PURPOSE: To improve the heat-insulating properties of a window and a wall, to reduce site work and shorten the period of the execution of works.
CONSTITUTION: A new facing material 30 and a new window frame 31 are installed on the existing facing material 4 and existing window frame 11 of a building 1, and the new window frame 31 and the new facing material 30 are continued. Since the heat-insulating properties of a window section can be improved while an external wall is doubled by the existing and new facing materials 4, 30 by remodeling the new window frame 31, the heat-insulating properties of a window section can also be enhanced, and energy is conserved and operating cost is reduced at the time of air conditioning. Since the existing facing material 4 and the existing window frame 11 are not removed, site work is reduced, and the period of the execution of works can be shortened.
