PROBLEM TO BE SOLVED: To sufficiently soften the direct sunlight streaming into a room and to intercept heat, thereby suppressing the temperature rise of the room and improving convenience because of eliminating conventional trouble of shielding an opening face by moving a window screen whichever sash is opened. SOLUTION: In this window device with a window screen, double sliding type sashes 3, 4 for opening/closing an opening 1 of a building are installed in a sash frame 2 fitted into the opening 1, and the window screen is movably installed outside the sashes 3, 4. The window screen is composed of double sliding window screens 5, 6 capable of shielding the opening 1 in a totally closed state in a double sliding manner. COPYRIGHT: (C)2006,JPO&NCIPI
