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.

Aluminum windows are highly resistant to weather conditions (for instance, aluminum windows can be found in a structure on the Lomnický Štít mountain in Slovakia) and their surfaces require almost no maintenance.

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.
