Insulated glass is made of two or more pieces of glass that effectively supported and separated each other by a sealed yet framed dry air cavity. The cavity is sealed by a hollow aluminum frame (which filled with desiccant) or compound seal string,  while filled with dry air or inert gas into it, then to sealed by butyle, poly-sulfide sealant or structural sealant to keep the whole glass product’s leakproofness. According to the number of hollow cavity insulated glass can be divided into single-layer insulated glass, double-layer insulated glass and multi-layer insulated glass. Single-layer insulated glass is composed of two flat glass and a hollow cavity; Multi -layer insulated glass is composed by two or more hollow cavities. The more the cavity, the better the insulation and sound insulation, the most widely used is a double silver coated single layer insulated glass, double insulated glass and triple layer insulated glass.

The products can be widely used in glass curtain walls,doors and windows of industrial and high-end buildings, the window and door perspective parts of trains,ships,aircrafts and instruments,and the places that require thermal insulation and temperature control and dew control,such as: government project ,office ,hotel ,library home appliance ,cold storage room and other observation doors and Windows, Effective  sound insulation and prevent heat transfer.

Acoustic Insulation of Insulating Glass
The loudness of sound is measured in decibels (dB). The noise of 60 decibels (dB) will make people uncomfortable; the noise of 80 decibels (dB) will irritate people; the noise of 90 decibels (dB) may cause hearing impairment and the noise of 120 decibels (dB) is out of the normal range of the senses. Standard of environmental noise of urban area is shown in Table 2-3.
Table 2-3 GB 3096-93 standard of environmental noise of urban area (in dB)

Zones	Daytime	Night
Special silent zones (sanatorium, villa area, etc.)	50	40
Residential, culture and education zones	55	45
Mixed zones (mixed residential/commercial and industrial zones)	60	50
Industrial concentrated zones and business center zones	65	55
Crossroads and the two sides of roads	70	55

Types of glass and walls	Average acoustic insulation/dB	Types of glass and walls	Average acoustic insulation/dB
Two-layer insulating glass (4+12A+4)①	28	Lateral painted single-layer wall	47-58
(5+6A+5)	25	Double wall with an air layer	51-61
(12+12A+12)	32	Double wall with an air layer and insulating materials	57-62
Three-layer insulating glass (4+12A+4+12A+4)	30-31	Double wall with insulation materials	57-62

4 in ① presents that the glass thickness is 4mm; 12A presents that the spacer layer is a 12mm-thick air layer.
The acoustic insulation of insulating glass is associated with the thickness and the area of the spacer layer, and the greater the thickness and area, the better the acoustic insulation will be. By increasing the thickness and area of the spacer layer, the acoustic insulation of insulating glass will be improved. In addition, the two-layer or multilayer insulating glass composed of the glass and spacer layer of different thickness can effectively improve the acoustic insulation.
Statistics show that a single piece of glass can reduce noise by 20~22dB and two-layer insulating glass by 29~30dB. In order to improve the acoustic insulation of insulating glass, the usually adopted method is to use the glass substrates which are asymmetrical in thickness, fill the spacer layer with dry inert gas or use laminated glass as the substrates to take advantage of the acoustic damping effect of PVB film. By adopting the above method, the acoustic insulation of insulating glass can be up to 45dB.
Dew Prevention of Insulating Glass
The air in insulating glass is dry due to the inside desiccant adsorbing water molecules, and no dew is formed in insulating glass as the temperature decreases, and it can increase the dewpoint of the outer surface. For instance, when the outside wind speed is 5m/s, the indoor temperature 20°C and the relative humidity 60%, dew is formed on 5mm glass when the outdoor temperature is 8 °C, while dew is not formed on 16mm (5+6+5) insulating glass until the outdoor temperature is -2°C under the same conditions, and dew is not formed on 27mm (5+6+5+6+5) three-layer insulating glass until the outdoor temperature is -11°C.
