[0002] At present, the thermally insulated aluminum products in the door and window market are without exception made of aluminum inside and outside with a middle insulation strip. Some products simply stack materials, which actually does not help to improve performance at all. The structure of the door and window system determines that designers need to make innovative structural designs within a very small size range. At the same time, the structural design must also meet the coordination conditions of various aspects, which is not an easy task. Therefore, the products in the door and window market are seriously homogenized.
