Primed White FD30 Fire Rated Softwood Door Lining with Loose Stop 2100 x 120 x 32mm
Typical applications and where to install
FD30 fire-rated door linings are essential in properties requiring fire compartmentalisation, including residential buildings, care homes, hotels, and commercial premises. Install these linings in internal doorways that form part of a fire escape route or separate different fire compartments. Common locations include stairwell doors, bedroom doors in multi-occupancy buildings, and doors leading from communal areas. The 2100mm height suits standard internal doorways in most residential and commercial buildings. Always check your Building Regulations approval and fire safety strategy before installation, as FD30 rating is mandatory in specific locations depending on building type and occupancy.
- Residential buildings: bedroom and stairwell doors
- Care homes and sheltered housing: compartment separation doors
- Hotels and hostels: guest bedroom and escape route doors
- Commercial buildings: fire compartment and stairwell doors
- Refurbishment projects: upgrading existing non-fire-rated linings
Installation and preparation
Measure your opening carefully before ordering, accounting for plaster thickness and finishes. The lining arrives primed white and ready to install. Position the lining square and plumb within the opening, using shims or packers to maintain alignment. The loose stop allows you to fit it separately after the main lining frame is secured, providing flexibility for different door thicknesses and finishes. Once the lining is fixed, route out the pre-formed channels to the correct depth and width for your chosen intumescent strip specification—this is critical for fire performance. Install the intumescent strip firmly into the routed channel, ensuring no gaps remain. The primed finish provides a base coat; apply two coats of quality interior paint or wood stain for durability and aesthetics.
- Check opening dimensions and plaster depth before ordering
- Install lining square and plumb using shims or packers
- Fit loose stop after main frame is secured in place
- Route channels to intumescent strip manufacturer's specification
- Install intumescent strip with no gaps or voids
- Apply two finish coats of paint or stain over primer
Fire performance and compliance
This lining is specifically manufactured to support FD30 fire-rated door assemblies. The FD30 rating means the door assembly (lining, door leaf, hardware, and intumescent strips) must resist fire for 30 minutes, preventing the passage of flame and limiting smoke leakage. The routed channels are engineered to hold intumescent strips securely; these strips are essential to the fire rating and must be installed correctly. The softwood construction and primed finish do not compromise fire performance when used as part of a complete, tested fire-rated door assembly. Always use this lining with a certified FD30 door leaf and approved intumescent strips, and ensure installation follows the door manufacturer's technical guidance and Building Regulations requirements.
- FD30 rating requires correct installation of intumescent strips
- Use only with certified FD30 door leaves and hardware
- Routed channels must be filled with approved intumescent strips
- Installation must comply with Building Regulations and fire safety standards
- Obtain certification documentation from door and strip manufacturers
Maintenance and on-site handling
Store the lining flat and protected from weather and moisture before installation. Avoid stacking heavy materials on top, which may cause warping. Once installed and finished, maintain the painted surface by keeping it clean and repainting if damage occurs. Inspect intumescent strips periodically to ensure they remain in place and undamaged; any gaps or compression should be addressed immediately as they compromise fire performance. The softwood construction is durable when properly sealed and finished, but avoid prolonged exposure to damp conditions. If the lining is damaged during installation or use, do not attempt to repair it in a way that compromises the fire rating—consult the door manufacturer or a qualified installer.
- Store flat and protected from weather before installation
- Do not stack heavy materials on the lining
- Maintain painted finish and repair damage promptly
- Inspect intumescent strips regularly for damage or compression
- Do not modify or repair the lining in ways that affect fire rating
