PROBLEM TO BE SOLVED: To provide window heating equipment, in which thermal environment in a room is maintained comfortably by suppressing generation of cool air around a window, and preventing vapor condensation. SOLUTION: A heating unit (12) is built integrally in a lower chord (22) of a window frame (11) for fitting a paper sliding screen (10). Thus, the wind frame (11) is heated by the heating unit (12) to heat the sliding screen (10). |
