DETAILED DESCRIPTION

[0067] FIG. 1 represents a cross sectional view of the bottom edge of a glazed element in open position. It shows a fixed frame 3, a gasket G.sub.a 1 and a gasket G.sub.b 2. Gasket G.sub.a 1 is here fastened to the fixed frame 3 and has a deformable lip. The shape and dimensions of gasket G.sub.a 1 illustrated presents a good balance between the aesthetics aspects, the water evacuation and the force to close the casement. Gasket G.sub.b 2 is significantly bigger than G.sub.a as it is invisible when the glazed element is in closed position. It is inwardly located with regards to gasket G.sub.a.

[0068] FIG. 2 represents a cross sectional view of the bottom edge of a glazed element in closed position. It shows namely the same elements as in FIG. 1. The bottom edge of the fixed frame 3 comprises a draining system 6. The inwardly openable casement 4 at its bottom edge has no frame element on the side towards the exterior of the building and has a frame element 9 on the side towards the interior of the building. It comprises a double glazing 5 with a glass pane 8 in external position consisting of a single thermally treated glass sheet. The gasket G.sub.a 1 is in continuous contact with the fixed frame 3 and the bottom edge of the glass sheet 8. The gasket G.sub.b 2 is in continuous contact with the fixed frame 3 and with the frame element 9 of the casement 4. Gaskets G.sub.a 1 and G.sub.b 2 define between them a peripheral interspace 7 running between the fixed frame 3 and the casement 4.

[0069] FIG. 3 represents a cross sectional view of the bottom edge of a glazed element showing the same elements as in FIG. 2, but the glass pane 8 consists of a laminated glass comprising one thermally treated glass sheet and another glass sheet separated by a polymeric film.

[0070] FIG. 4 represents a cross sectional view of the bottom edge of a glazed element where the inwardly openable casement 4 has a frame element 9 at its bottom edge, which is invisible when the glazed element is in closed position. It comprises a triple glazing with a glass pane 8 in external position consisting of a single thermally treated glass sheet. The gasket G.sub.b 2 is in continuous contact with the fixed frame 3 and a glass sheet 10 of the multiple glazing of the casement 4.

[0071] FIG. 5 represents a cross sectional view of the vertical junction between two casements 4 and 11 in closed position, which have no mullion between them, but frame elements 9 are present between the glass sheets. The exterior glass pane 8 of casement C.sub.b 4 is a thermally treated glass sheet. The gasket G.sub.c 12 is fastened to a frame element 9 of the vertical edge of casement C.sub.a 11 which is contiguous to casement C.sub.b 4. The gasket G.sub.c 12 is in continuous contact with the vertical edge of casement C.sub.a 11 and the glass pane 8 of casement C.sub.b 4. The gasket G.sub.d 13 is fastened to the vertical edge of casement C.sub.b 4 contiguous to casement C.sub.a 11. When the glazed element is in closed position, gasket G.sub.d 13 is in continuous contact with a glass sheet of casement C.sub.a 11 and is located inwardly with respect to gasket G.sub.c 12.
