insulating glass, also called hollow glass, it is made up of two or more panes of glasses, and these lites of glass separated by a sealed air space, the most important advantage of insulated glass is to reduce thermal losses to improve the thermal performance, these key properties enable insulating glass to meet two very different requirements—keeping heat in during winter and keeping heat out during summer. characteristics * fine heat protection; * sound insulation. better effect if combined with laminated glass; * high saftety insulated glass if conbined with tempered or laminated glass; * get much better effect if applied in such circumstances where has distinct temperature differences applications: *commercial and residential building including vella, office, or other buildings; *airport control tower, airplane, hotel *other areas where has noise excluding requirements; availability: *polysulfide and silicone are available to keep the structure; *varied kinds of glasses can be used in the conbination such as toughened, laminated, ceramic glass, expecially low-e glass; *the thickness for the air sealed in the middle can be a6, a9, a12, other thickness are available on request.
