Fire Rated Glazing

A guide to Choosing the Right Type of Internal Fire Rated Glass Doors and Partitions

Internal fire rated glass doors and glass partitions

When it comes to building safety and design, internal fire-rated glass doors and fire rated glass partitions play a crucial role. They provide both aesthetic appeal and necessary protection against fire hazards. However, choosing the right fire-rated glass doors and partitions for your project involves considering various factors to ensure compliance with Building Safety Regulations while meeting your design aspirations. 

When Are Fire Rated Glass Doors Required in a Residential Build? 

Fire rated glass windows and doors are required where habitable rooms, except from the kitchen require an opening that directly leads to a final exit, or an emergency escape window or door. 

Understanding Fire Ratings

Before delving into the selection process, it’s essential to understand fire ratings. Fire-rated glass doors and partitions are classified based on their ability to withstand fire for a specific duration, typically measured in minutes (e.g., 30, 60, 90 minutes). This rating indicates how long the door or partition can resist fire and smoke, providing a barrier to contain flames. 

Our fire rated glass can reach up to ‘EI 120’ class which is 120 minutes protection from the passage of flames and fumes.  

Factors to Consider: 

Regulatory Compliance 

Ensure that the chosen fire rated glass doors and partitions comply with local building codes and fire safety regulations. Different regions might have specific requirements, so consulting with a professional or regulatory authority is essential. 

Fire Rating Requirements 

Evaluate the fire risk of the building and determine the necessary fire rating for doors and partitions in different areas. For example, high-risk areas like stairwells might require higher fire ratings compared to office spaces. 

Material and Construction 

IQ’s fire-rated glass doors and fire rated glass partitions are engineered to maintain structural integrity during a fire  prevent the spread of flames. 

Aesthetic Appeal 

While prioritising safety, consider the visual appeal of the doors and partitions. Fire-rated glass offers versatility in design, allowing natural light to flow through spaces and enhancing the overall aesthetics. 


Consider the intended purpose of the doors and partitions. Factors such as sound insulation, thermal performance, and accessibility should align with the project requirements. 

Hollycroft Avenue uses two frameless fire doors linking to the living areas in the above image. The slim steel framed fire rated glass doors add an elegant art-deco inspired finish that is in keeping with the traditional style of this London property.  

Totteridge Common (inset above) uses fire rated glazing to the pool basement area of this luxury dwelling. The highest rating of fire retardant glass was used within this project. The composition of the specified fire rated glass doors and walls in this project makes for an excellent noise reduction solution due to the thickness of the glass.  


Paulton Square uses fire rated glass partitions to the entrance of the basement extension.  

Selecting the right fire-rated glass doors and glass partitions involves a balance between safety, aesthetics, and functionality. It’s imperative to collaborate with experienced architects, designers, and contractors to ensure compliance with regulations and project specifications. By considering fire ratings, materials, design preferences, and maintenance requirements, you can make informed decisions that prioritise safety without compromising on style.
