<p>The outer side of the leaf (4) carries a braket frame (12). It is necessary to prevent the formation of condensation water on the window panes (6, 14) and to provide for a sufficient thermal and acoustic insulation. To this effect, a labyrinth joint (18, 22) is arranged between the two frames (4, 12) so as to obtain a vapor pressure balance between the outer side of the glazing and the space between the two window panes.</p> |
