The present invention relates to a frame for windows and doors with excellent thermal insulation and air tightness. More specifically, a pair of frames are configured to be connected to indoor and outdoor side exterior frames by connecting an insulation frame made of a PVC material with excellent thermal insulation to a stainless steel or steel exterior frame which is disposed on the indoor and outdoor sides. The frame comprises a fixing member in which both end parts of the exterior frame are inserted into the insulation frame and effectively cuts off heat to be transferred between the glass and the exterior frame in the vicinity of a glass connecting part, thereby improving thermal insulation and air tightness. |
