The present invention relates to a frame for windows and doors with improved insulation which may be commonly used for windows and doors of various configurations such as normal windows, glass walls inside a building, and tempered glass doors. An objective of the present invention is to provide a frame for windows and doors with improved insulation which is formed of a triple structure wherein stainless auxiliary frames are fitted and assembled to both sides of a main aluminum frame and the main frame is connected with an insulation member to be divided into left and right sides, thereby improving insulation, improving the appearance, improving corrosion resistance to provide convenience in maintenance and management, and filling the main frame with insulation filler to improve overall bending strength in order to improve durability. The present invention is formed of a triple structure wherein the auxiliary frames formed by bending stainless plates are fitted and assembled to both sides of the main aluminum frame, wherein the hollow main frame has left and right members connected to each other with two non-metallic connection members in order to improve insulation and has a first forming groove and a second forming groove into which the connection members are vertically inserted to be divided into the left and right members when being cut, the first forming groove and the second forming groove are blocked by a floor plate, and a slot for coupling a blocking plate is formed on the lower portion of the floor plate of the second forming groove to couple the connection member to the first forming groove and seal the floor of the second forming groove by the blocking plate coupled to the slot for coupling the blocking plate while the floor plates of the first and second forming grooves are cut. |
