<p>A thermally insulating window comprising a thermally insulating window framework having internal framework members supported adiabatically by a thermally insulating curtain wall and external framework members connected thereto through thermally insulating members; and a window body having a window sash mounted to the thermal insulating window framework capable of opening and closing and a panel member supported on the window casing at its periphery. The window further includes a sealing member made of thermally insulating material which is adapted to cover the whole of the outer surface of the window sash and to be in contact with the outer and upper portion of the external framework member. A thermally insulating area is provided at the junction of the window sash and the panel member and a thermal insulating space defined between the window casing and the thermally insulating window framework so that thermal insulation between the inner and outer sides of curtain walls is achieved. In the thermally insulating window, all heat transfer passages between the inner and outer sides of the curtain walls pass through one or more members of a thermally insulating material or through a thermally insulating space, whereby the thermally insulating window has a high thermally insulating efficiency as a whole.</p> |
