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 be of poor quality or prone to aging.
Wall thickness and multi-cavity design: The wall thickness of the profile is also an important criterion for judging quality. High-quality UPVC profiles should have sufficient wall thickness to ensure their strength and durability. In addition, multi-cavity design is also a key factor in measuring profile quality. Multi-cavity design can better resist external pressure and deformation.
Anti-aging and anti-UV additives: When purchasing, you need to know whether the profile contains anti-aging and anti-UV additives. These additives can effectively extend the service life of profiles and protect them from ultraviolet rays, ensuring the aesthetics and performance stability of doors and windows.
Hardware accessories: The quality of hardware accessories also directly affects the overall performance and durability of UPVC doors and windows. Make sure the hardware accessories are made of metal and have good intrinsic strength and appearance quality. Avoid plastic hardware as their quality and longevity may be compromised.
Manufacturer and brand reputation: It is also very important to choose a manufacturer and brand with credibility and reputation. It is necessary to check whether the manufacturer has relevant production licenses and test reports to ensure the quality and safety of its products. At the same time, you can refer to the reviews and feedback of other consumers to make more informed purchasing decisions.
Installation and maintenance: Although this is not a direct detail when purchasing, it is also very important to understand the installation and maintenance requirements of UPVC doors and windows. Proper installation and maintenance can ensure the performance and longevity of doors and windows, so it is recommended to consult a professional or manufacturer for installation and maintenance advice before purchasing.
