Solar & Thermal
Thermally insulating glass, also known as low emissivity or low-e glass, when present within an insulating glass unit configuration provides lower thermal transmittance, and so reduced heat loss from buildings. By reducing heat loss, heating costs are also reduced.
Modern coatings, such as SGG PLANITHERM, are designed for high levels of light and solar energy transmittance, as well as thermal insulation. These products are primarily designed for the residential market.
The transmitting properties of glass also allow solar energy to be transmitted, leading to heat build-up within internal spaces. Solar control glass types can be specified where there is a need to limit excessive heat build-up, reducing the need for air-conditioning, or from the use of blinds and other shading devices to block heat, as well as light
The use of solar control glass types, such as SGG COOL-LITE, allows for larger expanses of glazing, whilst limiting the negative effects of heat build-up. Typical applications include large glazed areas in commercial, healthcare and education buildings, or conservatory roofs in residential settings.
Low emissivity and solar control coatings can be applied to, or combined with, many other products for multi-functional glazing, offering low-maintenance performance, noise reduction and enhanced safety and security.
