Laminated glass lifetime

Laminated glass is a composite glass product in which two or more layers of organic polymer interlayer film are sandwiched between glass and processed to make the glass and the intermediate film adhere together for a long time. The laminated glass will be stuck to the film even if the glass is broken, which effectively prevents the occurrence of debris pitting and penetrating fall events, and ensures personal safety.

Laminated glass lifetime

The lifetime of laminated glass depends mainly on the material of the interlayer. Normally, wet laminated glass and EVA laminated glass are mainly used for indoor partitions, and are not suitable for windows or curtain walls. Wet laminated glass and EVA laminated glass will accelerate aging under sunlight, and yellowing will occur after 1-2 years. Degumming bubbles, ice and fog will appear in 2-3 years. In general, wet laminated glass ages much faster than EVA laminated glass. EVA laminated glass can be used indoors for more than 10 years without direct sunlight.

PVB and SGP laminated glass, which is commonly used as a door or window or curtain wall, has much better whether resistance. The typical failure of PVB and SGP laminated glass is the delaminating. Delaminating means that the glass and the interlayer are disengaged, and the safety characteristics of the laminated glass are lost. Regarding the life of PVB and SGP laminated glass, there are currently no relevant standards and specifications in China. At present, domestic glass processing enterprises generally give 5-7 years product warranty period with reference to foreign PVB and SGP supplier,such as Dupont,Kuarary,Trosifol,Saflex brand.

Laminated glass lifetime

In fact, the life of PVB and SGP laminated glass is greatly affected by the thickness of the interlayer layer, the quality of the laminated glass substrate, and the process control of the laminated glass.
