Ballistic, Blast, Storm Impact and Forced Entry Resistant Systems
Blast protection must be considered in design when a facility is a potential target or when a building is located in the vicinity of a potential target. The blast from an explosion does not discriminate and will expand radially from its point of origin until it encounters a solid structure, such as a wall with windows and doors.
The blast then causes a pressure to be applied to the windows and doors for a period of time (duration). This creates an impulse or an amount of energy that is imparted to the window and/or door. A portion of this energy is absorbed by the window and/or door through the flexing of the glazing material. The remainder of the energy is transferred to the framing system and anchors.
Minimal rotation of the frame is allowed to ensure the glazing is retained. United States Bullet Proofing's engineering professionals perform a complete computer analysis for each blast application. Anchor bolts are analyzed and furnished as part of a system package to ensure design criteria are satisfied during installation.
