Insulated Glass combines two or more glass panes that are spaced apart and sealed with a sealant to appear as a single unit. Also called double glazing, IGUs are designed to reduce heat loss and solar heat gain entering the building, while reducing visible light transmittance. Hence they improve the thermal performance, and reduce energy costs. They can be fabricated to meet sound control requirements, seismic requirements, bullet resistance, hurricane and blast resistance requirements, impact resistance and state energy codes. By combining laminated glass products, tinted glass, Low-E coatings, reflective coatings, silk-screened patterns, etc., a wide variety of insulating glass configurations can be made available to meet diverse aesthetic and performance needs.
The visible light transmittance of insulating glazing systems typically ranges between 7% and 80% while the visible light reflectance is in the range of 13-48%.Insulating glazing can reduce noise by about 30dB and further reduction can be achieved by filling of inert gases and using laminated glazing.
Aluminum spacer frame is automatically curved and formed with only one joint and two seals are applied in insulating glass production. This ensures excellent sealing characteristics and long application life-time.The U value is effectively lowered by insulating glazing; it can be further reduced by filling of inert gases.The dew point of CSG insulating glazing systems is below-65C. It assures of no condensation formation under normal applications.
