Thermal Efficient Glass
High energy consumption is a main concern for commercial buildings due to bills chalked up on air-conditioning and lighting . Low Emissivity (Low E) Glass is the key solution for both comfort and cost savings. It prevents unwanted heating of interiors while still allowing as much daylight into the building as possible. The new Low E design combines maximum solar control with astonishing light transmittance and a low external reflection. There is considerable freedom when designing the façade as it is available in various thickness & sizes.
SSG offers a wide range of Low E coated solar control glass, which comes in various colours, solar control and light transmittance. A Low E coating applied via chemical vapour deposition is commonly referred to as a “hard coat”, whilst a Low E coating applied via magnetron sputtering is known as a “soft coat”. Soft coat Low E Glass perform better at thermal insulation, but are prone to oxidation upon exposure to the atmosphere. Hence, soft coat Low E Glass needs to be double-glazed or laminated with edge deletion. “Triple Silver Low E” is now available for an ideal balance of solar control and high visibility for year-round comfort, making it perfect for façades, windows and building envelopes.
Low E Glass can be used with a wide range of Design applications, and is available in tinted and Low Iron Glass or with self-cleaning functions for further cost savings.
Light to Solar Heat Gain Ratio
Low E Glass allows most of the sunlight into a building’s interiors, but minimises the entry of heat caused by the sun. This results in a high light to solar heat gain ratio.
High Visible Light Transmittance
With Low E glass, natural daylighting is possible, allowing the interior environment to be well lit without the need for artificial lighting during the day.
Low solar heat transmittance allows an effective reduction of heat radiation and occupant discomfort.
Subsequent needs for artificial lighting and air-conditioning loads are reduced, making the building more energy-efficient and environmentally – friendly.
