CFP Carpentry & Fire Prevention recently completed remedial works to two double fire door sets at a site in Maidenhead after defects were identified during a Fire Risk Assessment (FRA).
Both door sets had been fitted without suitable intumescent smoke seals where the two door leaves meet, leaving the meeting stiles without the required seal protection.
Rather than replacing otherwise serviceable door sets, our team carried out targeted fire door remedial works and installed new 15mm x 4mm twin-fin intumescent smoke seals to the meeting edges of the doors.
Missing Intumescent Smoke Seals Identified During the FRA
Double fire door sets require careful attention around the point where the two door leaves meet.
At this Maidenhead property, the FRA identified that there were no intumescent smoke seals fitted between the meeting door leaves on two separate double door sets.
The existing doors could be retained, so the appropriate solution was to modify the meeting edges and install suitable seals.
This type of work forms part of the fire door remedial services carried out by CFP following inspections and Fire Risk Assessments.
Installing 15mm x 4mm Twin-Fin Fire and Smoke Seals
The door leaves were removed and carefully worked on to create the correct recess for the new seals.
We then installed 15mm x 4mm twin-fin intumescent smoke seals along the meeting edges of the doors.
The twin-fin design provides both:
- Intumescent protection, designed to expand when exposed to heat
- Smoke control, using the brush fins to help restrict the passage of smoke around the door leaves
Particular care was taken to achieve a neat, continuous installation along the meeting stiles while retaining the operation and alignment of the double doors.
Remedial Works Completed to Two Double Door Sets
The works included:
- Inspection of the two existing double fire door sets
- Confirmation of the missing seals identified by the FRA
- Removal of the relevant door leaves for remedial work
- Routing the meeting edges to accept the new seals
- Installation of 15mm x 4mm twin-fin intumescent smoke seals
- Refitting and alignment of the door leaves
- Checking the operation of each double door set after completion
The photographs from the project show the doors removed for machining as well as the completed seals running along the meeting edges of the door leaves.
Why Are Intumescent Smoke Seals Important on Double Fire Doors?
A fire door should be considered as a complete assembly rather than simply a door leaf.
The effectiveness of the installation depends on components including the frame, hinges, closers, gaps and intumescent and smoke seals all working together.
On a pair of fire doors, the meeting point between the two leaves is particularly important. If the specification requires fire and smoke seals at this location but they are missing, this can result in the door set being highlighted for remedial work during an FRA or fire door inspection.
Where the existing doors remain suitable, correctly installed remedial components can often resolve the defect without the cost and disruption of replacing the complete door set.
Fire Door Remedial Works Following an FRA
CFP regularly carries out fire door repairs and remedial works following Fire Risk Assessments and fire door inspections.
Depending on the defects identified, works can include replacement or installation of:
- Intumescent and smoke seals
- Fire-rated hinges
- Door closers
- Drop-down seals
- Fire-rated ironmongery
- Door-frame and gap adjustments
- Damaged components
Where a door is beyond suitable repair, we can also provide complete fire door installation and replacement door sets.
Fire Door Repairs in Maidenhead and the Surrounding Area
This Maidenhead project is a good example of how targeted fire door remedial works can resolve defects identified by an FRA while retaining the existing doors wherever appropriate.
If your property has had a Fire Risk Assessment or fire door inspection and issues have been identified with missing smoke seals, excessive gaps, hinges, closers or other fire door components, CFP can assess and carry out the required remedial works.
