Product Overview


The GR78XL Energy Efficient Industrial Style Eco Friendly Casement Windows stand at the intersection of rugged industrial design and advanced environmental technology. More than just functional fixtures, they serve as statement pieces for commercial spaces like art galleries and co-working hubs, as well as residential properties such as converted warehouses and modern minimalist homes. The windows boast a monochromatic color scheme—with options including matte black, charcoal gray, and brushed silver—and exposed aluminum frames that highlight raw material texture, embodying the industrial aesthetic. Underpinning their visual appeal is a robust energy-saving system: double-glazed Low-E glass with a microscopically thin metallic coating reflects infrared radiation, while PA66 GF25 thermal breaks—reinforced with 25% glass fiber for enhanced strength—create a thermal barrier that minimizes heat transfer. This combination delivers A++ energy efficiency, slashing carbon emissions by up to 35% compared to standard windows, making them a top choice for eco-conscious architects and homeowners.


Product Characteristics


Frame Material: Anodized Aluminum Alloy with PA66 GF25 Thermal Break (1.4mm wall thickness for structural integrity)

Glass Type: Double Glazed Low-E Glass (5mm + 20mm Air Gap + 5mm) with argon gas filling for improved insulation

Energy Efficiency Rating: A++ (U-Factor: 1.5 W/(m²·K))—certified by international energy efficiency bodies

Sound Reduction: 38dB—equivalent to reducing street noise from busy traffic to a quiet conversation level

Wind Resistance: Class 9 (≥5.0kPa)—capable of withstanding strong gusts in urban high-rises

Certifications: Energy Star Certified, along with ISO 14001 for environmental management


Advantages


Industrial Design Meets Sustainability

The exposed aluminum frame isn’t just a design choice—it’s a testament to durability, resisting warping and fading even after decades of exposure to sunlight and moisture. The monochromatic finish undergoes a 10-stage anodization process, ensuring scratch resistance and color retention. What’s more, the frames are crafted from 85% recycled aluminum alloy, with 100% recyclability at the end of their lifespan, aligning with circular economy principles.


Energy Efficiency

The synergy between double-glazed Low-E glass and PA66 thermal breaks delivers tangible savings. The Low-E coating blocks 70% of infrared heat in summer while retaining indoor warmth in winter, and the thermal breaks reduce heat conduction by 60% compared to non-insulated frames. This translates to a 40% reduction in heating and cooling costs—equivalent to saving 300-500 annually for an average 1,500 sq ft home—while maintaining consistent indoor temperatures.


Durability & Low Maintenance

The anodized aluminum frame is corrosion-resistant, eliminating the need for repainting or refinishing over its 30+ year lifespan. A multi-point locking system—with 4-6 locking points depending on window size—enhances security, while friction hinges allow smooth operation with minimal wear. The glass is treated with a hydrophobic coating that repels water and dust, reducing cleaning frequency by half.
