There is no specific service life for tempered laminated glass, and generally it can be used for more than ten years. Experts suggest that tempered glass that has been in use for more than 5 years can be coated with a layer of explosion-proof film or replaced to avoid accidents.

Hollow laminated glass is a combination product composed of glass substrate, spacer frame (aluminum strip), desiccant (molecular sieve), and sealing material (butyl rubber, polysulfide rubber or structural adhesive). In the composition of insulating glass, glass and aluminum frame are usually very stable, and the lifespan of insulating glass depends on the lifespan of molecular sieves and sealing materials.

Physical tempering is the process of heating and then rapidly cooling glass, which changes the structure between molecules inside the glass. Chemical tempering is used for ion exchange of the molecular structure on the surface of glass at high temperatures. Both methods have permanently altered the microstructure of glass materials. Therefore, unless there is high temperature and strong chemical reaction, the characteristics of tempered steel will not decay or change over time under normal use.   

What are the characteristics of laminated glass? Laminated glass has high safety. Due to the tough and strong adhesion of the adhesive film in the middle layer, it is not easily penetrated after impact damage, and fragments will not fall off, tightly adhering to the adhesive film. Compared with other types of glass, it has the performance of shock resistance, theft prevention, and explosion prevention.   

Energy saving is achieved by reducing solar radiation, preventing energy loss, and saving electricity consumption for air conditioning through the interlayer film. The interlayer film can also provide a buffering effect on the sound wave vibration products, thereby achieving sound insulation. The interlayer film of laminated glass can block 99% of ultraviolet rays and delay the fading of indoor furniture and curtains. Enhance the aesthetic appearance of buildings.
