Double-Hung Windows
SUNGYE
The Energy Efficient Modern Ventilated Design Double Hung Windows combine ventilation flexibility with A++ energy efficiency. Featuring dual sashes that tilt inward for cleaning and slide vertically for airflow, these windows are ideal for hot climates. The triple-glazed Low-E glass (with argon gas filling) and PA66 GF25 thermal breaks reduce heat transfer by 50%, lowering HVAC costs. The Constant Force Stainless Steel Balance System ensures smooth operation, while the BetterVue® Window Screen enhances visibility without compromising insect protection.:
Frame Material:The window frame is made of anodized aluminum alloy with a PA66 GF25 thermal break. This design reduces heat transfer and improves overall insulation performance.
Glass Type:The unit uses triple-glazed Low-E glass with a 5 mm + 12 mm argon + 5 mm configuration. This setup enhances thermal insulation and reduces energy loss.
Energy Efficiency:The window holds an A++ energy rating with a U-factor of 1.2 W/(m²·K), supporting low heat transfer and reducing heating or cooling energy needs.
Ventilation:Dual sash operation allows both sashes to open independently. This provides flexible airflow control while maintaining security and comfort.
Certifications:The window is NFRC certified and Energy Star qualified, confirming compliance with international standards for energy efficiency and performance.
The variable airflow control allows users to optimize ventilation during mild weather, while the Low-E coating blocks 99% of UV rays and reduces solar heat gain by 70% .
The self-cleaning glass (coated with titanium dioxide) repels dirt, reducing cleaning frequency by 60%. The anodized aluminum frame resists corrosion and requires no painting.
Optional Sound Suppression Technology (available as an upgrade) reduces external noise by 50%, ideal for urban environments .
Customization: Tailor glass thickness (4mm–8mm) and hardware finishes (brass, stainless steel) to local climate needs.
Testing: Certified to ASTM E90 standards for air leakage (<0.1 cfm/ft²) and water resistance (Class 6).
Installation: Free on-site consultations to ensure proper airflow and energy performance.
