Fire door installation is no longer just a trade skill — it is a critical life-safety responsibility. With tighter certification regimes, increasing inspections, and evolving standards such as EN 1634-1, installers must ensure that every doorset or pre-hung door is fitted exactly as certified. Even the best fire doors can fail if installed incorrectly, potentially putting lives and reputations at risk.
This is where the Doorfit Fire Door Division excels. Combining technical expertise with deep knowledge of compliant doorsets, Doorfit ensures that installers understand not only how to fit doors correctly but also why every step of the process matters.
Understanding Certification and PAS Accreditations
Before a single door is fitted, installers must fully understand the certification behind it. Certification ensures that the door has been tested to withstand fire for a specified duration, and that all components — leaf, frame, ironmongery, seals, and glazing — form part of a tested system.
Publicly Available Specifications (PAS) are increasingly referenced in the fire door industry to guide compliance. Relevant PAS standards include:
• PAS 24 – Security performance requirements for doors and windows; relevant when specifying doorsets that also need to meet security standards.
• PAS 121 – Fire performance and testing of doors; ensures that fire doors are tested and approved according to recognised standards.
• PAS 9980 – Fire risk appraisal of dwellings; provides guidance on identifying risk and maintaining fire doors in residential settings.
By understanding the applicable PAS standards, installers can ensure that the doors they install meet not only the fire-resistance criteria but also broader regulatory and risk management requirements. At Doorfit, each doorset is reviewed against its PAS-relevant criteria before installation begins. Certified and Compatible Ironmongery Ironmongery, including hinges, closers, latches, panic hardware, and intumescent protection — is critical to fire door performance. Mixing hardware from multiple suppliers or substituting untested components can compromise both fire and smoke resistance.
Doorfit’s Fire Door Division ensures all ironmongery is single-sourced and fully certified, forming part of the approved doorset system. This approach guarantees that each doorset performs exactly as tested under EN 1634-1, while also complying with relevant PAS guidance on installation, maintenance, and auditability.
Precision Installation and Workmanship
Even correctly certified doors can fail if tolerances and installation details are overlooked. Frame fixings, door gaps, alignment, and self-closing functionality all influence fire and smoke performance.
With Doorfit, installers follow a methodical, standards-driven approach, ensuring gaps, clearances, and frame positioning match manufacturer guidance. This meticulous attention to detail ensures that doors not only pass inspection but also perform reliably in the event of a fire.
Seals, Glazing, and Ancillary Components
Intumescent and smoke seals, glazing systems, and other ancillary components must be fitted exactly as specified in the test evidence. Improper installation or substitution of these components can compromise the entire doorset.
Doorfit’s technical knowledge ensures that every seal, gasket, and glazing bead is installed in the correct location, fully replicating the tested configuration. Compliance with PAS guidance further supports the integrity and traceability of these installations.
Traceability, Documentation, and Handover
Modern compliance requires installers to provide a clear audit trail. This includes certificates, installation instructions, photographic records, and labelling. Such documentation is increasingly referenced in PAS standards, especially PAS 9980, which stresses the importance of maintaining fire doors as part of a risk management strategy.
Doorfit embeds traceability into every installation. This ensures that clients have full confidence in the compliance, performance, and ongoing maintenance of their fire doorsets.
System-Led Approach to Fire Door Installation
Installing compliant fire doorsets and pre-hung doors requires more than practical skill. It demands technical expertise, regulatory awareness, and an understanding of system performance — including adherence to relevant PAS standards.
By combining practical experience with knowledge of certification, EN 1634-1 testing, and PAS guidance, the Doorfit Fire Door Division helps installers deliver safer, audit-ready, and fully compliant fire door installations. In a regulatory environment that grows stricter every year, a system-led, technically informed approach is the only way to ensure confidence for both installers and end-users.
