Specifications

What it's used for

• Lining new internal door openings in residential properties where a consistent walnut finish is required without on-site finishing work.
• Replacing damaged or dated door frames in renovation projects, particularly where other walnut joinery is already in place.
• FD30 fire door installations in domestic settings such as kitchen-to-hallway or garage-to-house openings, using the fire-rated version with intumescent seal.
• New-build or conversion projects where a factory finish reduces programme time and removes the need for a decorator to coat frames on site.

Fitting and handling

Allow the lining kit to acclimatise in the room where it will be fitted for at least 48 hours before installation, keeping it flat and away from direct heat sources such as radiators. Fix through the lining into the structural reveal using appropriate timber frame fixings or masonry anchors, depending on your substrate. The removable door stop is best fitted after the door has been hung, which allows you to adjust the stop position for a tight, draught-free close without re-working the frame.

FAQ

What is the difference between the 108mm and 133mm lining kits?

The width refers to the depth of the lining board, which should match the thickness of your finished wall. A 108mm lining suits a standard stud partition or a block wall with standard plaster, while 133mm is used for thicker walls, typically blockwork with dot-and-dab or a timber frame with additional insulation. Measure your reveal carefully before ordering.

Do I need the fire-rated version for an FD30 door?

Yes. Where building regulations require an FD30 fire door, for example between an integral garage and a habitable room, the frame lining must also meet fire performance requirements. The fire-rated version of this kit includes an LP1504 intumescent seal that expands under heat to close any gap between door and frame, maintaining the integrity of the fire barrier.

Can the pre-finished walnut lining be painted or stained on site?

The factory lacquer is applied to provide a ready-to-use walnut finish and is not intended as a base for paint or stain. If you plan to paint your frames, this product is not suitable and you should consider an unfinished white primed or MDF lining instead. The walnut veneer finish is designed to coordinate with pre-finished walnut internal doors from the same Deanta range.
