Laminated Glass / PVB vs Kuraray-Sentryglass
SentryGlas® was initially developed for hurricane glass glazing applications in the United States. Made using ionoplast polymer technology, SentryGlas®is chemically different from PVB (like Trosifol and Butacite), making it water resistant, clearer and stronger. With its superior strength to traditionally laminated glass, SentryGlas® set a new standard in strength for lamination and has continued to lead the industry. It has since expanded its use, as structural engineers have recognized that the performance benefits developed for hurricane applications could also be beneficial for many other aspects of a building. This includes facades, overhead glazing, balustrades, doors and partitions. Today, many modern architectural buildings use SentryGlas® to create new, and less framed glass structures.
The SentryGlas® interlayer is five times stronger and up to 100 times stiffer than conventional laminating materials. With this kind of strength, SentryGlas® opening up design possibilities that didn’t exist before.
