Compared with the application of ordinary doors and windows, energy-saving doors and windows have greatly reduced the heat radiated to the outdoors through the glass, achieving the effect of heat preservation and energy saving. This energy saving effect is achieved through the integrity of the entire door and window system, and the sealant material It is an indispensable part of the entire system.

Insulating glass units have outstanding thermal insulation properties and are important materials for improving the energy-saving level of doors and windows. They have been widely used in buildings in recent years. The dry gas inside the hollow glass makes it have the functions of sound insulation, heat insulation, anti-condensation, reduce cold radiation and enhance the safety of the glass. In the two seals of the hollow glass structure, the first seal is to ensure low water vapor penetration, and hot-melt butyl glue is generally used. The role of the second sealant is to ensure the integrity of the glass unit structure. Generally, silicone sealant is used. If it is used for structural assembly of insulating glass, silicone structural sealant must be selected.

1. Long-lasting resistance to environmental factors, especially heat, water or moisture and ultraviolet rays;

3. Low water vapor and gas permeability under operating conditions.
