ApexGlass™ Level 3 - Anti-blast Glass

This ASG product is designed to diminish the  effect of blast pressure wave arising from an explosive device. It absorbs much of the blast energy that will ensure and minimize risk of injuries. It controls and reduces  flying glass debris and sharp splinters that often cause injuries from the blast.


ApexGlass™ Level 3 offers maximum protection without compromising structural integrity.
