Frequently Asked Questions
Q: How to judge the quality of aluminum alloy door and window profiles?
A: Three key checks: 1. Surface: High-quality profiles have a smooth, even finish with consistent color. 2. Thickness: Main profile wall thickness should not be less than 1.8mm. 3. Material: Opt for primary aluminum alloy (e.g., grade 6063-T5) rather than recycled aluminum.
Q: Why do some aluminum doors/windows operate roughly or make noise?
A: Main causes include: dirt or debris in the tracks; poor quality or worn hardware (like rollers, hinges); improper installation causing frame distortion; or insufficient profile rigidity leading to friction.
Q: What are "Thermal Break" aluminum alloys? What are their advantages?
A: A thermal break profile has a strip of low-conductivity material (typically PA66 nylon) inserted between interior and exterior parts. Its main advantage is superior thermal insulation, significantly reducing heat transfer for better energy efficiency and sound insulation.
Q: How to check the sealing performance of aluminum doors and windows?
A: Focus on the gaskets. High-quality products use EPDM gaskets for good elasticity. Check if they are continuous and compress tightly. You can try pulling a sheet of paper from a closed sash—it should be difficult to remove if sealed well.
Q: What are the considerations for high-rise building installations?
A: Safety is paramount. High-strength profiles and tempered safety glass are mandatory. Hardware must have high load-bearing and wind pressure resistance. Installation must be secure, often using galvanized steel brackets for reinforcement.
