When it comes to fire-rated doors, particularly those rated for 60 minutes and designed for exterior use, it’s important to follow strict specifications to maintain safety and compliance. One common question we receive is:
Can a 60-minute full exterior door include a vision panel?
The Short Answer: Generally, No
Most 60-minute fire-rated exterior doors are not tested or approved with vision panels. The primary reason is environmental exposure. Exterior doors must endure varying weather conditions — rain, humidity, wind, temperature fluctuations — which can introduce moisture into the door structure.
If a vision panel is added, the beading around the glazing becomes a potential weak point, allowing moisture to seep into the door leaf. This not only compromises the fire resistance but can also weaken the structural integrity of the door over time.
Why It Matters
Full exterior fire doors are typically clad and capped in steel for added durability and weather resistance. Adding a vision panel would require cutting into this protective system, essentially voiding the benefits of the steel cladding and capping — and the cost invested in it.
Additionally, it’s important to note that:
A vision panel cannot be retrofitted into a 60-minute exterior fire door after manufacture.
These doors are tested and certified as complete systems, and any modification after production — such as cutting to install a glass panel — will invalidate fire certifications and compromise the door’s performance. If a vision panel is required, it must be built into the door during manufacturing, using an approved and tested configuration.
Are There Exceptions?
Yes — but they’re rare. Some door manufacturers may have specifically tested and certified a 60-minute exterior fire door with a vision panel. If that’s the case, the manufacturer can provide:
- Approved glass types and glazing systems
- Exact dimensions and placement allowed for the vision panel
- Documentation to prove compliance with fire safety standards
What Should You Do?
If you’re considering a vision panel in a 60-minute exterior fire door, the best approach is to:
- Contact the manufacturer directly
- Request documentation showing fire test results with the vision panel included
- Confirm that the door remains compliant with local building and fire codes
Final Thoughts
While the idea of adding a vision panel might be aesthetically or functionally appealing, it’s crucial not to compromise the fire performance or weather resistance of a full exterior fire door. Always consult your door supplier or fire door manufacturer before making any modifications.
