SGG Bioclean self-cleaning glass with photocatalytic properties is cleaned thanks to the sun and the rain.SGG Bioclean self-cleaning glass with photocatalytic properties, from Saint-Gobain Glass, is active thanks to the dual action of sun and rain.

SGG Bioclean’s innovative feature is a titanium oxide-based ultra-thin layer which is deposited on the glass during the manufacturing process. This layer reacts with natural elements such as sunshine’s ultraviolet rays and rainwater to let the glass rid itself of accumulated dirt. With SGG Bioclean, sunshine causes the breakdown of organic dirt, while rainwater or washing water eliminates the residues in a uniform fashion. Result: window panes self-clean and stay clean for longer periods of time. Find information about Saint-Gobain Glass.

SGG Bioclean self-cleaning glass can be used on all facades: public or commercial buildings such as airports, schools or office complexes, residential dwellings, and is equally suited for both new build and refurbishment projects. Basically anywhere where the glass is exposed to day light, in a vertical or inclined position. Solar control and acoustic glass, double-glazed units and design glass will also have advantages.

It harnesses the power of UV rays and rain and has a dual-action self-clenaing effect.

How It Works

1 - photcatalytic action
Ulta-violet rays present in daylight trigger the decomposition of organic dirt and cause the surface of the glass to turn hydrophilic.

The phenomenom of photocatalysis can take place in sunny or in cloudy weather.

2 - hydrophilic action
Thanks to this special hydrohilic action, a water film is formed when rain makes contact with the surface of the glass. This film allows the broken-down dirt particles and mineral dirt to be rinsed away.

Water quickly evaporates on the surface and the glass is left clean and dry.

The term 'self-cleaning' means that the process of cleaning the glass is carried out, or at least greatly assisted, by natural elements. 'Self-cleaning' does not mean 'maintenance-free' especially in heavily polluted environments.

(AGC) of Japan has solved problems in lowering the defect-free rate for the production of fifth- and sixth-generation (5G, 6G) glass substrates, and is expected to tap the market with products with higher price competitiveness in 2006 to grab more market share in the 6G substrate businessIn addition, Wang added, the aggressive capacity added by both Corning of the U.S., the world's No. 1 substrate supplier, and AGC, the No. 2, will lead to price drops for glass substrates and will especially benefit TV panel makers such as AU Optronics Corp. (AUO) and Chi Mei Optoelectronics Corp. (CMO) in TaiwanCurrently, Wang pointed out, a 6G substrate is priced at about 27,000 to 30,000 Japanese yen, about 1,000 to 2,000 yen lower than in the third quarter of 2005.
