Ponzio WS 50 ventilated facade

The system is made of extruded EN AW-6060 aluminum alloy profiles in compliance with EN 573-3 and EN 755-2 in the supply state EN 515, suitable for anodic oxidation and surface painting, in bars of commercial length of 7,00 meters with dimensional tolerances and thicknesses according to what is foreseen from the UNI EN 755-9 and EN 12020-2 standards. The mullions, to be chosen according to the application diagrams, will create a substructure on which different types of materials can be applied "dry" finish mechanically fixed with a special accessory that will allow alignment even after the pose. They can be applied: • Aluminum sheet panels • Composite panels • Aluminum frame with structural gluing glass • Aluminum frame with "semi-structural" glass The system has been designed to be externally applied to weather protection already existing moldings, therefore, must be designed in such a way as to prevent splashes and percolations rainwater or drainage can reach the masonry below. The system, by its nature and function, has no resistance to air and water. To obtain thermal insulation, it is necessary to use an insulating mat adhered to the plugging from to cover. The system is also prepared for the creation of the "chimney effect" where there is a need for improve thermal performance. In this case careful planning is necessary that takes into account of the geographic position, of the shape of the building and its exposure to the movement of the sun in the various periods of the year.

The size of the mullions must be chosen based on the static calculations performed to meet the requirements provided for by the regulations in force relevant to the installation site. STRUCTURE ATTACKS The connections to the structure are made using anchoring brackets prepared for adjustment in the direction of the three orthogonal axes in order to compensate for the constructive inaccuracies of both the structure of the building both of the facade. They will be produced in 6060 EN 515 aluminum alloy, complete with connection bolt in stainless steel and in any case in compliance with the provisions of the UNI 3952/88 standard. Functionally to the dimensions of the established façade module, similar to the one implemented for the mullions, also for the anchoring brackets the verification calculation must be carried out. EXPANSIONS The system is composed of components that, assembled, are suitable to compensate for the normal movements of the facade and building in a silent way. However, in the implementation phase, it will be necessary to respect all the indications provided by the system engineer, in particular the use of all the accessories and gaskets indicated, tolerances, exact measurements of the workings and perform correct installation. SURFACE FINISH The surface finish of the profiles must be carried out observing the criteria set by the directives for obtaining the Qualanod Mark, for anodizing and Qualicoat Mark, for painting. COMPOSITE PANELS Composite panels consist of two outer layers of sheet, generally of aluminum, of thickness of 5/10 (or anyway suitable for the type of material) bound by a thick extruded thermoplastic core minimum 3 mm. The material must belong to the fire resistance class 1 . For the installation they will have to be boxed, machined and hooked as opportunely indicated in the catalog. Particular attention must be paid to the coupling of different materials to avoid the phenomenon of the galvanic couple.
