Internal Fire Doors
Protect your building from fire spread with high-performance internal fire doors designed, installed, and maintained by our qualified specialists.
Why are internal fire doors important?
An internal fire door is one of the most effective components of a passive fire protection strategy. By forming fire-resistant compartments throughout a building, internal fire doors help to slow the spread of flames and smoke, keeping escape routes clear and providing vital time for evacuation.
High-quality internal fire rated doors also support compliance with current UK fire safety legislation such as the Regulatory Reform (Fire Safety) Order 2005. Whether installed in offices, commercial buildings, residential blocks, or specialist environments, fire rated internal doors are critical to achieving a safe and legally compliant building.
Types of internal fire rated doors we supply and install
At Facilities Fire, we supply and install a comprehensive range of internal fire rated doors, all available with certified performance ratings including FD30, FD60, FD90, and FD120.
Our product range includes:
- Timber fire doors – Robust, versatile, and suitable for most commercial and residential buildings.
- Composite fire doors – Durable, modern door sets engineered for high-traffic environments.

Our internal fire doors include high performing features such as fire integrity, thermal insulation, smoke control, and certified hardware such as hinges, closers, locks, and intumescent seals. All door sets are third-party certified and manufactured to strict quality standards for reliable, consistent fire performance.
Our internal fire door installation services
A fire door is only effective when installed correctly. That’s why our qualified and accredited engineers provide a full installation service that ensures every door performs as intended during a fire.
Our installation service includes:
- Full site surveys and precise measurements
- Door set specification based on building layout and fire strategy
- Correct frame installation, sealing, and ironmongery fitting
- Operational checks, gap measurements, and smoke seal verification
- Detailed documentation, including photographic evidence and installation certificates
All our work is carried out in accordance with BS 8214 and BS 476, and follows recognised third-party accreditation schemes such as BM TRADA and Q-Mark. This ensures every installation is compliant, traceable, and properly certified.
Internal fire door maintenance
To remain compliant, your fire rated internal doors must be regularly inspected and maintained. Over time, normal building use can cause defects such as excessive gaps, damaged seals, misaligned frames, loose hinges, or failing door closers, all of which can significantly reduce performance.
We can provide scheduled maintenance, remedial repairs, and detailed fire door inspection reports to help duty holders meet their legal responsibilities. Our engineers will identify any issues early, carry out corrective works, and ensure every internal fire door continues to meet its certified rating.
