K'energy: GlobalWall® und GlobalRoof®

K‘energy is a patented multi-functional façade and roof system that complies with the strict requirements of thermal insulation and modern architectural design.

The bases of K’energy systems are vertically assembled sandwich panels with coilcoated steel sheets and a PUR core that integrate building physics functions: impermeability, fire resistance and high performance thermal insulation with an U- value of under 0,15 W/m2K. At the same time, the system allows for quick installation and a speedy weatherproofing of the building.

The connection between the functional basis and the aesthetic cladding is a specially shaped rack that is placed into the longitudinal overlap of the sandwich panels. This way, a vertical linear support is created for the outer cladding. The space between steel sheets of the bases and the outer cladding creates an additional insulation layer or vertical air ventilation. 

Freedom of design

Different steel façades from the Arval offer can be assembled to th K’energy-base. Furthermore, the system also allows for fixing systems for glass, ceramic, timber or plastic elements.
