UPVC Windows & Doors are a type of doors and windows with characteristics of corrosion resistance and weather resistance. After using UPVC Windows & Doors for a period of time, some UPVC Windows & Doors may be deformed. What is the reason for the deformation of UPVC Windows & Doors? Today, Baydee will answer them one by one for you.

1. The deformation of plastic-steel doors and windows may be caused by the material of the plastic-steel doors and windows. The wall thickness of the plastic-steel material is relatively thin. If the cavity design of the plastic-steel doors and windows is unreasonable, the profile material of the plastic-steel doors and windows will be softened, resulting in deformation.

2. The steel lining of the plastic-steel doors and windows is not fastened with the profiles in accordance with the standard, which may also lead to the deformation of the plastic-steel doors and windows. The steel lining of the plastic-steel doors and windows and the profiles are not tightly combined. It is necessary to use screws to fasten the profiles together to fix each steel lining. There are no less than 3 screws, and the spacing is not more than 300mm. The distance from both ends of the profile is not more than 100mm.

3. The connection method between theUPVC Windows & Doors and the wall is improper, and the frame is not filled with soft materials, and the formation of "expansion joints" will also lead to the deformation of the UPVC Windows & Doors.
