Bomb Blast Mitigation Windows and Resistance

~ Design fundamentals for Bomb Blast Resistant Windows and Curtain Wall ~

The primary cause of glazing damage is the bomb blast shock wave that expands in all directions from the explosive charge. A secondary cause of bomb blast damage is debris. The two main sources of debris are the intentional missiles in the composition of the bomb blast and fragments from the surrounding environment. The blast resistant window system must be able to withstand two specific pressure wave assaults, Peak Pressure and Impulse (positive duration phase). It should also be noted that peak and impulse values are not only affected by the size and type of charge, but also the distance from the bomb blast.

The Company has successfully undertaken bomb Blast resistant window and curtain wall testing for over 10 years for the UK Government, at the Government’s UK test centre. It was only one of four companies worldwide who were able to pass the testing regimes as set out by the USACE to supply to Military Barracks overseas, for the US Military, following testing at the Energetic Materials Research Centre in New Mexico.

McMullen bomb blast resistant windows and curtain wall have been used extensively throughout Northern Ireland in the Nineties, including numerous significant buildings in Belfast City Centre. The Company has also supplied the windows to numerous Embassies around the world, including Kabul, Baghdad and Beirut.
