<p>PROBLEM TO BE SOLVED: To prevent the cooling of a room while reducing the heat transfer from the warm air of a room to the outside air when 'the cooling convection in the direction opposite to the convection to be generated when heating-up' is generated in relation to the warm air of a room from a glass window, an iron door, an aluminum sash door and a show window or the like by the outer air lower than the room temperature and when the cooling of the room is accelerated by heat transfer of the warm air from the glass window, the iron door, the aluminum sash door and the show window or the like to the outer air by fitting a hollow layer sheet 11 divided into small divisions to the inside of the glass window 3 of the room. SOLUTION: A hollow layer sheet 11 formed by welding or adhering a thin plate sheet 9 made of the same material 7 with a hollow layer 1, which is formed by forming, welding or adhering the material 7 such as paper, vinyl chloride or polyethylene and dividing into small divisions, and divided into small divisions, is adhered to the inside 5 of a room provided with a glass window 3.</p> |
