Blast Hazard Mitigation

As extreme pressures released by an explosive mass impinge on a building’s exterior walls, the elements of the window or curtainwall assembly work together, to withstand the blast load and dissipate its energy. Instead of the historical design practice of specifying thick windows with rigid frames, modern blast-mitigating assemblies are intended to be flexible, and absorb, rather than resist, blast energy.

With more than ten years’ experience in blast hazard mitigation, Wausau’s expertise can be leveraged on your project,  whether for standard operable windows, fixed window wall or curtainwall, or systems custom-designed to your unique requirements.
