The present invention relates to a double window having a blind screen installed therein and capable of performing external blocking when wound or unwound and, more specifically, to a double window having a blind screen installed therein and formed into a double structure, thereby improving thermal insulation, soundproofing, and an external blocking force, and easily controlling the degree of the external blocking. According to the present invention, a window frame member has a first and a second window glass member which forms the double window having the blind screen which is installed therein and has two layers of the double structure, thereby improving the thermal insulation, the soundproofing, and the external blocking force. Especially, according to the present invention, the blind screen has a transparent part and an opaque part, so the degree of the external blocking can be easily controlled depending on the degree of matching between the transparent part and the opaque part, thereby obtaining user convenience. |
