What Are Fire Rated Glass Doors?
Fire-rated glazed doors combine safety and style by incorporating transparent, fire-resistant glass into sturdy frames. These doors are designed to:
- Compartmentalize fire and smoke.
- Provide clear visibility for safe evacuation.
- Meet fire-resistance standards for specific durations (e.g., 30, 60, 90 minutes).
- Develop architectural design without compromising safety.

Importance of Fire Rated Glass Door Installation
- Ensures Fire Containment: Correctly installed fire-rated glazed doors create a secure barrier that confines fire and smoke to a specific area. This containment allows occupants to evacuate safely and buys valuable time for emergency responders to control the fire.
- Maintains Structural Integrity: Fire-rated doors are designed to endure high temperatures without warping or breaking. Poor installation, such as improper sealing or alignment, can compromise the structural integrity of the door, rendering it ineffective in an emergency.
- Complies with Safety Regulations: Building codes and fire safety regulations mandate specific installation standards for fire-rated doors. Proper installation confirms compliance with these standards, avoiding legal repercussions and ensuring the safety of the building’s occupants.
- Enhances Long-Term Durability: Fire-rated glazed doors are heavy and subjected to dynamic loads from frequent use. Proper installation, including secure anchoring and precise alignment, minimizes wear and tear, extending the door’s lifespan.
- Prevents Gaps and Weak Points: A poorly installed fire-rated glazed door may leave gaps or weak points that allow smoke and flames to pass through. Ensuring tight seals and correct positioning eliminates such vulnerabilities, maintaining the door’s effectiveness.
Key Factors to Consider During Installation
Wall Compatibility
- Fire rated glass doors should be installed on fire-resistant walls, such as reinforced concrete or load-bearing structures.
- For lightweight walls like plasterboard or aerated concrete, blind frames are essential to maintain structural integrity.
Dilatation Gap
- A 15 mm gap between the doorcase and wall is recommended to accommodate thermal expansion during a fire.
- Fill the gap with fire-resistant mineral wool and seal it with mastics for added protection.
Certified Materials and Hardware
- Ensure that all components, including glass, frames, hinges, and seals, meet the required fire-rating standards.
Common Installation Mistakes and How to Avoid Them
Overlooking Building Codes
- Get flexible with local regulations to avoid penalties and safety risks.
- Collaborate with architects and fire safety experts to ensure compliance.
Inadequate Door Selection
- Choose doors with appropriate fire ratings for the building’s requirements.
- Verify certifications for both doors and hardware.
Poor Installation Techniques
- Work with skilled professionals to ensure proper alignment, sealing, and fastening.
- Avoid leaving gaps that could allow smoke or fire to pass through.
Fire Rated Glass Doors Installation Steps
Installation on Reinforced Concrete Walls
Step 1: Preparation
- Inspect the Wall: Ensure the wall is fire-resistant, stable, and free from cracks or structural damage.
- Verify Measurements: Confirm the dimensions of the door frame and opening to ensure compatibility.
Step 2: Attach the Door Frame
- Position the Frame: Place the door frame into the opening, ensuring it is centered and aligned with the wall.
- Secure Anchors: Drill holes into the concrete wall to accommodate the frame’s anchor points.
- Install Anchors: Use heavy-duty anchor bolts or expansion anchors to secure the frame to the wall. Ensure the frame is firmly attached to prevent movement.
Step 3: Ensure Proper Alignment
- Level the Frame: Use a spirit level to confirm the frame is perfectly vertical and horizontal.
- Adjust as Needed: Make necessary adjustments before tightening the bolts completely.
Step 4: Fill the Dilatation Gap
- Insert Mineral Wool: Place high-density, fire-resistant mineral wool into the 15 mm dilatation gap around the frame. This gap accommodates thermal expansion during a fire.
- Seal with Mastics: Apply fire-resistant mastic over the mineral wool to protect it from environmental factors and enhance the fire seal.
Step 5: Install the Fire Rated Glass
- Position the Glass Panel: Carefully place the fire-rated glass into the frame, ensuring it fits snugly without strain.
- Secure the Glass: Use fire-rated glazing tape or gaskets to hold the glass firmly in place.
- Seal the Joints: Apply a continuous bead of fire-rated sealant around the glass perimeter to eliminate gaps and ensure airtight sealing.
Step 6: Final Inspection
- Check Stability: Verify that the door and glass are securely installed and do not shift or rattle.
- Test Functionality: Ensure the door swings freely, aligns properly with the frame, and latches securely.
Installation on Aerated Concrete Walls
Step 1: Preparation
- Reinforce the Wall: Since aerated concrete walls are less dense, additional structural support is necessary. Prepare to install a blind frame made from hollow structural sections (HSS).
- Verify Measurements: Measure the opening and blind frame dimensions to ensure a proper fit.
Step 2: Install the Blind Frame
- Position the Blind Frame: Place the HSS blind frame into the opening.
- Weld Support Rods: Insert 10 mm diameter steel rods vertically into the wall at intervals of approximately 800 mm. Weld the blind frame to these rods for stability.
- Anchor the Frame: Use appropriate screws, such as Hilti HUS S screws, to fasten the blind frame securely to the wall.
Step 3: Attach the Door Frame to the Blind Frame
- Align the Door Frame: Position the door frame against the blind frame, ensuring proper alignment.
- Secure the Frame: Fasten the door frame to the blind frame using compatible fire-rated screws or bolts.
Step 4: Fill the Dilatation Gap
- Insert Mineral Wool: As with reinforced concrete walls, place high-density, fire-resistant mineral wool into the 15 mm dilatation gap.
- Seal with Mastics: Apply fire-resistant mastic over the mineral wool for added protection.
Step 5: Install the Fire Rated Glass
- Position the Glass Panel: Fit the glass into the frame, ensuring it sits securely without undue force.
- Secure the Glass: Use glazing tape or fire-resistant gaskets to hold the glass in place.
- Seal the Joints: Apply fire-resistant sealant to the edges of the glass, creating a tight, fireproof seal.
Step 6: Final Inspection
- Verify Stability: Check that the blind frame, door frame, and glass are all secure and stable.
- Test Door Functionality: Ensure the door operates smoothly and aligns correctly with the frame.
- Inspect Seals: Confirm that all seals are intact and gaps are filled appropriately.
