A solar control glass is a glass with a special coating designed to reduce the amount of heat entering a building. It reflects and absorbs heat as well as filters light from windows and doors for reduced glare. Using a solar control glass reduces the need for air-conditioning and blinds.
The solar factor measures the percentage of heat that passes through the glass. The lower the solar factor, the higher the solar protection and the performance of the solar control glass.
Solar control glass is used to prevent excess heat build-up in areas where large amounts of heat and radiation are present. For example glass roofs, south-facing elevations. The choice of product then depends on the level of performance and appearance requirements. E.g. Very reflective, coloured, neutral.
The U-Value of a window is a measurement of the rate of heat loss indicating how well your windows are keeping valuable heat in. It is expressed as Watts per square metre Kelvin W/m2K. The lower the U-Value, the better the thermal performance of the glass. 'Low-emissivity' or 'Low E' glass offers improved thermal insulation denoted by very low U-Values.
Toughened glass is up to five times as strong as ordinary glass which means that it has to be hit much harder in order to break. Even when it does break, it breaks into lot of small pieces which are much less dangerous. Laminated glass has the same strength as ordinary glass, but it consists of two pieces of glass with a sandwich of a plastic interlayer. If the glass does get broken, this interlayer holds the whole piece in place. Laminated glass is used for safety and sound insulation.
Safety glazing should be used in low level glazing, glazing in and around doors, overhead and in large areas of glazing to prevent injury following accidental glass breakage.
