The SentryGlas® interlayer from the Trosifol® Structural product familiy is five times stronger and up to 100 times stiffer than conventional laminating materials. With this kind of strength the glass can be a more active structural element in the building envelope, opening up design possibilities that didn’t exist before. Besides its strength, SentryGlas® ionoplast interlayer retains its clarity – even after years of service. Unlike other interlayers, SentryGlas® ionoplast interlayer is much less vulnerable to moisture exposure or yellowing over time.


Initially developed for the high building envelope protection required for hurricane glazing in the United States, the use of SentryGlas® ionoplast interlayer has now expanded considerably as structural engineers have recognized that the performance benefits developed for hurricane applications could also be beneficial for many other aspects of a building, including façades, overhead glazing, balustrades, doors and partitions.
