What Common Window Vulnerabilities are Found During Security Assessments?

by | Jun 4, 2026

During security assessments, experts frequently identify several critical weaknesses in window assemblies that can lead to unauthorized access or injury. Common vulnerabilities include:

  • Lack of Protective Film: Many facilities have ground-floor windows that lack security or anti-shatter film, leaving them high-risk for forced entry and glass fragmentation hazards.
  • Glass Type Issues: The presence of untempered or annealed glass panels, which break more easily and dangerously than treated glass.
  • Structural Weaknesses: Weak or unreinforced aluminum frames and narrow-stile frames that offer minimal resistance to physical force.
  • Accessible Entry Points: Ground-floor windows on rear elevations often receive less attention but represent primary pathways for forced entry. Similarly, glass doors with unprotected sidelights are a major risk, as intruders can break the side glass to reach inside and unlock the door.
  • Hardware and Maintenance Gaps: Assessments often find compromised mullion integrity in multi-panel systems and window panes that lack external protection like bars or anchored edge retention systems.

It is important to note that while solutions like security window film can mitigate these risks by delaying intruders, security film is NOT bullet-resistant and should not be relied upon for ballistic protection.
