A window frame system for fixing at least a first panel, includes at least a first window frame structure which includes at least a first window frame profile having at least first and second holders, and at least a first thermally insulating element with sixth and seventh holders. The second holder and the sixth and/or the seventh holder of the first thermally insulating element include at least one internal corner with a radius smaller than 0.5 mm. In this way, the dimensions of the window frame profile may be smaller than in the known window frame profiles. This may be advantageous for the total insulation value of the window frame system and the quantity of material required/used for the window frame profiles. Also disclosed is a thermally insulating element, a method, a window frame structure, a flexible profile, a control system and a sun protection system.

A window system includes a window frame spatially separated from a subframe. The subframe has a receptor leg spatially separated from a wedge bead by a thermal break. The receptor leg includes a channel for directing liquid away from the subframe; a first gasket disposed between the receptor leg and the window frame at a first location; and a second gasket disposed between the receptor leg and the window frame at a second location. Liquid passing between the first gasket and the window frame is directed into the channel via the second gasket.

The present invention relates to a glazed element with improved water tightness comprising a fixed frame, at least one gasket G.sub.a and at least one frameless inwardly openable casement wherein the casement comprises a multiple glazing comprising in external position a glass pane including at least one thermally treated glass sheet, the glass pane has an overall bow on at least its bottom edge of at most 3.0 mm/m and the gasket G.sub.a is such that it is in continuous contact with the fixed frame and with at least the bottom edge of the glass pane, when the glazed element is in closed position.

A window system has a window frame that surrounds a window unit. The window frame has a glazing leg with an outer wall and an inner wall. The inner wall forms a J-shaped stem, which forms a J-shaped channel between the inner wall and the outer wall. A first gasket engages with the outer wall, and is maintained in compression between the outer wall and the window unit. Likewise, a second gasket engages with the inner wall, and is maintained in compression between the inner wall and the window unit.
