Stair nosing, landing nosing, threshold strips and scotia: which trim do you need?

Updated

“Stair nose”, “landing nosing”, “threshold strip” and “scotia” all sound similar, but each one solves a different job around a floor. This guide covers the six trims FloorTrim UK sells, where each is actually used, and the UK naming that matches what you’re searching for.

Stair Nose Profile — top of the staircase

This is what finishes the very top of a stair cladding run: it’s designed for the point where the stair cladding meets an existing floor surface, such as laminate, carpet or ceramic flooring. The profile overlaps the adjoining floor covering to create a neat transition between the staircase and that floor.

It’s a 100 mm wide, 1000 mm long profile, 12 mm thick, with a 40 mm nose and a wood-effect CPL surface rated AC4 / Class 32. The standard profile gives 8 mm of clearance for the adjoining floor; where more height is needed, a compatible 4 mm MDF spacer fits underneath and is secured with a suitable adhesive. It’s supplied with one matching riser, included free of charge (décor on one face, white melamine on the reverse). This is what the cost guide calls “Finish A”.

Stair Nose Profile with Groove — landing nosing

Same 100 × 1000 mm profile, but grooved so it connects to FloorTrim’s Narrow and Wide Landing Boards instead of finishing against a floor directly. It sits along the front edge of a stair landing — whether that’s a mid-flight landing or the top of the stairs — and the groove lets the stair nose and landing boards join together for a neat, continuous surface across the landing. This part is often called a landing nosing: it is the landing-edge version of the same profile.

Floor Transition Profile — threshold strip

This is a separate part from the two stair noses above. It’s designed to create a neat finish between adjoining floor surfaces, and is described for doorways, thresholds and other floor transitions — not specifically for stairs. It’s available as a 1200 mm single profile (supplied in a protective tube), a 2420 mm single profile, or a 2420 mm Trade Pack of 30 for larger jobs, in the same six wood-effect décors as the stair cladding range.

When it fits: use it where two floor coverings meet at roughly the same finished height — carpet to laminate, for example, or between two different floor coverings. It’s best suited to floor coverings 8–10 mm thick. If the two floors finish at different heights, you need a reducer profile rather than a threshold strip.

On naming: in the UK, “door bar” is commonly used for this kind of part, but that term is usually associated with metal profiles. Ours is a wood-effect CPL-surfaced profile, not metal — “threshold strip” or “transition strip” is the more accurate description of what you’re buying.

Scotia Beading — the skirting gap cover

Scotia is a concave moulding that covers the expansion gap between your flooring and your skirting boards, giving a clean finish without disturbing the skirting itself. It’s suitable for use with laminate and compatible wood flooring installations.

Each pack contains 10 lengths of 2.4 m (roughly 24 metres total), in a 15.5 × 15.5 mm profile with an MDF core, available in 9 colours including white and a range of oak and wood-effect décors. If you’re not sure which colour will match your floor, a Scotia Colour Chart is available to compare real samples before you order.

Skirting boards

Where scotia sits over an existing skirting board to hide the expansion gap, a skirting board is the wall-base trim itself — running along the bottom of the wall and covering the same kind of expansion gap from above, around laminate, engineered wood and LVT flooring. FloorTrim’s skirting is a wrapped-MDF profile in white, supplied in 2.42 m lengths in packs of 5, in three profile shapes — Ogee (a traditional S-curved profile), Torus (a rounded, more contemporary profile) and Grooved (flat-faced with a single shallow groove). Boards are 113 mm, 120 mm or 130 mm high and all 14 mm thick.

White MDF Architrave

White MDF architrave is used around door and window frames to cover the joint between the frame and the surrounding wall, creating a neat and decorative finished edge.

Our architraves are made from MDF and pre-finished in White 1010 foil, the same finish used across our White Skirting Board range. This makes it easy to create a coordinated look between your skirting boards and door surrounds without the need for painting.

Choose from Grooved or Torus profiles. Both are 70 mm wide × 14 mm thick and are supplied in packs of 8 lengths.
