy to approximately 60 %, and in insulating glass, combined with a normal pane of clear float glass; it reduces the solar energy transmission to approximately 50 % when the coloured glass thickness is 6 mm. The thicker the glass, the higher the energy absorption and the lower the transmission. Green, grey and bronze-coloured glass is most frequently used. Due to their own inherent colouring, they can significantly change the way interior colours are perceived. Advances in glass coating technology have produced a much broader range of colours that are also considerably more neutral in terms of the effect they have on interior colours.

Modern insulated glass allows short wave solar radiation to pass through without hindrance, but the majority of short wave heat radiation is reflected. This results in solar heat gain in the cold seasons. ln summer, however, this solar radiation can result in overheating. In addition to other energy sources, the position and size of the glazing is critical. In general, windows or façades with large areas of glazing that face east, west and, especially, the south should be equipped with suitable sun protection glazing.

In addition to actual solar protection, which is constantly being refined, a great deal of research and development effort is invested in optimising storage life, processing and resistance to mechanical influences. Another essential requirement with regard to coating is to supply versions for all products that can be laminated, tempered and bent. Only through these parameters can the broad spectrum of modern architecture be addressed in every aspect. The trend today is toward design oriented façades, which entail new designs in solar control glass. Glass with low outside reflection can be manufactured, depending on the coating that is used. Glass façades can be built to neutralise the visible borders between inside and outside, yet remain energy efficient. On the other hand, there are mirroring or colour-reflecting coatings that allow for some architectural license, including realising unconventional design concepts. Such creative and additive glass designing is generally project-related and feasible once the physical construction rules have been taken into consideration. Digital or screen print techniques are available, along with laminated safety glass. Colour-coordinated balustrades, for example, enlarge the range of solar control glass.

The range of glass solutions available these days is large and can be manufactured depending upon the architectural requirements. Reducing the phases of artificial light also benefits and has a positive impact on the environment as a result.
