What is the relationship between wall thickness and performance of UPVC profiles?

Strength and pressure resistance: The greater the wall thickness of the profile, the higher its overall strength and pressure resistance. This means that thicker wall thickness can better resist deformation or cracking when subjected to external pressure or impact, ensuring the structural stability and safety of doors and windows. Sound insulation and thermal insulation performance: […]

Appearance and color: First, observe whether the surface of the UPVC profile is smooth and the color is uniform. High-quality UPVC profiles usually appear bluish-white or bluish-white. This color is not only beautiful, but also has good anti-aging properties. Avoid choosing profiles that are yellowish in color or have obvious color differences, as they may […]

First of all, these sealing materials have excellent weather resistance and can resist the erosion of sunlight, rain and various climatic conditions for a long time, thereby maintaining stable performance and not easy to age or deform. Secondly, these sealing materials also have good elasticity and wear resistance, and can maintain a tight fit during […]

Visual inspection: Observe the glossiness of doors and windows from a distance to see if there is any obvious color difference. Use a ruler to measure the dimensions of doors and windows and check for deformation. Touch the surface of the door and window at close range with your hands to check whether it is […]

Observe the surfaces of doors and windows for obvious scratches, cracks or discoloration. Check whether the corners of doors and windows are intact and whether there are any signs of impact or damage. Pay attention to check whether the sealing strips of doors and windows are intact and whether they are falling off or aging. […]

Generally speaking, if the doors and windows are frequently opened and closed, or are in a relatively harsh environment (such as frequent contact with rain, sand, dust, etc.), then the frequency of maintenance should be higher. This ensures that the performance and appearance of the doors and windows are maintained in good condition. Specifically, every […]

Avoid using sharp tools: When cleaning doors and windows, do not use sharp cleaning tools to avoid scratching the surfaces of doors and windows. It is recommended to use a soft cloth or sponge with a neutral detergent for cleaning. Prevent falling from high places: If the doors and windows are located in a higher […]

Accurate measurement: Before installation, be sure to accurately measure the size of the door and window openings to ensure that the UPVC doors and windows match the openings to avoid loose installation or being too large or too small. Installation specifications: Install according to the installation guide provided by the manufacturer or the recommendations of […]

First of all, when installing, make sure that the gap between the door, window and wall is appropriate, and use special sealant or sealing strips to fill it to avoid air leakage, water leakage and other problems. These sealing materials should have excellent weather resistance and aging resistance to ensure long-term use. Secondly, the hardware […]

First of all, its corrosion resistance is particularly strong and can resist the erosion of strong acids and alkali, which makes it neither rust nor scale during use and is very durable. Secondly, the inner wall of the Upvc profile is very smooth, which makes the resistance of the fluid in the pipe very small, […]
