Product Description

Energy Efficient Aluminum Casement Windows are modern building door and window products that combine aluminum alloy profiles with high-performance glass systems. They achieve high efficiency and energy saving through thermal insulation technology, low-radiation coated glass (Low-E glass) and multi-layer hollow structures. Its core application scenarios include high-end residences, commercial buildings, public facilities and passive houses.

Aluminum Alloy Windows Core Application Scenarios

High-end residences and villas

In tropical or temperate climate zones, energy-saving aluminum casement windows reduce indoor air conditioning energy consumption through thermal insulation thermal insulation design. For example, casement windows with 6mm+12A+6mm hollow glass can have a U value as low as 0.24 W/(m²·K), which is more than 60% energy-saving than ordinary single-layer glass windows.

Commercial buildings and office buildings

Large-size (such as 1500mm×3500mm) casement window design meets the lighting needs of commercial spaces, while controlling the solar heat gain coefficient (SHGC) through Low-E glass to reduce summer cooling loads. For example, a project uses a glass configuration with SHGC 0.14, which reduces annual air conditioning energy consumption by about 25%.

Public facilities and schools

The sound insulation performance (≤41dB) and wind pressure resistance (≥4500Pa) make it suitable for noise-sensitive areas such as airports and schools. For example, casement windows with laminated glass can effectively block traffic noise while meeting typhoon resistance design standards.

Passive houses and zero-energy buildings

Through three-glass two-cavity (6+9A+6+9A+6mm) glass, warm edge spacers and multi-locking point sealing systems, air tightness ≤0.3m³/(m·h) is achieved, which meets the passive house certification requirements. For example, a passive house project reduces annual heating energy consumption to 15kWh/(m²·a) through this configuration.

Key Technical Parameters and Performance Advantages

Thermal Insulation

The thermal conductivity coefficient (K value) of the broken bridge aluminum profile with PA66 nylon insulation strip is ≤2.0W/(m²·K), which is more than 50% lower than that of ordinary aluminum alloy windows. For example, the measured U value of a casement window with a 1.4mm profile and a depth of 55mm of a certain brand is 0.28 W/(m²·K).

Optical Performance

The light transmittance of Low-E glass is 70%-85%, and it reflects more than 80% of infrared rays. For example, a project uses double silver Low-E glass, which increases the indoor temperature by 3-5℃ in winter and reduces it by 2-4℃ in summer.

Sealing and Durability

Multiple EPDM sealing strips are combined with a hidden drainage design, with air tightness reaching national standard level 8 and water tightness ≥600Pa. For example, a coastal project passed the salt spray test (≥1000 hours) and the profile surface was corrosion-free.

Safety and anti-theft

German ROTO or Chinese Jianlang hardware is standard, and the multi-locking point actuator can withstand external forces of more than 1000N. For example, the bank project uses C-level anti-theft lock points and has passed EN 1627 RC3 certification.

Aluminum Windows Procurement Adaptability Analysis

Cost-effectiveness

The unit price range is 40-200/m², and bulk purchases (≥100m²) can enjoy discounts. For example, the developer purchases 500m² of broken bridge casement windows, and the unit price drops from 120 to 96/m², reducing the overall cost by 12%.

Customized service

Supports RAL color card customization, special-shaped window design and smart lock integration. For example, the hotel project pre-installs the window type through the BIM model to achieve seamless connection with the curtain wall system, shortening the construction period by 15 days.

Certification and warranty

Mainstream products are certified by AS2047 (Australia), NFRC (North America), and CE (EU), providing 5-10 years of material warranty and lifetime maintenance.

Supply chain stability

The annual production capacity of Chinese manufacturers reaches 100,000 m², with a delivery time of 15-38 days.

Custom Aluminum Windows Purchasing Recommendations

Budget-limited projects: Choose 1.4mm profile + double-layer insulating glass configuration, unit price 40-60/m², to meet basic energy-saving needs.

High-end customized projects: Use 2.0mm profile + three-glass two-chamber Low-E glass, unit price 120-200/m², adapted to passive house standards.

Long-term cooperation: Prioritize factories that have passed ISO 9001 certification to ensure that the profile wall thickness tolerance is ≤±0.1mm and the glass hollow layer thickness error is ≤±1mm.
