The system is designed for the construction and performance of light-weight curtain walls,roofs, skylights and other complex structures.
The system has a self-bearing structure, composed of 50 mm wide aluminium mullions and transoms. Depending on the division pattern and external loads, the system provides a wide range of mullions and transoms varying in depth, with the moment of inertia Ix=58-1115 cm4.All mullions may be additionally strengthened by applying special internal aluminium profiles.The mullion-transom connection has masking strips to enable a proper water drainage and ventilation.
In order to achieve optimal thermal and acoustic insulation performance there has been appliedin the system a continuous thermal break called ” Nomaflex / NOMATEC XPE” with good insulating parameters and profiled EPDM glazing gaskets. It allows to obtain proper insulation class for thermal performance Uf=1,67-1,88 W/m2K, and it also allows for application of infills of thickness varying from 4 to 50 mm.
To reduce the mechanical working of mullions, any cut-outs in lateral surfaces of the mullionshave 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 standardsQUALICOAT or anodising in compliance with the requirements for QUALANOD trademark. Theminimum compulsory paint layer thickness shall be at least 60 microns for externalarchitectural use. The minimum anodic oxide layer thickness is 15 microns for externalarchitectural use.
The curtain wall system should be executed as per the design worked out individually for eachobject. Subject to the system documentation and structural analysis, the design should specifythe following: aluminium profiles (for mullions and transoms) / accessories to fasten mullionsto the building structure / transoms to mullions / details of connections and sealing betweenthe elements/ ventilation method and drainage.
While taking into account requirements connected with the function, location and geometry ofthe building, the wall should be designed in accordance with applicable requirements.
