Single-Hung Windows
SUNGYE
The Stylish Durable Energy Efficient Aluminum Single Hung Windows blend contemporary design with high-performance engineering to elevate modern home aesthetics and comfort. Ideal for bedrooms, kitchens, and living rooms, these windows feature a slim-profile aluminum frame (1.4mm wall thickness) that maximizes glass area by 15% compared to bulkier designs, paired with a PA66 GF25 thermal break for superior insulation. This combination achieves A++ energy efficiency (U-Factor: 1.3 W/(m²·K))—one of the highest ratings for single hung windows. The single-hung sash slides vertically on precision tracks for controlled ventilation, while the self-cleaning Low-E glass (coated with titanium dioxide) uses sunlight and rain to break down dirt particles, reducing cleaning frequency by 60%. Available in 12 RAL colors (including popular options like RAL 9005 Jet Black and RAL 7016 Anthracite Gray), these windows complement minimalist, industrial, or Scandinavian-inspired interiors.
Frame Material:The window frame is made of anodized aluminum alloy with a PA66 GF25 thermal break. Its corrosion-resistant finish ensures long-lasting durability and stable structural performance.
Glass Type:It features double-glazed Low-E self-cleaning glass with a 5 mm + 16 mm argon-filled + 5 mm configuration. This design improves insulation and reduces maintenance needs.
Energy Efficiency:The window achieves an A++ rating with a U-factor of 1.3 W/(m²·K). NFRC certification confirms reliable thermal performance and reduced energy consumption.
Wind Resistance:Class 8 wind resistance withstands pressures ≥4.0 kPa. The design is stable in moderate wind conditions, suitable for mid-rise residential or commercial buildings.
Sound Reduction:The window reduces noise by 38 dB, lowering highway or street sounds from 76 dB to approximately 38 dB, creating a comfortable indoor environment.
Certifications:The product is NFRC certified, meets ISO 14001 environmental standards, and complies with AAMA 2604 coating requirements, ensuring quality, sustainability, and exterior durability.
The self-cleaning glass eliminates the need for harsh cleaning chemicals: its photocatalytic coating reacts with sunlight to break down organic dirt, while hydrophilic properties cause rainwater to sheet off, leaving glass streak-free. The anodized finish forms a protective oxide layer that resists scratches, fading, and corrosion, requiring only occasional wiping with a damp cloth to maintain its appearance.
The PA66 thermal break creates a barrier that minimizes heat transfer, keeping interiors ±2°C of the desired temperature year-round. The double-sealed weatherstripping (EPDM rubber) blocks drafts and dust infiltration, improving airtightness by 80% compared to standard windows—reducing allergies and energy waste.
The child-resistant lock restricts sash movement to 10cm, preventing accidental falls while still allowing ventilation. The tempered glass undergoes heat treatment to withstand impacts up to 900N (equivalent to a 90kg force), exceeding EN 12600 Class 1B1 standards for impact resistance.
Customization: Opt for tilt-in sashes for easy exterior cleaning or decorative grids (colonial, prairie, or custom patterns) to add architectural detail.
Installation: Post-installation includes free thermal imaging scans to verify insulation performance and identify any air leakage points for immediate correction.
Warranty: 10-year guarantee on hardware (locks, balances, tracks) and 15-year warranty on glass units, covering seal failure, coating degradation, and operational issues.
