Aluminum alloy doors and windows have steadily overtaken traditional PVC doors and windows in recent years due to their long-lasting material, energy efficiency, customizable appearance, and environmentally friendly recycling. They are now the standard option for engineering construction and home decoration, offering users a low-carbon and long-lasting experience.

Durable Material: Strong Weather Resistance, Longer Service Life
● Doors and window profiles made of aluminum alloy are extremely strong and resistant to deformation. After anodizing or powder coating, they have a service life of more than 30 years and can withstand changes in temperature, humidity, and acid-base conditions. They remain stable and long-lasting in damp southern regions, coastal regions with high humidity, and northern regions with significant temperature variations.
● On the other hand, prolonged exposure to UV light and extremes of temperature can cause PVC doors and windows to yellow, embrittle, or soften, which reduces their ability to seal. Compared to aluminum alloy doors and windows, they have a far shorter actual service life of only 15 to 20 years.

Energy Efficiency: Broken-Bridge Tech Reduces Consumption
● Driven by the "dual carbon" policy, aluminum alloy doors and windows meet the first-level energy-saving standard by preventing heat transfer through "broken-bridge" technology (insulation strips embedded in profiles). Their thermal conductivity (K-value) is as low as 1.8W/(㎡·K) or less, and some high-end products reach 1.4W/(㎡·K). With their weather-resistant strips and multi-seal design, they can cut the energy use of air conditioners by 15% in the summer and heating by 20% in the winter.
● The energy-saving effect of standard PVC doors and windows is significantly diminished by their K-value of 2.5–3.0W/(㎡·K); additionally, their sealing strips are prone to aging, which further reduces energy efficiency after three to five years.

Customizable Appearance: Style Adaptation for Personalized Needs
● By using different surface treatments, aluminum alloy doors and windows can display textures like metallic matte and wood grain, supporting narrow-frame and large-span designs. They maximize the amount of natural light and fit into a variety of home styles, including new Chinese and modern minimalist.
● Because of material limitations, PVC door and window profiles are typically light-colored, wide (more than 80–100 mm), and difficult to achieve complex textures, making them unsuitable for individualized needs.

Eco-Friendly Recycling: Recyclable for Sustainability
● All aluminum alloy is recyclable. It has a recycling rate of more than 90% and can be melted and reprocessed without containing any hazardous materials after scrapping. Just 5% as much energy is used by recycled aluminum as by primary aluminum.
● PVC doors and windows have a 30% recycling rate, which clearly shows inadequate environmental friendliness, and landfilling is difficult to decompose and easy to cause pollution. These materials may also release harmful gases during production and recycling.
