Primed White FD30 Fire Rated Softwood Door Lining with Loose Stop 2100 x 120 x 32mm
What this product is and who needs it
A door lining is the frame that sits within your wall opening and supports the door leaf. This FD30-rated version is specifically engineered to work with fire-rated doors, providing the structural and safety framework required by building regulations in areas such as escape routes, communal spaces, and fire-separation walls. The loose stop (the vertical piece that the door closes against) is supplied separately, giving you control over final positioning during installation. The pre-primed white finish reduces on-site preparation time and provides a professional base for decoration.
- FD30 fire rating means the frame is tested and certified for 30-minute fire resistance
- Routered channels accommodate intumescent strips that expand when exposed to heat
- Loose stop allows adjustment for door swing direction and final alignment
- Pre-primed white finish reduces need for additional sealing before decoration
Sizing and compatibility
This lining measures 2100mm in height, 120mm in width, and 32mm in depth. The 2100mm height is standard for most UK domestic and commercial doorways. The 120mm width is designed to fit standard partition walls (typically 100mm blockwork plus plasterboard on both sides). The 32mm depth accommodates the door leaf thickness and intumescent strip installation. Confirm your wall thickness and door leaf specification before ordering to ensure proper fit.
- Height: 2100mm suits standard UK door openings
- Width: 120mm fits typical stud and block partition walls
- Depth: 32mm accommodates standard door leaves and intumescent strips
- Check your wall opening dimensions and door leaf thickness before purchase
Pack contents and pre-installation checks
This product comprises the three main lining components (two vertical jambs and one horizontal head) plus the loose stop supplied separately. All pieces are primed white and routered ready for intumescent strips. Before installation, inspect all components for damage, check that your wall opening is square and plumb, and verify that you have the correct intumescent strips for your specific fire-rated door. Ensure the opening is prepared to the correct size and that any old frames have been fully removed.

Installation and fixing considerations
This lining should be fixed into the wall opening using appropriate fixings for your wall type (screws for timber frames, plugs and screws for masonry, or adhesive for block). The loose stop must be positioned and fixed after the main frame is installed and checked for square and plumb. Intumescent strips must be fitted into the routered channels before the door leaf is hung. Ensure all fixings are concealed and the frame is fully supported around the perimeter. Allow adequate time for any adhesive or filler to cure before hanging the door.
- Use fixings appropriate to your wall construction (timber, masonry, or block)
- Install main frame first, then position and fix the loose stop
- Fit intumescent strips into routered channels before hanging the door
- Check frame is square and plumb before final fixing
- Allow adhesive and filler to cure fully before hanging the door leaf
