Ersaş Systems offers an ideal solution for hot climate regions with its Fortis 55N series, which prioritizes efficiency and durability in production. The Fortis 55N provides economic advantages thanks to its non-insulated structure, offering a practical alternative for architectural projects with its simple form and high performance. Designed with a minimal number of corner blocks, the system reduces stock, storage, and shipping costs thanks to its common block structure across all series.

Thanks to the grid-alternative wing profiles, the same frame profile can be used in both fixed and opening areas, thus achieving a modern, uniform appearance on glass surfaces. Fortis 55 N has been developed for projects seeking economical solutions without compromising on quality and performance. It is the ideal choice for those seeking a durable, reliable, and aesthetic system in warm climates, with the Ersaş Systems difference.
