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:
Good solar control performance with low light reflectance ensures comfortable interiors at a reasonable price. The low-emissivity property provides additional thermal insulation, which makes the product both energy- and cost-efficient through a reduced need for lighting, heating and cooling.
The clear glass and natural aspect of the good performance coating provide medium light transmittance and low light reflectance for undistorted, natural views.
The durable on-line coating makes the product easy to handle and process. The product can be laminated, toughened, bent and enamelled using standard techniques. It can be used in its monolithic form or incorporated in an IGU and has an unlimited shelf-life. No edge deletion is required.
The colour remains stable whether toughened or annealed.
The stability of the coating, even after heat treatment, reduces lead times and production losses when toughening is required.
