Window security bars and egress

Add intrusion security without defeating an opening required for egress or rescue under the applicable code.

VERT / GREEN

Identify whether the window serves egress/bedroom requirements and document actual opening.

JAUNE / YELLOW

A fixed security grille can improve intrusion resistance while creating an egress hazard.

ROUGE / RED

Do not install fixed bars on a required egress opening without verifying requirements and any required release mechanism.

System triage

Basement bedroom window
Verify required egress before any grille, rigid screen or added lock. Opening already difficult
Correct operation before adding a security device. Bars without interior release
Do not compromise required egress; have the solution reviewed. No applicable egress function
Keep access, maintenance and fire safety in final choice.

What the professional checks

The designer/authority confirms whether the opening is required for egress and device conditions; installer coordinates anchorage and operation.
