Security Glass - Blast Resistant

Blast resistant glass laminates can substantially reduce or prevent injuries caused by explosive devices.

As the threat of terrorist attacks with explosive devices increases we have become much more aware of the need to secure buildings against blast. Windows have become a particular focus, as we have learned that many of the injuries sustained in a blast are the result of flying glass. Standard window designs of monolithic glass will shatter in a blast situation, propelling thousands of razor sharp fragments into the occupied space, resulting in serious injury or even death. These injuries can be minimized or even prevented with the use of laminated glass products for blast mitigation.


Laminated products substantially reduce injuries because the glass fragments are adhered to the interlayer material preventing them from being propelled into the occupied space. Laminated products can also increase protection from other flying debris such as rocks, because the elastic interlayer material helps prevent objects from penetrating. Other
materials such as polycarbonates or other plastics can be incorporated into the laminate for additional impact resistance. See below for some of the blast laminates that Dlubak offers.
