Safety glazing is required by the International Residential Code in a number of locations and is intended to reduce the potential for injury in the event of accidental contact with the glazing.
The two most common types of safety glazing are tempered and laminated. Each pane of safety glazing is required to be permanently labeled. The label typically consists of an etching in the corner of the window indicating if the glass is tempered or laminated.
The State of Minnesota has updated the building code effective January 24, 2015. We are in the process of reviewing our website to make sure everything is up to code, but you should always review the State of MN Building Code before beginning any project.
