Insulating glass is made up of two or more layers of flat glass. Two or more pieces of glass are bonded and sealed with sealing strips and glazing strips around the perimeter with a high strength, high gas tightness composite binder. The middle is filled with dry gas and the frame is filled with desiccant to ensure the dryness of the air between the glass sheets.
The glass can be made according to the requir-ements of different properties of the original glass, such as colourless clear float glass embossed glass, heat-absorbing glass, heat-reflective glass, laminated glass, toughened glass, etc. and the frame (aluminium frame or glass bars, etc.) after gluing,welding or fusing can be used.
