Why Alumineu uses primary aluminium EN AW-6063 T5
Alumineu uses primary EN AW-6063 T5 aluminium for precision-extruded profiles. The alloy supports consistent geometry, surface quality and heat dissipation across batches.

02Why Alumineu’s diffuser keeps its colour and does not yellow over time
UV-stabilised polycarbonate diffusers retain their colour longer and transmit light evenly. Strip temperature and heat dissipation through the aluminium profile also affect ageing.
03Switching to a shadow gap: INVISIA X201 and X202
INVISIA X201 and X202 replace a classic perimeter with decorative tape by an open shadow gap. The models differ in harpoon seating and junction geometry.
04What is a shadow gap in a stretch ceiling
A shadow gap is a narrow, even reveal between the stretch-ceiling membrane and the wall. A dedicated perimeter profile controls its width and line, so no decorative tape is needed.
05Shadow gap vs decorative tape / end cap
A decorative insert conceals the membrane fixing, while a shadow-gap profile leaves an even reveal at the wall. These are different details, selected before the membrane is cut.
06Contour profile – which jobs CONTURA covers
CONTURA creates an illuminated contour along a wall or around a separate ceiling zone. Unlike LIGHTRA, the line follows an edge rather than crossing the ceiling surface.
07Light line in a stretch ceiling
A light line is an illuminated strip within the surface of a stretch ceiling. It consists of an aluminium profile, an LED strip and a diffuser.
08How to choose light-line width (LIGHTRA)
The width of a light line affects its appearance and the space available for the LED strip. The LIGHTRA range includes X015, X030, X030 S and X050.
09Light line vs LED shadow gap – when to use which
LIGHTRA creates a light line in the ceiling surface, while FLOATIA illuminates a shadow gap at the wall. Both use LED strips, but their construction differs.
10LED shadow gap and floating ceiling effect
An LED shadow gap combines a setback between the membrane and wall with perimeter lighting. This visually separates the ceiling from the walls and creates a floating effect.

LIGHTRA series – light lines (harpoon)
LIGHTRA is a range of aluminium profiles for light lines in stretch ceilings with harpoon-fixed PVC membranes. It includes four models: X015, X030, X030 S and X050.
12Choosing a hidden curtain-rail profile
Choose a concealed curtain-rail profile only after defining the niche geometry, number of tracks and membrane fixing system.
13CURTINA vs TISSURE – curtain niche: harpoon vs clip
CURTINA and TISSURE both conceal curtain tracks in a ceiling niche. The main choice is the membrane fixing: harpoon or clip.
14CURTINA series – curtain niche (harpoon)
CURTINA is a range of aluminium profiles for curtain niches with harpoon-fixed PVC membranes. Tracks remain concealed while curtains descend from the ceiling niche.
15TISSURE series – curtain niche (clip)
TISSURE is designed for curtain niches in ceilings with clip-fixed PVC membranes. The range includes Z401 and Z405.
16LUMNOVA series – light lines (clip)
LUMNOVA Z008 creates a light line in a stretch ceiling with clip-fixed membrane. An LED strip and diffuser fit into the aluminium profile.
17STRATOS vs UNITEXA – two levels: harpoon vs clip
STRATOS and UNITEXA join two stretch-ceiling levels but are designed for different membranes and fixing methods.
18STRATOS series – two-level stretch ceilings (harpoon)
STRATOS covers transitions in two-level ceilings with harpoon-fixed PVC membranes. The range includes X701, X702, X703, X704 and X706.
19Magnetic track 48 V in a stretch ceiling
A 48 V magnetic track supports and powers luminaires in the stretch-ceiling plane. Their positions can be changed without rerouting ceiling wiring.
20MAGTRAK vs VOLTIVA – 48 V track: harpoon vs clip
MAGTRAK X508 and VOLTIVA Z501 integrate a luminaire track into a stretch ceiling. The main difference is harpoon versus clip membrane fixing.
