Emergency Atrium Glazing Repair: What to Do When Glass Fails
A step-by-step guide for building managers dealing with emergency atrium glazing failures. Covers immediate safety actions, make-safe procedures, temporary weather protection, insurance notification and selecting an emergency contractor.
When Atrium Glazing Becomes an Emergency
Three situations demand an immediate emergency response: overhead glass breakage (risk of fragments falling on people), severe water ingress during storms (risk of damage to interiors and electrical systems), and structural movement or visible distortion of the glazing framework. Each requires evacuation of the area below and an emergency make-safe response.
Glass breakage in an overhead position is the most serious emergency scenario. When a pane of overhead glass cracks or shatters, there is an immediate risk of [glass fragments falling](/atrium-glass-replacement) onto people below. Even laminated glass, which is designed to remain in place when broken, can eventually detach from the framework if not made safe promptly. Any overhead glass breakage requires immediate evacuation of the area below and an emergency make-safe response.
Severe water ingress during heavy rainfall can cause significant damage to building interiors, electrical systems and stock or equipment. While a single drip may not constitute an emergency, a sudden increase in water ingress volume, particularly during a storm, can indicate a major seal failure or drainage blockage that requires urgent attention.
Structural movement or visible distortion of the glazing framework suggests that the system may be under stress beyond its design capacity. This can be caused by thermal expansion in extreme heat, wind loading during storms, or progressive structural failure. Any visible movement or distortion should be treated as a potential emergency until assessed by a specialist.
Immediate Steps: The First 30 Minutes
Evacuate the area directly below the affected glazing immediately and establish a cordon at 1.5 times the height of the glazing in all directions. The actions taken in the first 30 minutes are critical for protecting people and limiting damage.
Use physical barriers and signage to prevent access to the cordoned area, and assign a responsible person to maintain the cordon until the area is made safe.
Document the situation with photographs and notes. Record the location and extent of the damage, the weather conditions, any events that may have caused the failure, and the time of discovery. This information will be needed for insurance claims and for the specialist contractor who will carry out the make-safe and repair.
Notify the building owner or managing agent, the building insurers, and a specialist overhead glazing contractor. The sooner a specialist contractor is engaged, the sooner the area can be made safe and the cordon lifted.
Make-Safe Procedures
A competent emergency glazing contractor should mobilise a make-safe team within 4-24 hours. The make-safe eliminates the risk of glass or debris falling onto people and provides temporary weather protection until permanent repairs can be carried out.
For broken overhead glass, the make-safe typically involves accessing the glazing from above using rope access or MEWPs, removing any loose or unstable glass fragments, and installing a temporary weatherproof covering over the opening. The covering is usually a polycarbonate sheet or heavy-duty tarpaulin secured to the glazing framework with mechanical fixings.
For severe leaks, the make-safe may involve temporary sealing of the most critical failure points using fast-curing sealant or mastic tape, clearing blocked drainage channels to restore water flow, and installing temporary internal water management measures such as drip trays and channelling to direct water away from sensitive areas.
For structural concerns, the make-safe may involve installing temporary propping or bracing to support the glazing framework until a full structural assessment can be carried out. In extreme cases, it may be necessary to remove glass panels to reduce the load on a compromised framework.
