2 SentryGlas Introducing glass that s more than glass DuPont SentryGlas is an engineered interlayer that s 100 times more rigid and 5 times stronger than conventional interlayers. Which means that now you can use glass itself as a structural element. Build broad, weightless canopies. Transparent facades. Invisible balustrades. And who knows what else? It almost makes you rethink, well, everything. 2

3 3 DuPont SentryGlas Interlayer for laminated glass Lighter weight, enhanced durability and increased postbreakage safety SentryGlas was created by DuPont to resist against extreme atmospheric conditions and environmental stresses like hurricanes, yet it provides superior strength and lasting clarity even after years of service. Why SentryGlas technology? Lighter weight: up to 40% compared to traditional laminated glass. Equivalent and higher strength when compared to monolithic glass Higher durability: open edges application possible and optimal sealant compatibility Enhanced post-breakage behavior: the glass fragment are kept together by the interlayer and the structure will stay in place thanks to SentryGlas intrinsic stiffness. Keeps mechanical properties from low to high temperatures Enhanced transparency
