Commercial Fire Rated Glass Doors for Visibility and Fire Protection

LHSH manufactures commercial fire rated glass doors that combine fire compartmentation with clear visibility through corridors, entrances and shared building spaces.

Unlike a conventional solid fire door, a glazed fire door allows occupants, staff and security personnel to see through the opening while maintaining the required fire separation performance when the correct fire-rated glazing, door leaf, frame, seals and hardware are specified as a complete system.

As a glass fire rated door manufacturer in China, LHSH can support project-specific requirements including fire rating, door dimensions, glazing configuration, frame design, finish, hardware and opening direction.

Why Choose Fire Rated Glass Doors Instead of Solid Fire Doors?

A fire rated glass door is especially useful when a project needs both compartmentation and visual communication between spaces.

● Improve visibility through corridors, entrances and controlled-access areas.

● Allow staff to check activity on the opposite side of the door before opening.

● Support safer pedestrian circulation in hospitals, schools and public buildings.

● Introduce natural light into enclosed corridors and interior building zones.

● Maintain a more open architectural appearance compared with fully solid fire doors.

● Support fire compartmentation when the door, frame, glazing and associated components are correctly specified as a tested assembly.

For this reason, commercial fire rated glass doors are commonly selected for areas where both life safety and visibility matter.

Fire Rated Glass Door Configurations Available from LHSH

LHSH provides different glazed fire door configurations according to opening width, traffic conditions and architectural requirements.

Single-Leaf Fire Rated Glass Door

Suitable for standard pedestrian openings such as corridors, offices, classrooms, hotel areas and equipment-room entrances.

● Compact configuration for standard openings
● Available with fire-resistant vision glazing
● Suitable for inward or outward swing requirements
● Hardware can be configured according to the project

Double-Leaf Fire Rated Glass Door

Designed for wider openings and locations with higher pedestrian or equipment traffic.

● Provides greater clear opening width
● Suitable for public buildings and commercial corridors
● Can incorporate fire-rated glazing in one or both leaves
● Panic hardware and door closers can be specified where required

Unequal-Leaf Fire Rated Glass Door

Suitable when a normal daily pedestrian opening is required together with occasional wider access.

● Combines functional access with fire separation

Fully Glazed or Large-Vision Fire Door

For projects requiring increased transparency, LHSH can review large glazed or fully glazed fire door configurations according to the required fire rating and tested system design.

The allowable glazing area should always be confirmed against the required certification and complete door assembly rather than selected purely according to appearance.

● Door Leaf Steel Thickness: approximately 1.0–1.2 mm depending on configuration

● Door Frame Steel Thickness: approximately 1.5–2.0 mm depending on configuration

The final specification should always be confirmed according to the target certification, required fire rating and approved project drawings. LHSH publishes EN, BS and GB-related fire performance configurations across its current fire door range. 

EI30, EI60, EI90 or EI120: Which Fire Rated Glass Door Should You Choose?

The required fire rating should be determined by the building code, fire strategy, consultant specification and door schedule for the project.

EI30 Fire Rated Glass Door

Provides 30 minutes of integrity and insulation performance when specified as an applicable tested system.

Often considered for internal compartment openings where a 30-minute rating is required by the project.

EI60 Fire Rated Glass Door

Provides 60 minutes of fire resistance under the corresponding tested classification.

Commonly specified for commercial corridors, building compartments and protected access routes requiring a higher level of separation.

EI90 Fire Rated Glass Door

Designed for applications requiring 90 minutes of fire resistance.

May be specified in higher-risk building zones or infrastructure projects depending on local requirements.

EI120 Fire Rated Glass Door

Provides a higher level of fire separation where a 120-minute EI classification is required.

Suitable applications depend on the approved fire strategy and certified door configuration.

The highest available rating should not automatically be selected. Buyers should match the door to the actual requirement shown on the approved fire door schedule.

Commercial Fire Rated Glass Door FAQs

Can LHSH manufacture custom fire rated glass doors?

Yes. LHSH supports customized door dimensions, glazing arrangements, RAL colors, frame configurations and hardware preparation according to project requirements.

What fire ratings are available?

LHSH publishes EI30, EI60, EI90 and EI120 configurations across its current glazed fire door product range. Other fire durations should be confirmed according to the required standard and specific doorset configuration. 

Can the glass size be customized?

Yes, but the size of fire-rated glazing cannot be treated as unrestricted customization. The final glass dimensions should comply with the tested or approved configuration for the required fire rating.

What is the difference between fire-rated glass and ordinary safety glass?

Ordinary tempered or laminated safety glass is designed mainly for impact safety and breakage behavior. Fire-rated glass is specifically engineered and tested for defined fire-resistance performance. Ordinary safety glass should not be substituted for certified fire-rated glazing in a rated opening.

Can LHSH supply the door frame and hardware?

Yes. LHSH glazed fire door specifications include steel frames and options for locks, handles, hinges, door closers, panic bars and other project-requested hardware.
