Solar Control Glass For Energy Efficiency In Buildings
Solar control glass is a hi-tech product developed by the glass industry to allow sunlight to pass through a window or façade while radiating and reflecting away a large degree of the sun’s heat. The indoor space stays bright and much cooler than would be the case if normal glass were used.
Solar control glass is not necessarily coloured or mirrored glass, although such finishes can be applied for aesthetic purposes if desired. It incorporates invisible layers of special materials on the glass which have the dual effect of allowing sunlight in, while repelling solar heat. Solar control glass units are typically doubleglazed, which means they also insulate well.
Solar control is a key issue in terms of energy saving:
- In hot conditions, or for buildings with high internal loads, it is used to minimise solar heat gain by rejecting solar radiation and help control glare
- In more temperate conditions it can be used to balance solar control with high levels of natural light.
How do you choose Solar Control Glass?
Advanced solar control glass provide superior performance – higher light transmission, reduced visual glare, lower reflection and wide spectrum of colors to choose from.
While selecting this kind of glass, two values should be noted - u value and solar factor. U Value is a measure of how much of heat gain is reduced due to temperature difference between the exterior and interior of the building. The lower the value- the better the heat reduction.
Solar factor determines how much of direct heat from the sun can be filtered. The lower value it has, the better the filter.
Where can you use Solar Control Glass?
Basic Solar Control Glass finds its applications in windows and doors and advanced solar control glass is widely used in glass skylights and glass facades.
