HARD COATED LOW-E GLASS BY OFFLINE PVD A special architectural energy-saving glass by CS Eco Glass

Glass is one of the oldest materials in the building industry. It is known for its beautiful, versatility and available in many aesthetically pleasing sizes and styles – thus, offering virtually limitless design possibilities.

Since the beginning of 20 th century, modern architecture has been instrumental in the mass production of concrete, glass and steel structures in cities around the world. Glass and steel construction are the epitome of development in many countries, where these buildings are seen as symbols of affluence and luxury.

Being the largest glass processor in Malaysia, CS Eco Glass (M) Sdn Bhd is renowned for pushing the envelope whenever they develop new solutions for various residential and commercial projects. A subsidiary of Kibing Group, CS Eco Glass specialises in producing and supplying various types of float glass and architectural energy-saving glass including Low-E coated glass.

HARD COATED LOW-E GLASS BY OFFLINE PVD

Low-Emissivity (or commonly known as Low-E glass) coatings are manufactured with Vacuum Sputtering technology, sprayed on fine floated glass with multi-layer of metal coating to prevent solar infrared thermal transmittance and provide ideal summer heatinsulation performance; higher visible light transmittance to ensure adequate natural light indoor; and lower heat transfer coefficient and better heat preservation in winter.

CS Eco Glass manufactures various types of Low-E glass including the Hard Coating Low-E (Off-Line). Hard Coating Low-E (Off-Line) does not have a layer of Ag (Silver) like the traditional Low-E glass but instead, coated with a layer of transparent conductive Non Ag Low-E or commonly known as Indium Tin Oxide (ITO).

ITO is a single-side coating where the coated surface is conductive and another surface is insulated. In this approach, there is passivation layer of silicon dioxide (SiO 2 ) in between ITO layer and borosilicate glass surface; the passivation layer is essential to increase the quality as well as longevity of ITO coated glass plate. Further, the uniform thin layer of Indium tin oxide over a glass substrate makes it highly transparent and low surface resistance.

The application of ITO on float glass substrate is carried out in a vacuumed condition by magnetron sputtering method called Physical Vapour Deposition (PVD) at around 300°C.

BENEFITS AND SPECTRAL PROPERTIES

• Reflective at higher infrared wavelengths. • Low micro roughness. • Good uniformity of optical transmissivity. • Very high abrasion resistance and coating adhesion.

panel displays, smart windows, polymer-based electronics, thin film photovoltaic, and used as the IR reflector for low-e windowpanes in architectural.

Moreover, ITO thin films for glass substrates can be helpful for glass windows to conserve energy. ITO thin film strain gauges can operate at temperatures up to 1400°C and can be used in harsh environments such as gas turbines, jet engines, and rocket engines.
