INSULATED GLASS FOR WINDOWS AND DOORS ,EN 12150.1, European standard.

Insulated Glass for windows and doors 
Insulated Glass is made of two or more pcs of glass sheets and use sealant gumming glass pcs and aluminum spacers which was filled with desiccant together.
Glazed doors and windows are the major approach for communications between indoor and outdoor spaces. Daylight, sight and decoration are the basic functions of glass while energy efficiency and environmental protection are further additional requirements to glazed doors and windows. For a well-closed space, the indoor and outdoor thermal exchange is mainly achieved through glass. The thermal exchange in large volume between indoor and outdoor spaces means that, in summer, unneeded heat is introduced into the rooms while in winter, the valuable indoor heat flows outward, which worsens the indoor living environment and leads to enormous increase in energy consumption by air conditioners and/or heaters. Insulating glass, especially that combined with solar control coated glass and Low-E coated glass, provides a sound solution.

Features of Insulated Glass
Energy Saving: very low U value (<=1.0w/m²k)could be less if filled with inert gas.
Noise reduction: could reduce 30 decibels and diminish 5 decibels more if the IG unit was filled with inner gas.
Dew resistance: below -70^oC, could ensure IG units prevent dew everywhere in the world.
