Blast mitigating glazing can substantially reduce injury from flying glass resulting from direct blast shock waves (over-pressures). When properly designed, framed, and anchored, blast resistant laminates are capable of maintaining the integrity of the building envelope following an explosion and reducing interior damage. Although there are other mechanisms of reducing the number of glass shards that enter a facility this document deals with factory fabricated glazing with at least two pieces of glass or plastic glazing bonded together with a high performance polymer interlayer.
