Nobler Insulated Glass(Insulating Glass or IGU), consists of two or more glass panels, which separated by a spacer and sealed around the edges by butyl glue,sulfur glue or structural sealant. The hollow part between glass panels can be filled with dry air or inert gas(such as Argon).

Nobler Insulated glass is the most effective way to reduce heat transmission through the glass panels. Especially made of LOW-E glass or reflective glass. IGU become the first choice to meet the requirement of energy saving and environment protection.
