Deanta Windsor Black Prefinished FD30 Fire Door 2040mm x 826mm x 45mm
What you need to know before buying
This is a FD30 fire door, meaning it provides 30 minutes of fire protection and must be installed in a fire-rated frame with appropriate hinges and hardware to maintain its certification. The door measures 2040mm in height by 826mm in width by 45mm in thickness. It arrives prefinished in black, so no painting or staining is required. Each edge has a 15mm trim allowance (30mm total), which means you can plane or sand up to 15mm from each edge if needed to fit your opening precisely. The door comes with a 10-year manufacturer's guarantee.

Compatibility and installation requirements
To maintain FD30 certification, this door must be installed in a fire-rated frame with fire-rated hinges and hardware. Standard door frames and fittings will not preserve the fire rating. You will need to source a compatible fire-rated frame kit and ensure all hinges, locks, and closing devices are also fire-rated and approved for use with FD30 doors. The door's 45mm thickness is standard for fire doors and will fit frames designed for this specification. Verify your frame and hardware are certified before installation.
- Requires fire-rated door frame (not standard frame)
- Needs fire-rated hinges and hardware
- 45mm thickness is standard for FD30 doors
- Check all components are Q-Mark or equivalent certified
- Consult Building Control if uncertain about compliance
Pre-installation checks and preparation
Before fitting, inspect the door for any damage in transit and check that the frame opening is square and level. Measure your opening carefully; the door is 2040mm x 826mm, and you have up to 15mm trim allowance per edge if adjustment is needed. Do not plane or sand more than the stated trim allowance, as this may compromise the fire rating. Ensure the frame is installed and secured properly before hanging the door. The prefinished black surface requires no further treatment, but protect it during installation to avoid marks or damage.
- Check door and frame for transit damage
- Verify frame opening is square and level
- Do not trim more than 15mm per edge
- Confirm fire-rated frame and hinges are in place
- Protect prefinished surface during handling and installation
- Allow door to acclimatise to room conditions for 24 hours before fitting if possible
