Glass railing systems are used in a variety of residential and commercial settings for safety and the beauty glass adds to a structure. Laminated glass offers a variety of design options: the interlayer can be clear, tinted, or custom printed. The glass can be flat or curved, fully supported or minimally supported with bolts or clamps. Laminated glass offers a significant benefit over monolithic glass used in railings; namely, if breakage occurs, glass particles will adhere to the laminate interlayer increasing the likelihood of glass retention in the system.
