Due to the noise-reducing, energy-efficient, eco-friendly, water-resistant, and fireproof features of broken bridge aluminum doors and windows—and given their growing popularity in the market—some unscrupulous businesses have begun deceiving consumers through deceptive practices. As a result, learning how to accurately assess the quality of broken bridge aluminum doors and windows has become quite an art form.
To determine the quality of these products, you can examine several key factors: the surface finish of the profiles, the internal structure of the cross-section, and the positioning of the thermal break strips. High-quality broken bridge aluminum profiles boast a smooth, flawless surface without any protrusions, with a natural-looking sheen that feels perfectly even to the touch—definitely not rough or irritating.
When it comes to the cross-sectional structure, pay close attention to the angles of the aluminum alloy profiles. Specifically, ensure that each cut angle is precisely 90 degrees, as this is critical for both functionality and durability. Additionally, check the thickness of the profile—Warren’s products meet national standards in both profile design and material thickness.
To assess the quality of broken-bridge aluminum doors and windows using the thermal break strip, pay close attention to the material of the strip. The PA66 thermal break—commonly known as the nylon strip—is particularly noteworthy for:
1. Its high melting point, exceptional heat resistance, and self-extinguishing properties.
2. A superb balance of toughness, durability, electrical performance, and other key physical characteristics.
3. Excellent resistance to oils and outstanding chemical stability.
4. Superior wear resistance, creep resistance, and long-term aging performance.
The simplest way to distinguish between PA66 and PVC is by using fire: PA66 has a melting point of 220°C, so it typically won’t deform or ignite under normal conditions. In contrast, PVC melts at just 80°C, making it highly susceptible to degradation—or even catching fire—when exposed to heat. That’s why it’s crucial to identify the exact material of the thermal break.
