22 August 2019 Trosifol™ Business 2 Observation Decks: Safety with Laminated Glass
1. There is an unprecedented rise in widely accessible, high elevation outdoor spaces that provide a venue for the best views in world, including: • Observation decks • Sky Gardens • Restaurants, bars and pools • Balconies • Unique “entertaining” glass structures, including glass floors, bridges, skywalks and sky slides
2. Structural laminated glass, with interlayers like SentryGlas®, have enabled engineers and architects to design these innovative observation decks and glass structures.

22 August 2019 Trosifol™ Business 29 What makes the SentryGlas® Ionoplast interlayer so special?
Stiffness Durability Post-breakage performance
100x not as moisture sensitive more likely to remain in stiffer than PVB as other interlayers place after breakage than more flexible interlayers Strength Impact resistance
5x more tear proven in hurricane resistant than PVB and tornado areas, as well Design optimization as other types of attacks
Clarity can lead to thinner, lighter laminated glass clearest interlayer constructions of all interlayers Ideal with low iron glass
