Over the years, federal governments, private corporations and international non-governmental organizations have been responding to terrorist attacks on their people and their properties by instituting physical security criteria and requirements. One of the first measures that is often implemented is the installation of blast resistant (a.k.a. anti-shatter, fragment retention) film on the exterior windows of […]

The engineers at Stone Security Engineering have more than 50 years of combined experience in protective design projects incorporating blast, ballistics, forced entry, and vehicle ramming resistance requirements.   During these years, we have seen what works – and what does not work – when implementing these specialized design requirements in new and existing buildings. We want to share […]
