In this paper the use of laminated glass as a method of providing blast mitigation for a transparent facade is explored. While much progress has been made over the years with PVB-based laminates, the ultimate blast capacity is limited by the interlayer tear energy. The use of a new ionplast interlayer for bomb blast applications demonstrates significant improved blast mitigation capacity over PVB laminates. This improved performance is afforded by the greater tear energy of ionplast polymers and an associated opportunity for new attachment and framing designs. The full potential of this laminate may be realised by optimising the supporting framing and glazing attachment system. Examples of increased performance that are up to four times the US GSA level D specification are presented.
