Abstract: A blast-resistant glazing system comprises a sheet of blast-resistant glazing material, such as laminated glass, and an elongate retaining member. The retaining member has two spaced opposed lips for receiving an edge region of the glazing sheet therebetween. Each one of the lips lies adjacent a respective one of the major surfaces of the sheet. The glazing sheet is provided with a respective outwardly extending projection on each major surface of the sheet. Each projection interlocks with a respective one of the lips so that withdrawal of the edge region of the sheet from between the lips is resisted by engagement between the projections and the lips.
