2. Aluminum is stronger than wood or vinyl. For this reason,
it is still the dominant choice in architectural and
demanding commercial applications. Its strength also
allows framing widths to be minimized, allowing for
larger glass areas in aluminum windows and doors.
aluminium 1. Aluminium is the most abundant
metallic element on earth, second only
to Silicon
2. Within the planet’s crust, aluminium
occurs most often as alum, which is
actually Potassium Aluminium Sulphate
3. The metal is almost always used as
an alloy, even if it’s more than 99%
aluminium
4. Recycling Aluminium takes just 5%
of the energy used to extract fresh
aluminium from ore
5. Aluminum itself is a good thermal
conductor; therefore most aluminum
window manufacturers offer "thermal-
break" products. In these designs, a
structural insulating material is
incorporated between the interior and
exterior aluminum.
Polyamide thermal break strips
Aluminum is the most popular,
affordable and durable
material in use for doors.
Beyond being resistant to
insects and the elements, the
metal is able to handle the
weight of a large piece of
glass and still slide smoothly
for years.

3. 1. Slim frames and maximum glass : Due to the strength of aluminium, less material
is required in the frame to hold the glass. As a result, narrower frame profiles
are possible for designs that have sleeker, slimmer lines for a more streamlined
overall aesthetic. Its strength also allows for the creation of much bigger
windows and doors, which maximises the glass area to open up the best
possible outdoor view, blurring the lines between indoor and outdoor spaces.
2. Robust, durable and easy to maintain : Aluminium is well known for its robust
properties, especially when exposed to the elements. It is unaffected by UV
rays, it will not rot, rust or bend. What’s more is that it is virtually maintenance
free, only requiring regular cleaning to keep it looking as good as new.
Aluminium is a material especially suited for the South African climate as it
handles damp, rain and harsh sunlight exceptionally well. It won’t warp, crack,
discolor, rot or rust. Aluminium is also fireproof, offering added safety.
3. Long-lasting colour and a high-end finish Any high-end range of aluminium
windows and doors should have a sleek powder coat finish, which means that
they never need to be painted as the finish offers excellent longevity. Because
aluminium is light, malleable and easy to work with, it offers high levels of
wind, water and air-tightness for optimum in-house energy efficiency. Another
thing to think about is that some aluminium windows and doors have an
anodised coating, which is a process that is harmful to the environment. Powder
coating is a far better finish in terms of eco-ratings.
4. Energy efficiency Because aluminium is light, malleable and easy to work with,
its doors and windows can offer high levels of wind, water and air-tightness for
optimum in-house energy efficiency, resulting in warmer, less draughty homes
and lower energy bills. Aluminium is also recyclable, which significantly reduces
the overall carbon footprint of any aluminium windows and doors. In fact,
recycling aluminium requires only 5% of the initial energy consumed to create
it.
5. And lastly, Cobus says aluminium windows and doors offer supreme durability
and longevity, which further reduce their already low carbon footprint.

4. Elements of an aluminum window
Frame : It is the element that contains the sash and hold the
window to the wall thanks to the edge brackets. It can also be
called chassis.
Head and Sill: The horizontal profiles of the frame.
Jamb: It is the vertical profile of the frame.
Sash: It is the moveable element of the window. The movement
of the sash it is possible thanks to the metalwork.
Metalwork: They are responsible for turning the sash or to live it
fixed.
The most important are the followings:
Hinges: They allow the rotation of the sash through clamps.
Latch: It is the mechanism which opens and closes the window.
Glazing bead: This part of the window fixes the glazing. It is
pressed, holding the glass against the rebate of the sash.
Glazing: The transparent part is called glazing or glass. It is
responsible for allowing the light and solar radiation to pass
through.
Muntin: If the glazing is divided in portions, these are known as
muntins or panels.
Weather-strip: Elements between the frame and the sash to
prevent air from entering through these joints.
Pivot hinge: This part is in top and bottom hung windows. It is a
hardware which limits its opening.

5. Aluminium-framed windows are increasingly becoming the preferred
option when it comes to home makeovers or remodelling. Window
specialists make windows using aluminium because it is rust and
maintenance free, it also does not bend as easily as plastic and PVC
frames.
Aluminium windows are highly durable and as aluminium is a light
metal, with thinner frames it makes for lighter windows. They also
come in a variety of colours to match themes around various rooms
and with the colouring option, one can have a dual colour coating
where the inside has a different colour than the outside.
The glass itself can come with options such as self-cleaning and solar
glass. Other options in style available are sliding windows, louvre
windows, casement windows, bay windows among others. The
selection in terms of design, style and colour is wide.
Aluminium framed windows clearly offer superior quality and
variety, and most manufacturers will give several years’ warranty
for their product to back that up. In this day and age, aluminium
windows are the way to go. Once fitted, they prove to be durable
and requiring very little maintenance, adding value to the purchase
and making them a worthwhile investment for any homeowner.

6. 3 TRACK SYSTEM WITH MESH Developments in thermal technology
mean that aluminium windows and
doors are among the best-insulated on
the market, owing to thermal breaks.
Whereas uPVC and timber can expand
and contract when the ambient
temperature changes, aluminium is
highly stable – there’s no expansion or
contraction that would make doors
difficult to open or close.
Aluminium has the potential to
outperform uPVC for insulation when it
comes to larger glass areas, because
glass is an excellent insulator and we
have to line uPVC bars with steel,
which does lower thermal
performance,”
