Solar
Control Glass
For areas of glass under direct or prolonged sun exposure, a solar control glass will effectively reduce the amount of solar radiation from entering a space through the glass, thus reducing the overheating effect known as solar gain.
Solar gain is the effect of long wave radiation entering a space through glass and heating up internal surfaces. These internal surfaces produce short wave radiation that cannot escape a space through the glass and therefore remain inside heating up the internal environment.
Solar control glass reduces the amount of long wave radiation from entering a space, reducing overheating inside. This glass is produced by applying a coating to the internal face of a glass unit; generally face 2 of a double or triple glazed panel. The amount of solar reduction through the glass can be specified depending on what is required from the glass unit.
Modern solar control glass can still have an extremely neutral and clear appearance whilst maintaining a cool internal environment.
70% Light Transmission
Different scales of solar control glass are named by their light transmission and G-value. The G factor is the term used to describe the percentage of solar radiation entering a space though the glass generally. As the G-value reduces, so does the light transmission of the glass but London Architectural Glass can offer a solar control glass with a 70% light transmission and 41% G-value.
These glass units can be utilised in frameless structural glass assemblies like glass box extensions, glass roofs and glass walls or used within framed windows and doors.
