The present invention relates to an insulation frame for windows and doors with improved thermal insulation properties and structure solidity. More specifically, a plurality of heated-insulating hole layers are secured in the internal side of the insulation frame and the thermal insulation improved, and the structural solidity is enhanced while a metal exterior frame and a PVC extrusion maintains integrity to which there is no flexibility. The heated-insulating hole layer formed in the internal side of the PVC extrusion with no thermal conductivity can significantly improve the properties of thermal insulation, and simultaneously block a thermal conductive phenomenon between the indoor and the outdoor. The present invention allows the PVC extrusion and the exterior frame to maintain a mutual secure integrity while a staggered fixated portion formed on the exterior frame is latched and fixated in a dual latching piece or a single latching piece formed on the PVC extrusion. |
