Crystal clear safety thanks to DuPont™ SentryGlas®

It also adds anti-intrusion security, sound reduction and protection from UV rays. Two common types of interlayer for laminated glass are films made of polyvinyl butyral, also called PVB, or DuPont™ SentryGlas® ionoplast.
The latter, developed especially for structural elements in architectural glazing, offers greater levels of clarity, is 5 times tougher and up to 100 times stiffer than PVB. Accordingly, SentryGlas® is particularly well-suited to overhead glazing installations, facades, stair treads, balustrades or flooring applications.
The laminates photographed here were made with low-iron glass, gaining popularity for its clear white light, compared to using normal (greenish) glass. In laminates made with low-iron glass, the color contributed by the interlayer becomes more important. Many architects prefer the more natural, non-yellow light transmitted through low-iron laminates made with SentryGlas® interlayers (right) over those made with PVB (left).
