Os Minimal System     Transparency in space...


Alport responding to the most innovating trends into the global aluminium frames market is proud to present OS Minimal system.  Their modern minimalistic appearance serves inspired architectural designs, satisfying the most demanding requirements in energy efficiency and functionality.


 Up until now, large volume aluminium profiles were used as static element of window doors, so to cover large widths and heights. Today, minimal aluminium systems use tempered/security glasses which with their durability to direct hits, pressures and vibrations, offer the potential to use them as the main structural element of the windows, resulting in almost frameless transparent surfaces.

OS system sliding windows and doors can be easily integrated in exclusive villas, free standing houses, apartments, business complexes aiming at opening interior living spaces with unobstructed views to the outside

The system offers a variety of system profiles configuration which are serving ideally the clean lines and balanced proportions of the modern contemporary architectural designs.  OS 2 system, with large-scaled double glazed tempered 8mm windows can be fully integrated into floors, walls and ceiling leaving visible only a slim leaf profile facing of 20mm and can reach heights up to 3.5 meters.

Additionally, System OS 3 profiles with triple energy Tempered glasses we can cover glass areas up to 14m² achieving heights up to 4.5 meters. Pivoting doors and fixed elements profiles complete the system for limitless individual solutions in all constructions satisfying designer and client requirements.


Easy operation

Stainless steel high performance tracks and specially designed rollers guarantee an easy manual operation of leafs up to 400 kg weight while you experience a smooth and silent opening. Telescopic like opening variants is also possible for large openings. Alternatively, operation of sliding elements (weight up to 1000kg) via electrically driven motors is available upon request for maximizing user comfort.
