DuPont SentryGlas ®For glass that’s more than glassOriginally created for specialty markets such as high-security glazing and hurricane windows,DuPont TM SentryGlas ® glass laminating interlayers now are being specified wherever architectsor engineers need a material that can make a difference in glass performance.DuPontSentryGlas ®strength and openedgedurabilityenable framelesssafety glassbalustrades atsports stadiums5 times tougher,up to 100 times stifferStronger and more rigid than conventional laminatingmaterials, SentryGlas ® interlayers helpcreate safety glass that protects against biggerstorms, larger impacts and more powerfulblasts. They be<strong>com</strong>e an engineered <strong>com</strong>ponentwithin the glass, holding more weight, so theglass can serve as a more active structuralelement in the building envelope, increasingframing system design freedom.All this, plus SentryGlas® improves long-termweather resistance of laminated glass systems.SentryGlas ® structural interlayer performancehelps architects and glazed building systemmanufacturers meet society’s need for greaterhealthful living, safety and maintenance ease.It helps builders do more with less, creatinginnovative new spaces, while providing greaterprotection for occupants.
Make glass safer. Build stronger, lighter.SentryGlas ® is up to 100 times stiffer and 5 timesstronger than traditional interlayers, helpingstructural requirements. In many applicationslaminated glass made with SentryGlas ® acts likean engineered <strong>com</strong>posite, with low mechanicalstrain under loads, and outstanding post-breakageresistance to creep and collapse.Bolted and Frameless <strong>Glass</strong>Laminated glass made with stiff SentryGlas ® cantolerate high stress loads. The interlayer be<strong>com</strong>esa higher performing structural layer in themultilayer <strong>com</strong>posite. This gives architects andframing system engineers greater design freedom,useful in creating innovative new bolted andpoint-supported systems. Clean, smooth, expansivefaçades can now be engineered with minimalmetal exposure and reduced need for four-sidededge framing.Gone are the days when laminated safety glassneeded to be edge-framed partly to hide potentialedge defects after weathering. Compared withmany <strong>com</strong>monly used interlayers, the advancedDuPont polymer used in the SentryGlas ® interlayeris less susceptible to moisture intrusion or otherweathering effects.In testing with widely used glazing sealants,butt-joined panels of laminated glass madewith SentryGlas ® interlayers show excellent<strong>com</strong>patibility, remaining free of clouding orother edge defects after years of weatherexposure and inspection. Butt-joined exteriorglazing made with SentryGlas ® and installedin buildings around the world continues toshow outstanding reliability and freedom fromedge defects.By installing windows, doors, canopies,balustrades or curtain wall systems made withDuPont SentryGlas ® , building owners get fulltimeprotection against wind-borne debris, theleading cause of window failure and propertyloss. And unlike owners who rely on shutters,owners who install glass made with Sentry-Glas ® don’t have to be home to deploy theirsafety system when weather threatens. Theirprotection is already in place, guarding theirinvestment in accordance with the world’smost demanding building codes.(It can help defend against blasts, burglariesand break-ins, too.)Because SentryGlas ® is stiffer and tougher thanconventional interlayers, it can withstand greaterimpacts (stronger winds and larger objects) inmaterials-saving thin glazing installations. It alsocan be used in larger panes of storm-protectedglazing, increasing the vision area and reducingframing material and installation labor.The extra stiffness of SentryGlas ® also helpsglass withstand greater wind forces ... even whendry-glazed.
