Noble, minimalist design gives ARTLINE windows a light and harmonious look.


The impression of extraordinary simplicity and lightness of the ARTLINE window was achieved as a result of the special attention that its creators paid to the mutual interactions of glass, all-glass windows and sophisticated lighting, as well as the preparation of a well-thought-out architectural concept of space in accordance with the slogan LIGHT IS MORE. Noble, minimalist design gives ARTLINE windows a light and harmonious appearance, even in the case of large-format fixed and sliding glazing.


The ARTLINE window can fulfill many different functions, making it ideal for numerous applications. Transparent glass exterior walls can be easily opened and closed, allowing the exterior to blend in with the interior. Each leaf can carry a load of up to 450 kg, which allows the use of large and heavy glass panes. The height of ARTLINE windows can reach 3.5 meters. Thanks to the huge size of the windows combined with the minimal visible width of the frame, the interiors of the buildings are literally bathed in light.
