Fixing and buying guide
Deanta Windsor Black Prefinished FD30 Fire Door 1981mm x 762mm x 45mm
What you need to know before buying
This is a solid FD30 fire-rated door, meaning it has been independently tested and certified to provide 30 minutes of fire resistance. It is intended for internal use only and must be installed with appropriate fire-rated hardware and frame to maintain its certification. The door arrives prefinished in black, so no painting or staining is required after installation. Check that your opening dimensions can accommodate the stated size of 1981mm height by 762mm width, allowing for the 15mm trim allowance on each edge (30mm total) needed for proper fitting into the frame.
- FD30 fire rating requires certified installation with fire-rated hinges, handles, and frame
- Prefinished black surface is ready to install without decoration
- Trim allowance of 15mm per edge allows adjustment for accurate frame fit
- Third-party certified by Q-Mark for compliance assurance
- FSC-certified timber confirms sustainable sourcing
Sizing and compatibility
The door measures 1981mm in height and 762mm in width with a 45mm thickness, which is standard for fire-rated internal doors. The 15mm trim allowance per edge means you can plane or sand up to 15mm from each side if needed to fit your opening precisely, providing a total adjustment range of 30mm. Ensure your frame is designed to accept a 45mm thick door and that all hinges, handles, locks, and seals are fire-rated components certified for FD30 use. Standard three-panel bevelled-edge doors typically work with conventional internal door frames, but fire-rated installations require fire-rated hardware throughout.
- 1981mm x 762mm x 45mm is a standard internal door size
- Trim allowance of 15mm per edge allows fitting adjustment
- Requires fire-rated hinges, handles, and frame seals for certification
- Compatible with standard internal door furniture if fire-rated
Pre-installation checks
Before installation, inspect the door for any damage in transit and check that the frame opening is square and plumb using a spirit level. Measure the opening height and width to confirm the door with its trim allowance will fit correctly. Verify that you have fire-rated hinges, handles, locks, and intumescent seals ready for installation, as these are essential to maintain the FD30 certification. Ensure the frame itself is fire-rated or suitable for fire-door installation. Do not install this door with standard non-fire-rated hardware, as this will invalidate the fire rating and compromise safety.
- Check door and frame for transit damage before fitting
