What are the features and advantages of aluminum-clad windows and doors?
Release date:
2025-09-01
Aluminum doors and windows with a thermal break, also known as thermally broken aluminum doors and windows or thermally insulated aluminum alloy profiles, offer significantly superior performance compared to standard aluminum alloy profiles. They represent the fifth-generation of innovative, energy-efficient, and heat-insulating window and door systems—evolving beyond traditional wood windows, iron windows, PVC/steel composite doors and windows, and conventional colored aluminum alloy products.
The principle behind thermal-break aluminum alloy involves inserting a thermal break strip into the middle of the aluminum profile, effectively "breaking" the continuous aluminum structure and creating a thermal barrier that significantly inhibits heat transfer. When used for windows and doors, this type of profile meets national energy-saving standards, addressing the critical issue of rapid heat conduction in conventional aluminum alloys—something that previously made them unsuitable for energy-efficient applications.
Thermal-break aluminum alloy windows and doors exhibit 40% to 70% lower thermal conductivity compared to non-thermal-break aluminum models, with measured K-values ranging below 2.23–2.94 W/m²K. This results in remarkable energy savings, drastically reducing heating and cooling costs. Additionally, these windows and doors offer excellent air and water tightness, thanks to their meticulously engineered design and seamless joint construction. Testing has shown they achieve impressive sound insulation levels, blocking noise by 30–40 dB.
1. Broken bridge aluminum offers excellent thermal insulation and air tightness: The plastic component in the aluminum-plastic composite profile has a low thermal conductivity, providing superior heat insulation. Combined with its outstanding air-tightness, even in frigid regions where outdoor temperatures plummet to below freezing, indoor spaces remain comfortably warm—almost like springtime.
2. Broken bridge aluminum offers excellent sound insulation: Its meticulously designed structure ensures tight sealing at the joints, and it features hollow glass units. Test results show its soundproofing performance meets the standard of 30 dB, complying with relevant sound-insulation material regulations.
3. Broken bridge aluminum is resistant to deformation and impact: Thanks to its exterior surface made of aluminum alloy, broken bridge aluminum composite profiles offer significantly stronger impact resistance compared to PVC-U window profiles—and they remain stable and don’t easily warp even after years of use.
4. Broken-bridge aluminum for energy efficiency and environmental protection: The multi-sealed rubber strips or EPDM seals installed at every gap in the broken-bridge aluminum composite windows ensure Class 1 air tightness, maximizing the effectiveness of air conditioning while reducing energy consumption by up to 50%.
5. Broken bridge aluminum windows and doors offer excellent water resistance, fire protection, and anti-theft performance: The design incorporates a rainproof structure that effectively keeps rainwater from entering, ensuring superior water tightness that meets national standards. Additionally, the aluminum alloy material is inherently non-combustible, eliminating the risk of fire hazards in your home. As for anti-theft capabilities, these windows are equipped with high-quality hardware components and advanced decorative locks, making it virtually impossible for burglars to break in.
6. Eliminates maintenance costs: Break-bridge aluminum doors and windows are made from a material that is highly resistant to acid and alkali corrosion. They won’t yellow or fade over long-term use. If the surface gets dirty, simply wipe it clean with water and a mild detergent—restoring its pristine appearance without any hassle. This eliminates ongoing maintenance expenses, making it both convenient and hassle-free.
Aluminum-clad insulated windows and doors are scientifically designed, utilizing energy-efficient profiles that have earned recognition and high praise from authoritative national agencies—perfect for enhancing the aesthetic appeal of any building.
