Observe the appearance of the profile: The appearance of high-quality UPVC profiles should be smooth, clean, uniform in color, and white with bluish tint. This is because anti-aging agents and anti-UV additives are added to the formula of high-quality UPVC profiles, giving them better aging resistance. On the contrary, profiles of poor quality may appear white with yellowing, have weak sun protection capabilities, and are prone to aging and cracking.
Check door and window hardware accessories: The quality of hardware accessories will also affect the aging resistance of UPVC doors and windows. High-quality hardware accessories should be made of metal, with high strength and long service life. Inferior hardware may be made of plastic, which will have a negative impact on the quality and service life of doors and windows.
Pay attention to details: The details of doors and windows are also an important factor in judging their aging resistance. For example, whether the welding angles are neat, whether sliding windows or casement windows are flexible and comfortable in use, whether doors and windows are tightly sealed, etc. Doors and windows with these details properly handled will have better aging resistance.