21VOLTIVA series – track / magnetic rail (clip)
VOLTIVA Z501 integrates a lighting track into a stretch ceiling with clip-fixed membrane. The profile retains the PVC edges and the luminaire bus.
22AEROOOM vs AERROLL – slot air: harpoon vs clip
AEROOOM and AERROLL create a linear ventilation slot in a stretch ceiling. AEROOOM uses harpoon fixing, AERROLL clip fixing.
23AEROOOM series – slot diffuser (harpoon / air)
AEROOOM creates a linear ventilation slot in a ceiling with harpoon-fixed PVC membrane. Air is supplied or extracted through the slot.
24AERROLL series – slot diffuser (clip / air)
AERROLL creates a linear ventilation slot in a ceiling with clip-fixed membrane. The profile connects the stretch-ceiling system to ductwork.
25Access hatch in a stretch ceiling
An access hatch provides access to services above a stretch ceiling without removing the whole membrane. Service zones determine its location.
26ACCESSA series – access hatch
ACCESSA covers aluminium access hatches for stretch ceilings. K044, K064, K108 and K128 differ in size.
27Room divider on a stretch-ceiling profile
An aluminium-profile divider zones a room with membrane or slats instead of a solid wall. DECORRA is designed for this purpose.
28CONTURA series – contour profile (harpoon)
CONTURA X601 lights the perimeter of a stretch ceiling through the PVC membrane. The LED strip sits on a shelf in the harpoon wall profile.
29LAMPLIX series – light lines (harpoon)
LAMPLIX X930 and X950 create light lines in ceilings with harpoon-fixed PVC membranes. The models differ in lighting-channel geometry.
30Planning a curtain niche in a stretch ceiling
A curtain niche conceals curtain tracks behind the stretch-ceiling surface. Its depth, width and lighting must be planned before the membrane is cut.
31Two-level stretch ceiling – profiles and logic
A two-level stretch ceiling consists of two membrane planes at different heights. A dedicated profile joins the levels and retains both membranes.
32CLASSIX series – classic wall perimeter
CLASSIX creates a classic junction between a stretch ceiling and wall. The range includes X101, X130 and X140 harpoon profiles for PVC membranes.
33DECORRA series – room divider (interior)
DECORRA divides interiors with aluminium slats. The range includes L005, W005, W010 and W015; lighting depends on the selected configuration.
34FLOATIA series – LED shadow gap and floating edge
FLOATIA is a range of profiles for LED-lit shadow gaps around the perimeter of a stretch ceiling. Models X301–X304 differ in mounting and diffuser use.
35What a stretch-ceiling system is – and the aluminium profile’s role
A stretch ceiling consists of a membrane and profiles that hold it around the perimeter and form details such as light lines, curtain niches, shadow gaps and changes of level.
36MAGTRAK series – magnetic track in stretch ceilings
MAGTRAK X508 integrates a magnetic track into a ceiling with harpoon-fixed PVC membrane. Compatible luminaires mount on the bus.
37UNITEXA series – two-level stretch ceilings (clip)
UNITEXA Z701 forms a step in a two-level polyester-fabric ceiling. The clip profile retains the fabric without a harpoon.
38Slot diffuser ventilation in stretch ceilings
A slot diffuser supplies or extracts air through a narrow line in a stretch ceiling. It replaces a visible grille but remains part of the ventilation system.
39Ready welded corners for stretch-ceiling profiles
Ready-welded NX corners join profile sections without on-site corner fitting. The factory junction preserves geometry and shortens installation.
40INVISIA series – shadow gap for stretch ceilings
INVISIA forms a narrow shadow gap between a stretch ceiling and wall or between ceiling planes. The series is designed for harpoon-fixed PVC membranes.
41Harpoon vs clip: two ways to fix the membrane
Harpoon and clip systems hold the membrane in different ways. The choice affects membrane preparation, installation and the possibility of refitting it later.
42Classic wall finish – when there is no visible shadow gap
A classic wall profile joins the stretch ceiling to the wall without a shadow gap. The fixing is concealed by a decorative insert where the selected detail requires one.
