FIELD: construction.
SUBSTANCE: invention concerns construction, particularly window and door structures. Profile system includes profile forming window case with window glass stopper, first profile forming first folding window casement for installation of stepped glasing connected to profile by glue joint, and second profile forming second folding window casement with external stopper for window glass and with devices for installation of inner plank holding glass fixated between window glass stopper and plank. Each folding window casement features socket for window fixtures, inner fold stopper and outer rest surface. Outer rest surface of first folding window casement is formed by outer window glass of stepped glasing. Distance B between middle axis of window fixture socket and inner side of inner fold stopper and distance A between outer side of inner fold stopper and middle axis of window fixture socket of both profiles match each other to form compatibility with the same profile of window case.
EFFECT: enhanced rigidity of profiles.
