Aluminum windows

Aluminum windows are the option that is often selected by designers for residences, administrative buildings and apartment buildings. Aluminum windows fit well into large glazed areas and whole facades. They are also becoming more and more popular for family homes.

Owing to its strength, aluminum protects the window from inadvertent or intentional damage. Aluminum retains its shape, so the window will fit and perform well during its entire service life, even if used in busy locations.

If the glass, frame and gaskets are selected appropriately, the thermal insulating properties of windows made of top-quality aluminum profiles will match those of plastic or wooden windows.

When buying your aluminum windows from us, you can extend your purchase with an aluminum entrance door with the same design.

RI OKNA’s aluminum windows meet all the demands for a precise fit, long-term use and an impressively modern look.

We manufacture aluminum windows in sizes, shapes and configurations matching the specific project they are intended for. The maximum window sizes you can order are different for the different profiles.

The aluminum windows are fitted with top-quality SIEGENIA, SAVIO RIBANTA, SOBINCO or WINKHAUS hardware.

Please specify your requirements for the size(s), shape(s) and design(s) in your inquiry.


The surface of the aluminum profiles is finished by powder coating, plastic film coating or anodizing. You can select your favorite color from the RAL chart, which containing 200 colors.


Glazing plays a key role in the window’s heat- and sound-insulating capacity. Safety is also an important aspect, particularly for large aluminum French doors. We use top-quality glass panes from the foremost European manufactures in our aluminum windows.
