Sharp, permanent edge
The aluminium flange holds the plaster line straight and stops corner cracking at the junction.
Aluminium Profiles · NLP-XF5
A ceiling that floats, a line that stays sharp
The XF5 is a plaster-in shadow gap profile. It cuts a crisp, permanent reveal where surfaces meet and offers an optional channel for a hidden line of light.

Why it matters
The junction is where a room is judged
Look at any well-finished interior and your eye lands on the edges: ceiling to wall, panel to plaster, floor to skirting. A plastered butt joint at these points is rarely straight and tends to crack as the building moves. The XF5 replaces that joint with a deliberate groove.
The groove is dark, narrow and perfectly straight, so the two surfaces read as separate planes with air between them. Add a strip of light inside and the same detail becomes soft, shadowless illumination that seems to come from nowhere.
One detail, two jobs
The gap works as architecture when the strip is off and as lighting when it is on. Decide at design stage, or leave the channel empty and light it later.
Planning note
Fix the profile before final plastering and keep the surfaces on both sides flat. The straighter the substrate, the more precise the shadow line looks once painted.
Features
Why designers specify the XF5
Floating ceiling effect
A dark reveal visually detaches the ceiling from the wall, making low rooms feel taller.
Hidden light source
You see the glow, not the fitting.
Finishes flush
Plaster meets the flange with no screws or raw edges on show.
Light now or later
Install the profile during the build and add the LED strip at handover or as a later upgrade.
Pairs with any strip
Warm, neutral or tunable white, sold separately.
Durable aluminium
A rigid extrusion that holds a straight line over long runs.
Clean on site
Lengths cut and align neatly, speeding the finishing trades.
Dark when off. Invisible source when on.
Unlit, the XF5 is a thin black line that sharpens every edge it follows. Lit, a narrow band of warm or neutral light spills along the ceiling or wall from inside the reveal, with no diffuser lip and no hotspot.
Applications
Where it works
Living rooms
A floating ceiling with a quiet perimeter glow for evenings.
Bedrooms
Soft indirect light that avoids glare when lying down.
Hotel lobbies
Crisp wall-ceiling lines for high, formal spaces.
Offices
Neutral reveals framing partitions and reception walls.
Retail stores
Lit reveals that define display walls without extra fixtures.
Restaurants and cafés
Warm perimeter light with no visible source.
Feature walls
Reveals between panels and cladding.
Staircases
A lit line that guides the eye up the flight.
Corridors
A continuous reveal that lengthens a passage.
Showrooms and galleries
Neutral shadow lines that let exhibits carry the colour.
FAQ
Questions we hear on site
It forms a clean recessed groove where two surfaces meet. The groove reads as a dark line separating wall from ceiling, so the ceiling appears to float, and it protects the plaster edge, the part of a conventional corner that cracks first.
During. Fix the profile to the substrate or board first, then finish plaster or jointing compound up to its flange. Once painted, the flange disappears and only the sharp gap remains.
No. On its own the XF5 gives a precise shadow line. The LED channel is optional and can be used from day one or left empty and lit later.
No. The strip and driver are selected separately, so you can choose the colour temperature and brightness for the room.
Warm white (2700K to 3000K) suits bedrooms, living rooms and hospitality. Neutral white suits offices and retail. Keep one temperature across a room so the glow reads as a single line.
The substrate on both sides should be flat and aligned. A shadow line shows every irregularity, so check the boards before the profile is fixed.
Place it in an accessible, ventilated location such as a ceiling void or service panel, with a cable route planned before plastering so nothing needs to be opened up later.
