Advantages of Aluminum Windows & Doors

Aluminum is long lasting

Aluminum is highly resistant to weathering and corrosion and has a natural anti-corrosion coating. In addition, oxidation (corrosion) is prevented by anodizing (controlled oxidation). (Anodizing also provides the desired surface appearance.) The life of an aluminum window is shown as 40 years. The surface treatment thicknesses that should be applied to the aluminum window profiles to be used in areas with high corrosion risk should be carefully specified in the specifications.

Aluminum retains its mechanical properties at high and low temperatures

Aluminum windows and doors continue to maintain their mechanical properties at low and high temperatures. This is especially important in applications with high and wide frame intervals. In thermally insulated aluminum profiles, it is recommended to use polyamide thermal insulation plastics containing 25% glass fiber, which are specially designed to be compatible with aluminum in terms of thermal elongation coefficient. In this way, the aluminum frame and the insulating plastic lengthen and shorten together.

Aluminum can be produced in precise dimensions

As aluminum profiles are light and durable, and have a very high application precision, they offer architects customized design possibilities. In other words, aluminum profiles can be produced in very precise dimensions.

Aluminum frames allow wide openings

Since aluminum window frames are durable, they allow the use of frames with less visible width. Narrower frames mean wider lenses. Today’s architecture pushes the limits in this regard and tries to offer wider openings with smaller frames. Aluminum is the most suitable material for this purpose. While limited-size solutions can be produced with wooden and plastic joinery, you can pass wide openings with aluminum windows. Aluminum joinery can be used safely with high moments of inertia in high-rise buildings, where resistance to wind load is very important, in openings through floors such as French balconies, shop windows, wide sliding and folding doors from floor to ceiling. The durability of aluminum, high moments of inertia, allows the manufacture of large-span sliding and casement doors and windows.

Aluminum is easy to maintain

Aluminum has a high chemical resistance by nature. It is extremely easy to clean and maintain compared to wood and vinyl (PVC-u) windows. Vinyl windows need to be wiped with alkaline detergents every 6 months to regain their first-day appearance. Aluminum is cleaned even with rain.

Aluminum is environmentally friendly

It is 100% recyclable, natural and environmentally friendly. Recycling provides 95% energy savings. In other words, the energy spent for recycling is only 5% of the energy spent for primary production. Recycling aluminum scrap saves 80 million tons of greenhouse gas emissions. Lead, mercury etc. It does not contain toxic and carcinogenic substances.

Fire performance of aluminum

Aluminum does not cause toxic gas emission in fire. Aluminum joinery windows comply with fire regulations. There is a requirement to use aluminum joinery in the specifications of the Ministry of Public Works, especially in hospital and school projects. In addition to being resistant to heat, the absence of sparks and toxic gases is an important feature of insulated aluminum windows. PVC-u window can release life-threatening acid salt gases and dioxin gases in case of fire.

PVC is not the equivalent of aluminum.

There are many situations where plastic (PVC) joinery cannot be used instead of aluminum. It is only possible with aluminum material to narrow the facade, window and sliding joinery frames as much as possible and thus to obtain wide glass openings, to realize wide sliding and wing opening joinery, to carry heavy mechanical loads on the frames. In this respect, aluminum is still indispensable for architectural projects. Aluminum joinery is much more durable and stronger than PVC-u joinery, they do not emit dangerous pure acid gases in fire.

Aluminum provides excellent thermal insulation

As you know, aluminum is not a very suitable material for thermal insulation. However, aluminum profiles used in aluminum windows are thermally partitioned. (see: heat-insulated aluminum profiles) Briefly, aluminum profile parts that come into contact with the interior and exterior are separated from each other by plastic thermal insulation barriers, that is, the 2 aluminum parts do not come into contact with each other. Thus, thermal insulation is provided. However, many improvements are made to improve thermal insulation, especially increasing the length of these insulation barriers. (see: improving thermal insulation in aluminum window frames)

With aluminum windows, you can design a window with a window thermal conductivity coefficient (Uw) = 0.8 W/m².K. For examples see: passive house windows.

Rich opening options

There is a wide variety of window styles and window opening options in aluminum joinery. There are accessories suitable for every request to realize these expansion options. Accessory slots where these accessories will be used are designed by aluminum system manufacturers, taking into account the accessory standards.

Aluminum offers different surface and color options

The natural color of the metal creates a sense of quality and adds an aesthetic appearance to the projects. With the anodized surface treatment, metallic appearance, mirror-shine surfaces in silver, black, bronze and gold colors are obtained when desired. A wide variety of RAL color alternatives are available when a lacquered appearance is desired. It can be applied with electrostatic powder coating process in the desired RAL color. When desired, it is also possible to use the surfaces facing the interior and exterior environments with separate surface coatings and to provide integrity in the projects.
