Building energy saving, mainly to improve the insulation performance of building envelope. In several major components of building envelope, the poor insulation of curtain wall and doors and Windows is the main factor affecting indoor thermal environment and building energy saving. Therefore, increasing the thermal insulation performance of doors and Windows curtain wall and reducing energy consumption is an important link to improve the indoor thermal environment quality and improve the level of building energy conservation. Energy-saving doors and Windows relative to the application of ordinary doors and Windows, the heat through the glass radiation to the outdoor part is greatly reduced, to achieve the effect of heat preservation and energy saving, this energy saving effect is achieved through the integrity of the whole door and window system, and the sealant material is an indispensable part of the whole system.

The application of silicone sealant in building doors and Windows curtain wall mainly includes three aspects: two sealing of insulating glass, curtain wall structure, weatherproof sealing and waterproof weatherproof sealing of doors and Windows. The quality of silicone sealant not only affects the safety of the whole building doors and Windows curtain wall structure, but also relates to whether the building meets the requirements of energy conservation and environmental protection.

Insulating glass unit has outstanding thermal insulation performance, is an important material to improve the energy-saving level of doors and Windows, has been widely used in architecture in recent years. The dry air inside the insulating glass can make it sound insulation, heat insulation, prevent condensation, reduce cold radiation and enhance the safety of the glass. In the two seals of insulating glass structure, the first seal is to ensure low moisture permeability, and hot melt butyl adhesive is generally used. The role of the second sealant is to ensure the integrity of the glass unit structure, generally choose silicone sealant, if it is used for structural assembly of insulating glass, you must choose silicone structural sealant.
