ACPI Physical Security Assessment Practice Test 2025 – Complete Prep Guide

For windows located within 40 inches of a door lock, the required thickness of the glazing material is critical for enhancing security. The 1/8 inch thickness specified ensures a balance between sufficient visibility and reasonable strength. This thickness is typically adequate to meet minimum building codes while still allowing light into the space.

In contexts such as physical security assessments, maintaining a clear line of sight and visibility can deter criminal activity, while thicker materials, like 1/4 inch or greater, are usually reserved for higher-security applications. Choosing 1/8 inch for this proximity to door hardware does not unnecessarily bulk up the installation while still complying with essential safety standards.

Understanding these specifications is crucial for anyone involved in assessing or designing secure environments, as thinner glazing would not provide the necessary protection from forced entry or breakage, while thicker materials could introduce issues related to weight and compatibility with standard window frames.
