Insulated Glass

Insulated Glass, often called double glazing, is a combination of two or more panes of glass spaced apart with a spacer bar and hermetically sealed with a primary and secondary sealant to form a single unit with one or more air spaces in between. IG units improve the thermal performance, thus significantly reducing heating and air-conditioning costs. IG units also reduce interior condensation in cold climates, and increase comfort near windows, thus maximizing the usable interior space.

By combining Low-E coatings, tinted glasses, reflective coatings, silk-screened patterns, laminated glass products and more, a wide variety of insulating glass configurations are available to satisfy a wide range of performance and aesthetic requirements. IG units can be fabricated to meet state energy codes, sound control requirements, seismic requirements, impact resistance, bullet resistance, and hurricane and blast resistance requirements. IG units can be designed to reduce heat loss and solar heat gain entering the building, with a minimal reduction of visible light transmittance.

IGU (Insulated Glass Unit) Features

Optical properties
The visible light transmittance of insulating glazing systems is normally in the range of 7-80% and the visible light reflectance is in the range of 13-48%

Thermal Properties
The U value is effectively lowered by insulating glazing and can be further reduced by filling of inert gases

Acoustical insulation
Insulating glazing can reduce noise by about 30dB and further reduction is obtainable by filling of inert gases and using laminated glazing.

The dew point of CSG insulating glazing systems is below-65C which guarantees no condensation formation under normal applications.

aluminum spacer frame is automatically curved and formed with only one joint and two seals are applied in insulating glass production, which ensures excellent sealing characteristics and long application life-time.
