CFP Carpentry & Fire Prevention recently completed the installation of five new ply flush fire doors as part of an HMO refurbishment project in Southampton.
The work formed part of a wider property refurbishment, with our team responsible for fitting the new doors and associated fire rated ironmongery while ensuring the gaps around each door were set correctly.
Each installation included Grade 13 fire rated hinges, fire rated handles and latches, with the gaps around the door leaves carefully set between 2mm and 4mm.
Five New Ply Flush Fire Doors Installed
A total of five new ply flush doors were installed throughout the HMO property.
Houses in Multiple Occupation can contain several separate bedrooms and communal areas, making correctly fitted doors particularly important as part of the overall fire safety measures within the building.
For this Southampton project, each door was fitted individually to suit the existing opening and frame.
Fire Door Works Included
- Installation of five new ply flush fire doors
- Grade 13 fire rated hinges
- Fire rated handles
- Fire rated latches
- Door gaps adjusted to between 2mm and 4mm
- Adjustment and fitting of doors to the existing openings
- Final checks to the operation and fit of each door
Achieving 2mm–4mm Fire Door Gaps
One of the key parts of the installation was achieving consistent gaps between the doors and their frames.
The photos from the project show our engineers checking these gaps during installation to make sure they were maintained between 2mm and 4mm around the relevant edges of the doors.
Incorrect or excessive gaps can affect the performance of a fire door assembly, which is why this detail forms an important part of both new fire door installation and fire door remedial works.
Grade 13 Fire Rated Hinges
Grade 13 fire rated hinges were fitted to the new doors as part of the installation.
The hinges support the weight of the door leaf and are an important part of the complete fire door assembly. Correct positioning and fixing are essential to make sure the door hangs correctly and maintains consistent gaps around the frame.
Our engineers fitted and checked the hinges individually as each new door was installed.
Fire Rated Handles and Latches
Fire rated handles and latches were also fitted to the new doors.
The latch plays an important role in keeping a fire door in its closed position, while suitable fire rated ironmongery helps maintain the integrity of the overall door assembly.
All ironmongery was installed as part of the new refurbishment works before the doors were checked for operation.
Fire Door Installation for HMOs in Southampton
CFP works with landlords, property developers, managing agents and contractors carrying out HMO refurbishments and fire safety upgrades throughout Southampton and the surrounding areas.
Our team can assist with new fire door installations, fire door surveys and remedial works to existing doors where defects or excessive gaps have been identified.
This Southampton project involved five newly installed doors as part of a larger refurbishment programme, giving the property a consistent set of new doors with suitable fire rated hardware throughout.
