Blast Mitigation and Resistance

~ The Basics of Blast Mitigation ~

The primary cause of glazing damage is the shock wave that expands in all directions from the explosive charge. A secondary cause of damage is debris. The two main sources of debris are the intentional missiles in the composition of the weapon and fragments from the surrounding environment. To resist these damaging effects, the 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 explosion.

McMullen Group Holdings Ltd 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.

The windows and Curtain walling 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.
