For glass that's more than glass
 
Originally created for specialty markets such as high-security glazing and hurricane windows, DuPont SentryGlas glass laminating interlayers now are  being specified wherever architects or engineers need a material that can make a difference in glass performance.
 
5 times tougher, up to **0 times stiffer
Stronger and more rigid than conventional lami-nating materials, SentryGlas interlayers help create safety glass that protects against big-ger storms, larger impacts and more powerful blasts. They become an engineered component within the glass, holding more weight, so the glass can serve as a more active structural element in the building envelope, increasing framing system design freedom.
All this, plus SentryGlas improves long-term weather resistance of laminated glass systems. SentryGlas structural interlayer performance helps architects and glazed building system manufacturers meet society's need for greater healthful living, safety and maintenance ease. It helps builders do more with less, creating innovative new spaces, while providing greater protection for occupants.
 
low Deflection,Stronger Glass before and after Breakage
SentryGlas is  up to **0 times stiffer and 5 times stronger than traditional interlayers, helping thiner laminated glass meet specified wind loads or structural requirements. In many applications laminated glass made with SentryGlas acts like an engineered composite, with low mechanical strain  under loads, and outstanding post-breakage resistance to creep and collapse.
 
Bolted and Frameless Glass
Laminated glass made with stiff SentryGlas can tolerate high stress loads. The interlayer becomes a higher performing structural layer in the multilayer composite. This gives architects and framing system engineers greater design freedom, useful in creating innovative new bolted and point-supported systems. Clean, smooth, expansive facades can now be engineered with minimal metal exposure and reduced need for four-sided edge framing.
 
A New Era For Exposed Edge
Gone are the days when laminated safety glass needed to be edge-framed partly to hide potential edge defects after weathering. Compared with many commonly used interlayers, the advanced DuPont polymer used in the SentryGlas interlayer is less susceptible to moisture intrusion or other weathering effects.
 
Butt-Joined Freedom,Too
In testing with widely used glazing sealants, butt-joined panels of laminated glass made
with SentryGlas interlayers show excellent compatibility, remaining free of clouding or
other edge defects after years of weather exposure and inspection. Butt-joined exterior
glazing made with  SentryGlas and installed in buildings around the world continues to
show outstanding reliability and freedom from edge defects.
 
Effortless,Ready Protection
By installing windows, doors, canopies with DuPont SentryGlas,building owners getting
full-time protection against wind-borne debris, the leading cause of window failure and property loss. And unlike owners who rely on shutters, owners who install glass made with Sentry-Glas don't have to be home to deploy their safety system when weather threatens. Their protection is already in place, guarding their investment in accordance with the world's most demanding building codes.(It can help defend against blasts, burglaries and break-ins, too.)
 
More Daylight,Less worry
Because SentryGlas is stiffer and tougher than conventional interlayers, it can withstand greater impacts (stronger winds and larger objects) in materials-saving thin glazing installations. It also can be used in larger panes of storm-protected glazing, increasing the vision area and reducing framing material and installation labor.The extra stiffness of SentryGlas also helps create a flatterglazing surface,with low post-installation warpage,reduced deflection helps the glass withstand greater wind forces ... even when dry-glazed.
