Aluminum alloy windows come in two main types: regular aluminum alloy doors and windows, and the more advanced thermal break aluminum alloy doors and windows. These windows boast an attractive appearance, excellent sealing properties, and superior strength, making them a popular choice for architectural projects.
Thermal break aluminum windows have become increasingly common in home renovations, often used to enclose balconies. They provide better insulation compared to traditional aluminum windows, addressing issues like heat transfer that plagued earlier models.
Basic Definition:
English Name: Aluminium Windows
Definition: A window constructed with a frame made from aluminum alloy building profiles, featuring a hinged sash structure.
Development History:
In the late 1980s, aluminum alloy profiles began replacing steel in window production. While this addressed some of the limitations of steel windows, aluminum itself is highly conductive, leading to rapid heat exchange. This resulted in a U-value (K value) for both steel and aluminum windows exceeding 6.0 W/(m²·K), with no effective solutions for sealing or thermal insulation. Even when paired with insulated glass, the U-value could only drop to around 4.5 W/(m²·K).
By the mid-to-late 1990s, the market saw the introduction of thermal break aluminum insulated windows—high-end products offering enhanced thermal efficiency. These windows incorporated high-strength, insulating composite materials within their profiles, with finishes such as powder coating, fluorocarbon spraying, and resin hot stamping providing diverse color options. Their standout features include lightweight construction, superior strength, excellent water and air tightness, fire resistance, ample natural light, resistance to atmospheric corrosion, long lifespan, aesthetic appeal, and eco-friendly qualities.
However, as living standards improved, people began placing greater emphasis on health, sustainability, and energy efficiency. Traditional insulated aluminum windows and PVC windows struggled to meet modern interior design preferences while failing to align with national energy-saving goals. Additionally, these windows sometimes fell short of satisfying contemporary aesthetic demands.
