To achieve optimal thermal and acoustic insulation performance, a continuous thermal break with good insulating parameters and profiled EPDM glazing gaskets. It allows to obtain proper insulation class for thermal performance Uf=1.93-2.12 W/m2 K, and it also allows for the application of infills of thickness varying from 10 to 40 mm.

To reduce the mechanical working of mullions, any cut outs in lateral surfaces of the mullions have been eliminated and the installation of infills (DGU or Sandwich panels)is performed with clamping strips – fixed with self-tapping screws made of stainless steel A2.
The profiles can be paint according to the RAL palette in full compliance of quality standards QUALICOAT or anodizing in compliance with the requirements for QUALANOD trademark. The minimum compulsory paint layer thickness shall be at least average 60 microns for external architectural use. The minimum anodic oxide layer thickness shall be at least 15 microns for external architectural use.

The curtain wall system should be executed as per the design worked out individually for each object. Subject to the system documentation and structural analysis, the design should specify the following: aluminum profiles (for mullions and transoms) / accessories to fasten mullions to the building structure / transoms to mullions / details of connections and sealing between the elements/ ventilation method and drainage. While taking into account requirements connected with the function, location and geometry of the building, the wall should be designed in accordance with applicable requirements.
