Aluminium profile system intended to accomplish thermal insulated sliding windows or sliding segments for external elements of constructions, for example loggias and balconies. The systems allows to use fillings, of 23-30 mm thickness. The structural depth of the profiles equals 46 mm for frames, 73/95 mm fOr double track frames, 131,5/153,5 mm for triple track frames. Possibility of achieving the minimal width of the central post - 37 mm – provides slenderness and stiffness of the construction. Ponzio hardware is installed in SL600tt EVO sliding system. Thanks to special EPDM gaskets, made of synthetic rubber, used on the perimeter of each of the sliding segments, we achieve high tightness of the construction. Characteristics of system: precise relation to other Ponzio systems possibility of making corner connections at 90° or 45° degrees by cutting the end of the profiles
