Do you know insulating glass sealing?
Glass accounts for 60% to 70% of the entire door and window area. It loses sealing and hollow effect, which has a great impact on the overall K value of doors and windows. In addition, door and window glass is affected by external factors such as wind pressure and temperature. stable structure.
The tightness of insulating glass depends on the integrity of the structure, and structural stability is the premise to ensure the tightness. The service life of the insulating glass sealant that plays a sealing role determines the service life of the insulating glass.
The insulating glass system adopts double seals. The first sealant prevents the invasion of water vapor, generally using butyl glue; the second sealant maintains the stability of the structure, generally using silicone glue or polysulfide glue. The service life of the sealant determines the service life of the insulating glass, so the sealing process of the insulating glass needs to be strictly controlled.
