Insulated glass (IG), Hollow Glass is a prefabricated unit made of two or more glass panels with aluminum or stainless steel spacers, filled with desiccant, which is edge-sealed around with compound sealant. Normally,the spacers width is 6mm,9mm,12mm,15mm,18mm etc.
Performance:
Optical performance Visible LT 10%-80% and LR 13%-35% depends on different panels
Thermal feature Insulated glass can reduce U value, especially when filled with inert gas
Sound insulation Can lower the noise, if applied with the laminated panel,80 decibels of traffic noise could be as low as 45 decibels
Anti-dew Desiccant keeps the dryness inside the spacer and resists forming Of dew
Based on the features above, it is widely used in construction, trains, ships, freezers, etc.
