SentryGlas® interlayers are used in custom laminated glass applications to help architects, designers and manufacturers meet the increasing need for improved security, energy efficiency and safety.

SentryGlas® interlayers are five times stronger and up to 100 times stiffer than standard PVB interlayers and toughened PVB laminates. With this superior strength, SentryGlas® interlayers help create stronger laminated glass for protection from the elements like storms, impacts, threats and flying projectiles. 

In addition to its strength, SentryGlas® retains exceptional clarity providing a superior long lasting product ideal for architectural applications like skywalks, floors, floating stairs, glass canopies and is ideal for frameless glass balustrades, specially designed so that if the glass is damaged and breaks it will stay intact and hold the load imposed preventing glass falling and injuring and causing injury.
