Rocky Made---Dupont SentryGlas Laminated Glass
DuPont™ SentryGlas® ionoplast interlayers help create lighter, safer, more structural glass that can stand up to greater loads and higher threat levels. Taking advantage of the interlayer's extra rigidity and toughness, structural glass systems — from floors and stairs to balcony rails and minimally supported glass canopies — can enjoy new design freedom.
Superior strength, lasting beauty
The SentryGlas® interlayer 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® retains its clarity – even after years of service. Unlike other interlayers, SentryGlas® is much less vulnerable to moisture exposure or yellowing over time.
Limitless possibilities
