H55 - hybrid steel

The first-ever steel curtain wall without welding

While the H55-hybrid steel is the very first fully thermally broken curtain wall in steel, its processing, manufacturing, and installation are completely identical to the H60-hybrid aluminium system. And when it comes to water and airtightness, the H55-hybrid steel approaches the exceptional performance of the H60-hybrid.

This revolutionary system doesn’t have a single millimetre of welding, making it the perfect fit for sleek, sophisticated constructions. Moreover, the H55-hybrid steel has a real thermal break and flaunts an EI60 fire resistance. Of course, much like our other solutions, the H55-hybrid steel allows for foolproof installation from the inside of the building.
