At the same time, the use of sub-frames makes it easier to control the installation quality of doors and windows. The following Joyfident aluminum clad wooden window suppliers tell you what a subframe is:
Many people do not know that there are subframes when installing doors and windows. The sub-frame of doors and windows is called the attached frame and the protective frame. According to the material, it can be divided into: steel sub-frame, aluminum alloy sub-frame, wooden sub-frame, etc.
The window frame is fixed on the wall and used to install doors and windows. It is generally used for 70 series and below profiles. If the window needs to be covered with a window cover (window entrance), the tiles need to be pasted around the window, and the top of the window needs to be suspended. It is necessary to add an additional frame, because the frame of the 70 series and below profiles is relatively narrow, and there will be obstacles to the opening of doors and windows.
The importance of the window sub-frame is to guide the plastering, which not only ensures the cleaning and damage of the doors and windows, but also ensures the quality of the doors and windows. Generally, doors and windows and large-scale projects are widely used. If you don’t have attached frames, you must first install the main frame of the doors and windows.

The sub-frame plays a role in sizing and positioning the doors and windows. It is more conducive to the thermal insulation and sealing performance of doors and windows, especially the expansion and contraction phenomenon of plastic steel doors and windows due to thermal expansion and cold contraction, which causes gaps in the edges of doors and windows, affects the appearance, and reduces the functions of anti-seepage, energy saving, compression resistance and shape resistance. .
