Architectural products with solar
control features
HUNTER DOUGLAS offers building designers a range
of products that combine aesthetic appeal and durability,
with solar control features.
LUXALON Sandwich Wall
LUXALON Sandwich Wall systems provide good thermal
and acoustic insulation. Panels are composed of two skins
of pre-coated metal surrounding an insulating core of either
CFC-free polyurethane foam or mineral wool. The surfaces
are either smooth or embossed.
The extremely flat panel surfaces in aluminium or other
metals are available in a great variety of colours and shapes,
in thicknesses of 35 mm, 50 mm, 60 mm, 75 mm and 100

LUXALON Sun Louvre Systems
Solar heat and indoor light can be controlled by installing
shading elements externally. Hunter Douglas manufactures
a variety of shading products including Single
Aerobrise and Double Aerobrise Sun Louvre Systems,
the Aeroscreen System, as well as the Aerofoil Louvre
System.
These systems offer several advantages including the
ability to control and adjust indoor light, eliminate dazzle
and prevent light pollution, prevent mirror reflection, control
indoor temperature and save power, as well as add an
extra dimension to the building.
The Single Aerobrise System can be installed either horizontally
or vertically. The angle of the fin can be locked in
position in increments of 5º, by means of the adjustable
fixing bracket. The Double Aerobrise System can also be
installed, either horizontally or vertically. The angle of the
fin can be locked in increments of 5º, by means of the adjustable
fixing disk.
In the Fixed Aeroscreen System, a fin suspension and
fixing disk control the fin rotation. The angle of the fin can
be locked in increments of 5º. In the Adjustable Aeroscreen
System, an actuator and driving rod control the fin rota-
mm, and in standard widths of 200 mm, 300 mm, 600 mm,
900 mm and 1200 mm. The products can also be offered in
special colours and customised sizes up to 1200 mm in
width. Several joint systems and concealed fixings add to
the architectural possibilities.
The made-to-measure panels can be curved or cranked
either length-wise or width-wise and can be used for both
horizontal and vertical applications. The panels are connected
by means of a ‘secret’ fixing clamp, providing a joint
which has the facility of adjustment and can accommodate
thermal movement.
LUXALON Sandwich Wall has many panel joint details
providing the designer with a number of aesthetic options.
In addition, false joints can be integrated across the width
or the length of a panel, offering even more design possibilities.
Air and water-tightness are ensured through high-performance
concealed gaskets.
LUXAFLEX HELIOSCREEN Intelligent Sun
Control
According to Hunter Douglas, with HELIOSCREEN sun
screening fabrics and systems, it is possible to prevent most
of the solar radiation from entering a building through the
large areas of glass used on the facades of buildings, whilst
the occupants retain a clear view of the exterior. Rooms and
offices still remain bright, yet cool, with enough natural
daylight to make artificial light often unnecessary.
Developed by Helioscreen, which created the first solar
roller blind made from Screenglass fibre-glass fabric in 1963,
these products are widely used in Europe and many parts
of the world. Helioscreen is a member of the Hunter Douglas
Group.
LUXAFLEX HELIOSCREEN fabrics have properties for
controlling light and heat. The glass core of each yarn is a
complex set of spun glass fibres coated with a bulk-dyed
polymer. The woven fabric has good colourfastness and is
tion. The angle of rotation is between 0º and 120º. Two
standard perforation patterns can be incorporated, to satisfy
acoustic applications. Other specially designed panels
are available upon request.
The fin length depends on the wind load, but cannot
be greater than 3800 mm.
The LUXALON Standard Aerofoil Louvre system consists
of six different aluminium-extruded fins, ranging from
200 mm to 450 mm width, in increments of 50 mm. Other
available fin sizes are 100 mm, 150 mm and 500 mm width,
but these do not correspond to the company’s standard
fixing system.
For the standard system, there are two fixing options.
In the non-adjustable system, the fins are installed in a
fixed position with respect to the frame. The angle of the
fins can be locked in increments of 5º, from 0º up to 180º,
and are locked into position while fixing.
In the adjustable motorised system, the angle of the
fins can be set at any angle, from 0º to a maximum of 120º.
Each fin is attached to two axles and aligned with a setscrew.
The driving rod is attached and adjusted. Finally,
the motor is installed to provide the required angle of rotation
for the fins.

flame retardant. Its good dimensional stability means that
it always retains its shape and has a particularly long life
expectancy. With its resistance to humidity, rot and dirt, it is
ideal for use both inside and outside. Owing to the nature
of the fabric, maintenance is minimal.
Their high degree of reflectance and low level of transmittance,
mean that LUXAFLEX HELIOSCREEN fabrics let
in only a small percentage of solar radiation. According to
Hunter Douglas, studies have shown that with LUXAFLEX
HELIOSCREEN fabrics mounted externally, the inside temperature
of a building may be decreased between 5º C to
15º C, which contributes to energy savings.
HELIOSCREEN offers a wide range of colour choices.
All systems are made-to-measure. They can be operated either
manually or electrically, and include options for sun,
wind and rain sensors.
HELIOSCREEN systems find application in exterior
sunscreening (as in vertical, exterior sunscreens and awnings),
interior sunscreening (as in vertical interior roller
blinds, vertical blinds and panel screens which are vertical
sliding panels in Screen), horizontal and sloped glazing (as
in sun roofs), special applications (as in total black-out
screens); and in tension fabric systems.
LUXAFLEX DUETTE Honeycomb Shades
LUXAFLEX DUETTE Honeycomb Shades contribute to
energy efficiency. The honeycomb pleat design traps air
within the shade, which acts as a thermal insulator. The
shades are clean and crisp in appearance, with pleats that
hold their shape and fabrics that do not sag or fray. Cords
run through the centre of the shades, out of sight. The honeycomb
construction gives the shades the strength and durability.
Compact stacking heights provide maximum visibility
when shades are raised. The cordlock design permits
easy operation, with the fabric extending the full width of
the window.

LUXAFLEX HARMONY Cellular Verticals
LUXAFLEX HARMONY Cellular Verticals combine lightweight,
dimensional fabric vanes with ease of operation.
The look is refreshing and modern with clean lines and a
hint of colour.
Vanes are soft and have an elliptical ‘pocket cell’ to accommodate
a light filtering or room darkening insert. When
closed, the ‘pocket cell’ vanes form an insulating layer that
helps boost energy efficiency. RnF
