The present invention relates to an insulated window. A first insulator receiving portion (A) and a second insulator receiving portion (B) are formed in members forming a window frame (10), respectively. A third insulator receiving portion (C) is formed in members forming a window frame (20). An insulator (30) is filled in each of the first to third insulator receiving portions (A, B, C). The first insulator receiving portion (A) is formed in an internal hollow portion of the member forming the window frame (20). The second insulator receiving portion (B) is formed on an upper portion of the first insulator receiving portion (A) on a straight line with respect to a lower member (12) among upper and lower, and left and right members of the window frame (10) while being formed in a rail (15) provided in the member forming the window frame (20). The third insulator receiving portion (C) is formed in an internal hollow portion of the member forming the window frame (20). The height of the top of the second insulator receiving portion (B) is formed to be equal to or higher than the height of the bottom of the third insulator receiving portion (C). By the above configuration, the insulated window may improve insulation performance and may have sufficient strength to solidly support the window even when a load acts on the window. |
