Abstract
A thermal insulating window comprising a thermal insulating window framework having internal framework members supported adiabatically by a thermal insulating curtain wall and external framework members connected thereto through thermal insulating members; and a window body having a window casing 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 thermal insulating material which is adapted to cover the whole of the outer surface of the window casing and to be in contact with the outer and upper portion of the external framework member. A thermal insulating area is provided at the junction of the window casing and the panel member and a thermal insulating space defined between the window casing and the thermal insulating window framework so that thermal insulation between the inner and outer sides of curtain walls is achieved. In the thermal insulating window, all heat transfer passages between the inner and outer sides of the curtain walls pass through one or more thermal insulating material or thermal insulating space, and therefore the thermal insulating window has a high thermal insulating efficiency as a whole.
