Why Choose 35mm Fire Doors?
Unlike many fire rated doors that are manufactured in 44mm or 54mm thicknesses, 35mm fire doors are designed to fit standard door frames more easily. This can reduce installation costs and minimise disruption when replacing existing internal doors.
- FD30 fire protection for up to 30 minutes
- Suitable for many existing internal frames
- Ideal for retrofit projects and property renovations
- Available in various styles and finishes
- Designed to help slow the spread of flames and smoke
All our fire doors are manufactured using dense cores and fire resistant materials to deliver reliable performance whilst maintaining attractive aesthetics.
Benefits Of 35mm FD30 Fire Doors
Choosing an FD30 fire door can significantly improve safety for occupants and loved ones. In many homes and flats, fire doors are required to protect escape routes and compartmentalise different areas of a property.
The slimmer profile of a 35mm door makes it an affordable option for upgrading older properties where replacing the entire frame may not be practical.
- Enhanced fire safety throughout the property
- Suitable for bedrooms, kitchens and hallways
- Compatible with intumescent strips and smoke seals
- Available in traditional and contemporary style options
- Designed to comply with relevant UK regulations when correctly installed
35mm Vs 44mm Fire Doors
A common question is whether to choose a 35mm or 44mm fire door. Whilst standard fire doors are often manufactured in 44mm thickness, 35mm options provide an excellent alternative where space is limited.
| 35mm Fire Doors | 44mm Fire Doors |
|---|---|
| Designed to retrofit into many standard frames | May require frame upgrades |
| FD30 fire rating | Typically FD30 |
| Ideal for residential properties | Used in both residential and commercial environments |
| Reduced installation disruption | Additional joinery work may be required |

Installation And Fire Safety Requirements
Correct installation is essential to ensure your fire rated doors perform as tested. A complete fire door assembly includes the door leaf, frame, hinges, latches and seals.
To ensure compliance:
- Use certified fire-rated hardware
- Fit a minimum of three fire-rated hinges
- Install correctly sized intumescent strips and seals
- Check certification labels remain in place
- Ensure appropriate gap tolerances are maintained
Fire doors protect escape routes by helping prevent the spread of smoke and flames through a building. Regular inspection and maintenance are essential to maintain performance.
