Product Description

Energy Star Certified Aluminum Windows

I. Core Features of Aluminum Alloy Windows

Ultra-Low Air Leakage

NFRC (National Fenestration Rating Council) certified air leakage rate ≤ 0.3 CFM/ft² (0.3 cubic feet per minute per square foot), over 70% lower than standard windows (typically >1.0 CFM/ft²), significantly reducing cold drafts in winter and hot air intrusion in summer.

Excellent Thermal Insulation

U-Value (Thermal Conductivity): Certified windows have a U-Value range of 0.20-0.30 W/(m²·K), significantly lower than standard aluminum alloy windows (approximately 5.0 W/(m²·K)) and approaching the level of wooden windows (0.15-0.25 W/(m²·K)).

Insulated Bridge Structure: Built-in PA66+GF25 insulation strips eliminate thermal bridges between the aluminum frame and the window, keeping the window frame surface temperature within 3°C of the indoor temperature, eliminating the risk of condensation.

High Solar Control Capability

SHGC (Solar Heat Gain Coefficient): Optimized based on climate zoning, SHGC ≥ 0.4 in cold regions (maximizing passive solar warming) and SHGC ≤ 0.25 in hot regions (reducing air conditioning load).

Low-E Coating: Blocks 80%-90% of infrared rays (wavelength 780-2500nm) while maintaining 70%-85% visible light transmittance, achieving "light-transmitting, heat-repellent" performance.

II. Energy-Efficient Aluminum Sliding Windows Material Characteristics

Aluminum Alloy Base

6063-T5 Alloy: Tensile strength ≥ 160MPa, yield strength ≥ 110MPa, elongation ≥ 8%, meeting high wind pressure (e.g., level 9 wind pressure ≥ 2.5kPa) and seismic design requirements.

Surface Treatment: AkzoNobel powder coating (film thickness 60-80μm) or anodizing (AA15 grade), salt spray corrosion resistance ≥ 1000 hours, service life exceeding 30 years.

Glazing System

Double-glazed insulating glass: Standard configuration: 5mm + 12mm argon barrier + 5mm, K value ≤ 2.0 W/(m²·K); optional triple-glazed, double-chambered (5mm + 12A + 5mm + 12A + 5mm, K value ≤ 1.2 W/(m²·K)).

Laminated glass: 6mm + 1.52mm PVB + 6mm structure, with an impact strength of 5kJ/m² (compliant with EN12600 1B1), suitable for high-rise buildings or hurricane-resistant areas.

Sealing System

EPDM sealing strips: Weather-resistant from -40°C to +80°C, compression set ≤ 25%, service life ≥ 15 years.

Multi-layer sealing design: The inner and outer frame overlaps utilize three layers of sealing (airtight strip, watertight strip, and dustproof strip), achieving a watertightness of 600Pa (equivalent to heavy rain-level waterproofing).

III. Advantages of Custom Aluminum Windows

Climate Adaptability

Cold Regions: Choose a high SHGC (≥0.4) with a triple-glazed, double-chamber structure to harness solar heat and reduce heating energy consumption (measured reductions of 15%-20%).

Hot Regions: Choose a low SHGC (≤0.25) with a heat-reflective coating to block solar radiation and reduce air conditioning loads by 25%-30%.

Dimensional Flexibility

Customizable (minimum 300mm x 300mm, maximum 6m x 3m). A single sash can withstand up to 150kg, making it suitable for large-span curtain walls or corner windows.

Low Maintenance Cost

Aluminum alloy is corrosion-resistant and age-resistant, requiring no regular painting and maintenance like wooden windows. The self-cleaning glass coating reduces cleaning frequency by 50%.

IV. Application Scenarios for Aluminum Windows

Residential Sector

Passive Houses: Combined with a fresh air system and ground-source heat pump, achieve annual energy consumption of less than 15kWh/(m²·a) (in compliance with PHPP standards). Zero-Carbon Buildings: High thermal insulation (U-value ≤ 0.8 W/(m²·K)) integrated with photovoltaic glass achieves energy self-sufficiency.

Commercial Buildings

Super-High-Rise Curtain Walls: Wind pressure resistance reaches Level 9, capable of withstanding wind speeds of 300 km/h (equivalent to a Level 17 typhoon).

Data Centers: Airtightness rating 8 (NFRC standard) is adopted to prevent dust intrusion and ensure stable equipment operation.

Public Facilities

Schools and Hospitals: Laminated glass and multi-point locking systems are used, achieving impact resistance of EN12600 1B1, meeting safety regulations.

Museums and Archives: Low-E glass with a UV blocking rate of ≥ 99% is selected to protect exhibits from UV damage.
