What can be used instead of safety glazing to protect windows?

Using a substantial bar or similar device provides an effective means of protecting windows by creating a physical barrier that can help prevent breakage and thwart unauthorized entry. This option contributes to the overall security of a building, particularly in areas prone to vandalism or forced entry.

Safety glazing, such as tempered or laminated glass, is often employed to minimize the risk of injury from glass breakage. However, when substituting with physical barriers like robust bars or grilles, the objective remains to enhance safety and security without compromising accessibility or aesthetics unduly.

The other options do not serve as direct or effective replacements for safety glazing. A lightweight mesh might not offer adequate protection or security, while curtains or blinds are primarily used for privacy and light control rather than physical safety. Decorative grates can enhance appearance but may not provide the strength needed to protect against breakage as effectively as substantial bars. Thus, the use of a substantial bar or similar device stands out as the best alternative to ensure both safety and security of windows.
