FORTIS 75
An advanced member of the Fortis series, FORTIS 75 brings together high thermal performance and modern design. Developed for cold climates, the system offers durability, aesthetics and functionality.
Its design uses a limited number of corner cleats, with shared cleats across the series to simplify stock management, storage and shipping. Standard machinery settings help speed up production. The Euro and PVC sash configurations are compatible with accessories from various hardware manufacturers. Alternative sash profiles allow the same glazing bead profile to be used in fixed and opening sections, creating a modern, flush appearance across glazed surfaces.
The 34 mm thermal barrier supports insulation in cold climates. Concealed sash hardware keeps opening sections out of sight from the exterior, giving the façade a clean appearance. A multipoint locking restrictor system and hardware capable of supporting up to 150 kg contribute to safe operation. Outward-opening and tilt options accommodate different architectural requirements.
