There are many factors affecting the sealing performance of hollow glass. For example, the thickness of the sealant, the permeability, and the temperature difference between the inside and outside of the glass are all important. Therefore, in a sealed insulating glass has the best heat insulation effect. The quality of hollow glass can be controlled by the choice of materials and the processing of the glass.

Hollow glass is mainly used in buildings requiring air conditioning. It is also used in the Windows of trains, ships and cars. This is an energy-efficient and environmentally friendly solution. It can be used in buildings that need to prevent noise and has good sound insulation performance. This type of glass is usually made of a high-strength composite adhesive and a seal.

The air and water molecules in hollow glass affect the convective transfer performance of insulating glass. In addition, the temperature difference between the inside and outside of the glass also affects the energy transfer performance of insulating glass. Therefore, the sealing performance of insulating glass is an important factor to improve insulating performance of insulating glass. The thermal conductivity of insulating glass can be improved by sealing insulating glass with butyl rubber or polysulfide glue.

In addition to the sealed hollow glass, inside insulation unit coated low-e coatings is also very important. Low-E coating improves the insulation performance of IGUs. It also protect insulation low-e coating on the unit. In addition, it provides insulation at lower temperatures than designed. It also increases the service life of insulating glass. The coatings come in a variety of colors, including white, translucent, clear, and opaque. The UV resistance of silicone rubber is higher than that of polysulfide rubber. However, silicone rubber is not a good preservative for wood and is very resistant to water vapor.
In order to improve the sealing performance of hollow glass, the rubber sealing insulating glass adopts the three-step sealing operation procedure. First, the aluminum type double sealed insulating glass is sealed with butyl rubber. The outer surface of the glass is then treated with screen or digital printing. After a complete coverage of the inner surface of the glass with opaque glass ceramic materials processing. Finally, press the glass with a high roller. This method can reduce gas convection. In addition, it can prevent lateral separation of insulating glass.
