In modern interior design and architecture, internal fire doors with glass have become a smart and stylish choice for both residential and commercial properties. These doors offer a powerful combination of fire safety and aesthetic appeal. They allow light to flow through spaces while maintaining essential protection against fire and smoke.
Whether you're renovating a home, upgrading office interiors, or ensuring compliance in public buildings, understanding the functionality and benefits of internal fire doors with glass is vital. This comprehensive guide will walk you through everything you need to know from fire ratings to design options, installation advice, and maintenance tips.
What Are Internal Fire Doors with Glass?
Internal fire doors with glass are doors specifically designed to slow the spread of fire within a building while incorporating glazed panels for visibility and natural light. Unlike standard fire doors, these doors contain specially manufactured fire-rated glass, capable of withstanding high temperatures for a specified period.
This innovative design provides a balance between life-saving functionality and interior appeal. The inclusion of glass panels ensures rooms are well-lit and visually connected, without compromising safety.
Key Benefits of Internal Fire Doors with Glass
1. Enhanced Fire Protection
The core function of any fire door is to delay the spread of fire and smoke. Internal fire doors with glass achieve this by using materials — including reinforced fire-resistant glass — tested to meet strict safety standards. Depending on the model, these doors can offer either 30-minute (FD30) or 60-minute (FD60) protection, giving occupants critical time to escape during emergencies.
2. Improved Light Flow and Visibility
Unlike traditional solid fire doors, glazed versions allow natural light to pass through rooms and corridors. This reduces the need for artificial lighting during the day and enhances the feel of openness in homes or offices. Glass panels also improve visibility, making them a preferred option in environments where supervision or observation is necessary.
3. Modern Design Aesthetics
Internal fire doors with glass are available in a wide range of designs, finishes, and glazing options. Whether you prefer a minimalist look with clear panels or something more private with frosted or tinted glass, there are many styles to suit your taste. The inclusion of glass doesn't detract from the door's fire-resistant properties — it simply elevates its visual impact.
4. Increased Property Value
Modern, stylish, and compliant fire doors can add value to a property. Homebuyers and tenants appreciate safety features that don’t compromise on aesthetics. In commercial buildings, such doors contribute to a more professional and welcoming atmosphere while meeting regulatory standards.
Understanding Fire Ratings
Fire doors are classified based on how long they can withstand fire. The two most common types for internal fire doors with glass are:
-
FD30 – Offers 30 minutes of protection.
-
FD60 – Offers 60 minutes of protection.
Choosing the right rating depends on the building's layout and usage. FD30 is typically sufficient for homes and small offices, while FD60 is recommended for larger buildings or areas with higher fire risks.
Where Can Internal Fire Doors with Glass Be Used?
Residential Properties
In homes, internal fire doors with glass are often installed between kitchens and hallways or between living spaces and stairwells. These doors provide fire containment while maintaining the light and flow within the home. They’re particularly beneficial in multi-storey homes, flats, or shared properties where safety regulations may apply.
Offices and Commercial Spaces
Glazed fire doors are excellent choices for offices, corridors, meeting rooms, and communal areas. They allow managers to maintain visibility across rooms while fulfilling fire safety requirements. Their clean, modern look also contributes to a well-organized and contemporary work environment.
Public and Educational Buildings
In schools, hospitals, hotels, and other public spaces, internal fire doors with glass provide safety without creating a closed-off or institutional feel. They help maintain clear lines of sight and contribute to accessible and inclusive design practices.
Glazing Options and Frame Materials
The type of glass used in these doors must be certified fire-rated glass, designed to withstand intense heat for the duration specified by the door's fire rating. There are several glazing options available:
-
Clear fire glass – For visibility and maximum light.
-
Frosted or sandblasted glass – Provides privacy while still allowing light to pass through.
- Wired glass – Contains embedded wire mesh for extra strength and heat resistance.
-
Tinted or patterned glass – Adds a decorative touch while maintaining fire resistance.
Frames are typically made from hardwood or steel. Timber frames are ideal for homes and offices, offering warmth and character, while steel frames are more suited for industrial or high-traffic environments.
Regulations for Internal Fire Doors with Glass
When installing internal fire doors with glass, it’s essential to ensure they meet UK fire safety regulations:
-
Must be manufactured and tested according to British Standards (BS 476 Part 22 or BS EN 1634-1).
-
The glass used must also be certified fire-resistant for the door’s rating.
-
Doors must include approved intumescent seals, which expand when exposed to heat, sealing gaps around the door.
-
Self-closing mechanisms may be required, especially in commercial or multi-occupancy buildings.
-
Fire doors should be correctly labelled and installed by a qualified professional.
Compliance isn’t just a legal requirement — it’s rucial for ensuring the doors perform their intended life-saving function.
Installation Guidelines
To ensure effectiveness, internal fire doors with glass must be installed with precision:
-
Always use fire-rated hardware, including hinges, handles, and closers.
-
Frames and seals must be correctly aligned.
-
Avoid DIY installation unless you are trained; improper fitting can void certification.
- Use accredited installers to guarantee compliance.
Maintenance and Inspections
Like any fire safety feature, glazed fire doors require routine checks:
-
Inspect the door leaf and frame for visible damage or wear.
-
Test the self-closing mechanism to ensure it operates smoothly.
-
Check that intumescent strips are intact and not painted over.

Inspect the glazing for cracks or compromise in the seal.
