DuPont SentryGlas Interlayers

As you doubtlessly know, laminated windows are made of two or more panes of glass bonded to adhesive interlayers. These interlayers help make windows more impact- and blast-resistant than otherwise, and more soundproofed. DuPont's new additions to its SentryGlas line is available in thinner sheets than previously — yet still pretty strong, judging from DuPont's Web site bragging about SentryGlas in a commercial building in Florida that designed to withstand a Category 4 hurricane. That's not a big hurricane, but hey — it's a hurricane!

According to DuPont, applications for its SentryGlas Plus interlayers include hurricane- and blast-resistant glass; minimally supported facades, skylights and canopies; and balustrades, flooring, stair treads and, for your really fancy atrium-type buildings, pedestrian bridges. And as long as we're being fancy-schmancy, the SentryGlas Expressions line offers digitally printed, full-color imaging for this like the wall or partition at left

Yet another model, SentryGlas Acoustic, can replace "monolithic" (their word) noise-reduction glass with slimmed-down interlayers that DuPont claims reduces mid-frequency noise "by about one half."

It all seems worth mentioning to your architect or engineer if you're planning a window-replacement program, or maybe just replacing some doors or redoing the lobby. Whatever the case, the SentryGlas interlayers may might save you a pane in the glass.
