The insulating glass is composed of two or more layers of flat glass. Two or more pieces of glass are bonded and sealed with sealing strips and glass strips by using high-strength and high-air-tight composite adhesive around. 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. Various glass originals with different properties can be selected according to the requirements, such as colorless transparent float glass embossed glass, heat-absorbing glass, heat-reflecting glass, wire glass, tempered glass, etc., and the frame (aluminum frame or glass strip, etc.), which are made by cementation, welding or fusion.
The thermal conductivity of glass is 27 times that of air. As long as the insulating glass is sealed, the insulating glass has the best thermal insulation effect.
High-performance insulating glass is different from ordinary insulating glass. In addition to sealing dry air between the two layers of glass, a special metal film with good thermal performance should be coated on the side of the middle air layer of the outer glass. It can cut off the considerable energy emitted from the sun into the room and play a greater heat insulation effect.
