The Hyline aluminium frame series is a modern choice that combines high aesthetics and functionality, ideal for spaces requiring large openings that allow abundant natural light and unobstructed views in all their glory.
The frames are designed to accommodate double or triple glazing up to 48 mm thick, in windows reaching heights of up to 6 meters and total glass surfaces up to 18 m². This is an impressively robust system that delivers excellent thermal and acoustic insulation performance even under the most extreme conditions. At the same time, it offers a minimalist appearance with ultra-slim sash profiles and the option for a recessed bottom track, ensuring minimal visible aluminium and maximum glass surface exposure.
A key advantage of the Hyline series is its flexibility. In terms of typologies, it offers the option of single, double, or triple tracks with corner or central openings. For security, beyond multi-point locking, it also allows for the integration of locks—electromagnetic or key-operated—as well as the option of bulletproof glass.
Hyline frames elevate the spatial experience by offering both elegance and functionality. They can be combined with shading or blackout systems and insect screens.
