ALUMIL SF85
Superior folding system for energy-efficient buildings
In a world where architecture strives for maximum openness, energy efficiency, and a perfect blend of design and function – SF85 represents the very top of the offer. This premium accordion system from ALUMIL is designed for projects without compromise, where insulation, aesthetics, and stability must be at the highest level.
It is the most efficient ALUMIL folding system when it comes to thermal and sound protection. Thanks to the advanced thermal break system and hidden mechanisms, SF85 manages to combine superior insulation with unobtrusive elegance. Whether used in a luxury villa, passive house, exclusive restaurant, or hotel zone, this system guarantees not only energy balance but also a completely new experience of space.
The sliding and folding of panels is quiet and precise. The system is activated by means of wheels on the underside, which provides additional stability and ease of operation. A load capacity of up to 200 kg per leaf allows application even on large openings, while the possibility of a flat threshold and full opening of the wall creates a sense of freedom and connection with the external space. Profiled rubber along the entire depth of the leaf enables excellent sealing and effective protection against drafts, which further increases the energy efficiency of the system. Multiple security points protect the interior without disturbing the appearance of the structure.
