Observe profile quality: UPVC profiles are the core part of UPVC doors and windows, and their quality directly affects the performance and service life of doors and windows. A good UPVC profile should be a reasonably designed multi-cavity body with moderate wall thickness, bluish white color and smooth surface. At the same time, the profile formula should contain anti-aging and anti-UV additives to enhance the durability of doors and windows.
Check the hardware: The hardware of high-end plastic steel windows are all made of metal, and their inherent strength, appearance, and usability directly affect the performance of the doors and windows. When purchasing, you can check the material, weight, appearance and workmanship of the hardware to ensure that they meet high quality standards.
Pay attention to assembly quality: In addition to profiles and hardware, assembly quality is also a key factor affecting the quality of UPVC doors and windows. You can observe whether the appearance of the doors and windows is smooth and intact, whether the welding angles are neat, whether the hardware is complete, etc. At the same time, you can also try sliding doors and windows to feel whether they are compact and flexible.
Consider energy-saving performance: High-quality UPVC doors and windows should have good thermal insulation properties, which can effectively reduce the temperature difference between indoors and outdoors, reduce the use of air conditioning and heating, thereby saving energy consumption. When purchasing, you can pay attention to the thermal insulation performance parameters of doors and windows and related certification marks.
