Curved
Ceilings
Soft undulating shapes, curves,
dramatic bulkheads - all design
possibilities with Luxalon® Curved
ceilings from Hunter Douglas.
Explore your creativity and breakboundaries - inside the curve.

CurvedSoft, Skyward Sculptured

FLEXIBLE BY DESIGN
Luxalon® Curved ceilings from Hunter Douglas add a twist
to the traditional. Imagine concave, convex, and undulating
forms that tempt a look upwards.
Create soft curves and sculpted shapes with Luxalon®
Curved ceilings. 300C (300 mm wide) and 84R (84 mmwide) panels can curve up to 90 degrees, perfect for
opening up public spaces. The Luxalon® curved carriersystem helps to transform standard flat panels into
dynamic ceiling designs.
The curve doesn’t need to stop at the ceiling. Luxalon®
Curved ceilings can partially - or completely - clad
surrounding walls. Over 20 colours and finishes will ensure
you create the perfect look for your project.

LONG LASTING, LOW MAINTENANCE
Luxalon® Curved ceilings are manufactured from rollformed aluminium coil. Finished with a polyester paint,
these ceilings are durable and low maintenance. The
coating is stove enamelled in a continuous coil coatingprocess, which ensures uniform coating thickness andabsolute adhesion.
For exterior applications, please request aluminium panelswith our exclusive Luxacote ® finish.
ALL-ACCESS PLENUM
Most Luxalon® ceiling panels allow full plenum access,and can be easily demounted by hand.

Luxalon® Curved ceilings give you freedom in design.
Our ceiling systems are versatile, and create a varietyof visual effects including unique radial and diagonal
patterns and flowing curves.

CONTENTPERFECTLY PERFORATED ACOUSTICS
Improve the acoustics in a space with ceiling panel
perforations Ø1.5 or 2 mm. Luxalon® perforated panels comewith a special sound-absorbing non-woven tissue glued into
the panel, further enhancing acoustical performance.

PROVEN FIRE PROTECTION
All Luxalon® metal suspended ceilings are fully tested forreaction to fire in official fire tests at Efectis, Rijswijk - anindependent Dutch fire research institute. The ceilings areclassified A2,s1,d0 according to EN 13501-1, and will therefore
not contribute to possible fires.

PANELS
The 300 mm wide panels (1) are madeto measure and curved with a maximum
standard length (L) of 6000 mm. Easy tofix, to the standard 300C carrier (2), oneside of the panel is hung on the prongsof the carrier and then the other side ispressed in with an upward movement.
The panel carrier, which is black, andmade of 1.0 mm thick galvanised steel
or 0.95 mm thick aluminium, is provided
with prongs that accommodate thepanels. Integrated locking clips on
the carrier can lock the panels, whererequired.
Carriers have a standard length of5000 mm and are connected by the
carrier splice (3). Panels are connectedin length by applying a panel end
connector (4) on cross sections of four
panels (or two panels at the edge), stillallowing easy demounting. A nonius
hanger (5) and fixing pieces (6) areprovided for suspension. Trimming
curved and straight edges is possible see our various edge trimming options
for more information.
MAXIMUM SPANS* Depending on the radius: min. span
for radius is 1000 mm, max. span forradius > 50 meters.

The 84R ceiling system consists ofround-edged panels (1) which can beeasily clipped on a carrier (2). The panels
can be joined with the panel splice orby clipping the panels over each other.
Curved 84R ceilings can be created byusing a flexible carrier or curving thepanels (1).

PRINCIPLE
Consider a different and dramatic design- a curved ceiling with straight panels.
This ceiling is possible when you use
the Multi Panel system and the panel
systems 84B, 84R, 7OU and 300C.
BENEFITS• A standard product and production
process creates an extremely costeffective curved metal ceiling solution.
• Curved carriers support concave,
convex or undulating ceilings,
creating dramatic visual effects whileaccommodating varying heights.
• Long and narrow or Wide panel
ceilings are made to measure up to6000 mm, which allows for swift
installation (especially in larger areas)
and reduces the need for joints to aminimum.
• The same easy panel-on-carriersuspension system as used onstandard ceilings, allowing easytransition to straight ceilings using thesame panel.
