The present invention relates to a casement (1) for a glass window or a leaf for a glass door, a window or door frame and a window system containing a casement and a window frame. The casement or leaf comprises an insulating material layer arrangement located between two hollow profiles (3, 4). The insulating material layer arrangement has at least one first insulating layer (5) which is configured for high strength, and at least one second insulating layer (6) which is configured for high thermal insulation. Between the two wood profiles (3, 4), a lateral insulating layer (8) which is configured for high thermal insulation is arranged substantially perpendicularly to the direction of extent of the insulating material layer arrangement. |
