At Supreme Doors, we’re often asked, “Are glass doors fire-rated?” The short answer is – yes, some glass doors are fire-rated, but not all. In this blog post, we’ll explain what makes a glass door fire-rated, where they’re used, and what to look for when choosing one.
What is a fire-rated door?
A fire-rated door is specifically designed to resist the spread of fire and smoke for a set period, typically 30, 60, or 120 minutes. These doors are tested under strict conditions to ensure they meet fire safety standards. They are essential in both commercial and residential settings for creating safe escape routes and compartmentalising buildings in the event of a fire.
Can glass be fire-rated?
Not all glass is created equal. Standard glass will shatter under intense heat, making it unsuitable for fire protection. However, fire-rated glass is specially manufactured to withstand high temperatures and prevent the spread of flames and smoke.
Fire-rated glass is available in several types, including:
-
Wired glass – contains a wire mesh that holds the glass together during a fire.
-
Ceramic glass offers excellent heat resistance and visibility.
-
Glass with intumescent interlayers – these layers expand when exposed to heat, providing an extra barrier against fire.
Are glass doors fire-rated?
Glass doors can be fire-rated if they are constructed using fire-resistant glass and certified framing systems. These doors must meet the same rigorous fire safety standards as traditional fire doors.
Fire-rated glass doors are most commonly used in:
-
Commercial entrances and lobbies
-
Schools, hospitals, and office blocks
-
Escape routes and stairwells
-
Areas requiring both visibility and safety
At Supreme Doors, we supply and install fire-rated doors, including those with glass panels, as part of our wider security and safety solutions.
What to look for in a fire-rated glass door
When choosing a fire-rated glass door, consider the following:
-
Certification: Look for doors tested and certified to UK fire safety standards (e.g. BS 476 or EN 1634).
-
Integrity and insulation ratings: These define how long the door can maintain structural stability and limit heat transfer.
-
Frame compatibility: A fire-rated door must be installed in a certified fire-rated frame for full effectiveness.
-
Maintenance: Regular inspections and servicing are essential to ensure ongoing performance.
