What is a tempered window?

A tempered window is a window that uses tempered safety glass instead of standard annealed glass. These windows are specifically designed to provide enhanced durability and safety. In many jurisdictions, building codes require tempered windows in specific areas of a home or business, such as windows located near doors, windows in bathrooms near showers or tubs, and windows situated close to the floor. The tempering process ensures that if the window is struck by a heavy object or a person accidentally falls against it, the glass is much less likely to break. If it does break, the entire pane crumbles into small, dull pieces, significantly reducing the risk of deep lacerations. Tempered windows are also highly resistant to thermal stress, making them ideal for areas that experience significant temperature differences between the interior and exterior. While they look identical to standard windows, they are usually marked with a small, permanent 'bug' or etching in the corner to certify their tempered status. Homeowners and business owners choose tempered windows not only for compliance with safety regulations but also for the added strength they provide against wind pressure and minor impacts.
