Exploring Glass, Frames, and Lock Options for Modern Fire Safety.
Fire-safety is paramount in any construction or renovation project. As architects and builders look for both functionality and aesthetic appeal, one of the most common questions we hear is: “Can fire rated doors have windows?” This blog post will explore everything from glass fire doors and lock mechanisms to frame thicknesses and door certifications (such as MB-78EI Doors from EI30 to EI90). For an overview of available options, check out our Aluminium Fire Rated Doors page.1. Can Fire Rated Doors Have Windows?
The Short Answer
Can fire rated doors have windows, yes they can have windows. However, the glazing must be specially designed and certified to meet fire safety standards. This means the type of glass and the way it’s installed in the door must be tested to maintain the required fire resistance rating.
Why Add Windows to Fire Doors?
- Visibility & Light: Windows allow light to flow between rooms and let occupants see what’s happening on the other side – important for both aesthetic and safety reasons.
- Aesthetics: Glass panes can contribute to a modern, sleek design, especially in commercial or public buildings.
- Compliance: If specified correctly, fire-rated windows can comply with regulations while providing the desired function and look.
2. Can Glass Doors Have Locks?
Absolutely. Glass fire doors can be fitted with locks as long as the locking mechanism itself is certified for fire door use. Some points to consider:
- Fire Door Hardware Certification: Ensure your chosen locks, handles, and other hardware components come with the necessary fire rating.
- Emergency Egress: In buildings where emergency exits are crucial, regulations often require panic bars or other quick release mechanisms that allow occupants to exit swiftly.
- Security Requirements: Commercial properties may opt for mortise locks or electronic access systems. As long as they are tested and approved for fire doors, they are viable options.
3. Is a Full Glass Door Possible?

These doors:
4. Frame Thickness & Materials
Aluminium Frames
One of the most popular options for modern fire rated doors is aluminium, thanks to its high strength to weight ratio, corrosion resistance, and design versatility. Frame thickness typically depends on the required fire rating and the chosen glazing system. Thicker frames generally allow for:
- Better Thermal Insulation
- Higher Structural Stability under extreme heat
- Compatibility with thicker, multi-layer glass
Importance of the Thermal Break
A thermal break in the frame helps control heat transfer, ensuring fire doors also offer excellent thermal performance. This feature is particularly beneficial in commercial and residential buildings aiming to optimise energy efficiency alongside fire safety.
