The most ecological aluminum sliding windows

Are only wooden windows ecological?

When your client asks about ecological windows, probably the first raw material that comes to your mind is wood, which as a natural material automatically brings to mind an association with ecology.

What makes windows eco friendly? Should we consider aluminum, frameless windows and patio doors as ecological?

Material is undoubtedly an important element when assessing whether a window is ecological. Considering the production process of wooden windows, it can be concluded that they are not 100% ecological, for example in terms of varnishing and impregnation of wood. In our opinion, aluminum can be safely called an environmentally friendly material, which we describe below.

Why aluminum windows are ecological

Aluminum has a low density, while being an extremely durable material. Consequently, the production of aluminum profiles uses less material than when using other raw materials, and this means less harm to the environment.

From the point of view of ecology, you should also have in mind the exceptional strength of aluminum and the fact that aluminum profiles will last much longer than competing materials. Less replacement means less production globally, and less production means less environmental pollution. However, if there is a need to replace aluminum windows, this raw material can be recycled many times.

Do you know that?
System providers are constantly optimizing production in terms of “green building”. That is why other elements, such as spacers, insulators and gaskets, are also made of renewable raw materials. An example would be EPDM rubber gaskets, the production of which uses bioethanol obtained from sugar cane.

Ecological windows = energy-saving windows

The second key issue, even more important than the material itself, is the energy efficiency of the window. Yes! Which windows are the most ecological? Those that are energy efficient. The rule is simple – the better the thermal parameters of the window, the better for nature. Remember that we are talking about the perspective of several dozen years of use.

Various materials and aluminum used for the production of large, narrow-frame sliding windows combine features that translate into energy efficiency. Already a few years ago, aluminum systems caught up with PVC in terms of the heat transfer coefficient. Today, aluminum windows guarantee the best results in this regard.

Large glazing serves ecology

Large-size glazing of aluminum terrace windows also contributes to lower consumption of thermal energy and electricity to heat the building in winter and cool the interior in summer. Thick glazing units in frameless sliding doors achieve excellent parameters Ug = 0.5-0.6. In addition, they will make much more sunlight enter the interior.

Passive houses use aluminum

The energy efficiency of aluminum windows described above determines that passive houses most often use aluminum windows. Huge glass surfaces are installed in them, which, placed on the south wall, ensure the best use of natural light as an energy source.
