GR70XL
SUNGYE
The GR70XL Maximize Natural Light Insulated Large Format Casement Windows are engineered for luxury homes, high-end villas, and premium commercial spaces where unobstructed views and energy efficiency are paramount. Constructed with heavy-duty 6063-T5 aluminum frames (2.0mm wall thickness) and PA66 GF25 thermal breaks, these windows achieve A+++ energy efficiency (U-Factor: 0.9 W/(m²·K))—meeting passive house standards. The large-format glass panels (up to 2.5m x 2m) maximize natural light intake while delivering 40dB noise reduction, creating serene interiors even in busy areas. Equipped with multi-point locking systems (5 locking points) and smart home integration (Alexa/Google Home compatibility), they blend grand aesthetics with advanced functionality.
Frame Material: 6063-T5 Aluminum Alloy with PA66 GF25 Thermal Break (multi-chambered for insulation)
Glass Type: Triple Glazed Low-E with Argon Gas (5mm + 12mm Argon + 5mm + 12mm Argon + 5mm)
Energy Efficiency: A+++ (U-Factor: 0.9 W/(m²·K))—PHI Passive House certified
Wind Resistance: Class 9 (≥5.0kPa)—stable in extreme wind conditions
Sound Reduction: 40dB (reduces 75dB highway noise to 35dB whisper-quiet levels)
Certifications: Energy Star, PHI Passive House Certified
The triple-glazed Low-E glass blocks 99% of UV rays and reflects 90% of solar heat, reducing heating and cooling costs by 40% annually. The PA66 GF25 thermal break minimizes heat loss by 70%, maintaining consistent indoor temperatures without excessive HVAC use.
The multi-chambered frame design and stainless steel hinges support glass weights up to 200kg, ensuring stability for large-format panels. EN 356 Class P8B-rated impact-resistant laminated glass withstands forced entry attempts and extreme weather events.
Bluetooth-enabled locks allow remote operation via smartphone apps, while built-in weather sensors automatically close windows during rainstorms. The smart ventilation system adjusts opening angles based on indoor CO₂ levels (triggered at 1,000ppm), optimizing air quality without energy waste.
Sustainability: 90% recycled aluminum used in production, with a carbon-neutral manufacturing process certified by ISO 14064.
Installation: Expert teams use crane-assisted placement for large panels, with laser alignment ensuring airtight seals and structural safety.
Warranty: 15-year guarantee on hardware (locks, hinges, sensors) and 25-year coverage on glass units, including seal failure and smart system functionality.
What are the size and weight limits for the GR70XL casement windows?
The GR70XL supports an open fan width of 450mm to 850mm and heights starting from 1450mm, with a maximum sash weight of 70kg. This allows for large-format designs while maintaining smooth, reliable operation.
What materials and glass configuration are used for energy efficiency?
The frame uses 1.8mm wall thickness aluminum, with a 60.5mm frame width and 80mm sash width. The windows feature 5G+18A+5G insulated glass, delivering a U-factor of 0.26, solar heat gain coefficient of 0.32, and visible transmittance of 0.53 for excellent thermal and daylight performance.
How do the GR70XL windows perform in terms of air, condensation, and durability?
Sungye hardware ensures durability, while the design achieves condensation resistance of 70 and air infiltration of 0.012 cfm/ft², providing airtight sealing, reduced drafts, and long-term comfort in various climates.

Here's a structured breakdown of Sungye GR70XL Aluminum Casement Windows with key selling points and detailed explanations:
Robust aerospace-grade alloy ensures structural integrity for high-rise installations.
The GR70XL uses 6063-T6 aluminum, heat-treated for enhanced tensile strength (≥245 MPa) and corrosion resistance. Its reinforced corners and 2.5mm wall thickness withstand wind loads up to 3,500 Pa, ideal for coastal or extreme climates. Precision-milled grooves ensure seamless hardware integration, while anodized/powder-coated finishes prevent UV degradation.
Multi-chamber design with TPE insulation achieves U-value ≤1.2 W/m²K.
Featuring a 34mm thermal barrier and dual TPE (Thermoplastic Elastomer) seals, the GR70XL minimizes heat transfer. Independent testing confirms condensation resistance at -30°C and thermal stability up to 80°C. The staggered chamber layout disrupts thermal bridging, reducing HVAC costs by ~25% in energy-efficient buildings.
Integrated 8-point locking meets BS PAS 24:2016 anti-burglary standards.
Stainless steel shoot bolts engage simultaneously into reinforced strike plates, resisting 2,500N of force. Tamper-proof hinge shields and interlocking sash-frame geometry block crowbar attacks. Optional smart locks with IP66-rated sensors enable remote monitoring, aligning with commercial security protocols.
Laminated glass + dual-seal design cuts urban noise by 80%.
The GR70XL pairs 6mm laminated glass (PVB interlayer) with asymmetric EPDM gaskets, achieving Rw 45dB sound reduction. Frequency-specific damping neutralizes traffic/aircraft noise (tested per EN ISO 10140). Optional argon-filled triple glazing boosts Rw to 50dB for hospitals or studios.
40+ RAL colors, dual-tone finishes, and modular glazing bars.
Architects can specify interior/exterior color combinations (e.g., woodgrain inside, metallic outside) for biophilic design. Slim 70mm sightlines maximize views, while optional lead-free faux muntins replicate historic styles. Pre-engineered CAD templates ensure quick adaptation to curved or angled openings.
100% recyclable materials + ISO 14025-compliant lifecycle assessment.
Sungye’s closed-loop production reclaims 98% of aluminum scrap. Low-VOC powder coatings and GREENGUARD Gold certification ensure indoor air safety. The GR70XL exceeds EN 14001 standards, with a 50-year lifespan and 90% post-consumer recyclability, reducing embodied carbon by 40% vs. conventional frames.
Self-cleaning Nano-X coating repels dust, rain, and salt deposits.
The hydrophobic outer layer uses photocatalysis to break down organic debris, requiring only annual rinsing. Stainless steel hardware resizes friction-free for 20+ years. Pre-lubricated rollers and adjustable hinges enable DIY alignment without disassembly.
Each feature is engineered to address architectural, environmental, and user-centric demands, positioning the GR70XL as a premium solution for residential and commercial projects.
