Many security options are available for commercial windows to increase safety and prevent intrusion. Among the most common are:
Window security film, constructed from layers of polyester laminated together with adhesives, ranging in thickness from 4 mm to 15 mm (or thicker), to increase shatter resistance.
Shatter-resistant window glass alternatives such as polycarbonate, plastic, or acrylic.
Window security bars or grilles that provide additional reinforcement in case of a break-in.
