中空玻璃是由二片或二片以上的玻璃,用充有干燥剂的间隔框隔开,周边用弹性密封胶密封制成的一种深加工玻璃。中空玻璃具有隔热、隔音等特点，减少了取暖、制冷、照明的损耗，可有效地改善人们的居住、办公环境，是一种环保节能新材料，在现代建筑中得到了广泛应用。
Insulated glass:
It’s made of two pieces glass or more,use a frame which have drier and silicone cover the edges.
Insulated glass have funcation of heat insulation,sound proof ect. So it’s energy saving.More and more building use this double glazing unit in this world.
特性：
1、中空玻璃具有节能效果，由于玻璃之间所密封的空气或气体具有较低的热传导性，中空玻璃能减少室内外环境的热传输，可节省能量30~50%。
2、隔音，单片玻璃可降低噪音20~22分贝，普通中空玻璃可降低噪音29~31分贝，特种中空玻璃可降低噪音45分贝。因此，使用中空玻璃可有效地将交通噪音降低到居住、办公可接受的环境。
3、夹层玻璃也可以用来制作中空玻璃门窗，普通的中空玻璃一般不具备抗冲击性能，而一面为夹层玻璃的中空玻璃则成了安全玻璃，可以让您的日子过得更安全、更舒适。
4、防结露，中空玻璃的密封胶能够有效地阻挡水汽向中空玻璃间隔层扩散，间隔框内的干燥剂能够吸收扩散到间隔层的水分，从而保持间隔层干燥。即使在冬季室内外温差较大的情况下，间隔层内也不会出现结露和雾化现象。
Features:
1.Energy saving: because the heat exchange of the gas inside of the closed glass,it can reduce the heat transfers inside.it can save energy 30-50%.
2.Sound proof: single layer glass can reduce sound 20-22db, normal insulated glass can reduce sound 29-31db,special insulated glass can reduce sound 45db.So use insulated glass can reduce the sound from traffic effectively.
3.Laminated gass also can made in insuated glass,because normal insulated glass do not have ability of concussion resist,so use laminated glass made insulated glass to made the glass more safety.
4.Dew proof: insulated glass’ silicone can keep out the water diffuse to interval layer effectively, and the drier also can absorb the water in the interval layer.So the interval layer can keep dry, inspite  in winter,there have big difference in tempeture,interval layer would not have dew.
产品应用民用住宅、医院、办公楼、商场、宾馆、图书馆等幕墙、采光天窗及其它需要保温、节能和宁静的场所。
Application: house,hospital.office tower,shopping center, hotel,library ect.
