The green energy efficiency of aluminum alloy doors and windows has emerged as a crucial criterion for access to international markets in light of the growing global carbon neutrality strategy. Continuously updated standards like the US ENERGY STAR, German PHI Passive House, and EU CE certification place strict requirements on indicators like the carbon footprint, recycled material utilization rate, and thermal transmittance (U-value) of doors and windows. Through technological innovation and precise alignment with global trends, Greborn Windows & Doors has become a benchmark brand in the green and energy-efficient door and window industry.

Profiles made of more than 75% recycled aluminum surpass the widely accepted international standard of 50% recycling ratio, and Greborn's core products have whole-life carbon emissions that are 45% lower than those of conventional products, meeting the highest international standards. By combining vacuum Low-E glass with multi-chamber thermal insulation strips, the U-value (thermal transmittance) is lowered to 0.72 W/(m²·K), surpassing the EU EN 14351-1 standard's 1.4 W/(m²·K) limit and satisfying the highest German PHI-B Passive House certification level. The products, meanwhile, have Class 6 airtight structures and bio-based sealing systems, with VOC emissions ≤0.05mg/m³, passing the French A+ and US GREENGUARD environmental certifications to totally prevent the release of hazardous materials.

Greborn has achieved closed-loop control from raw materials to recycling by utilizing a full-process green production system. The production process uses a photovoltaic power supply and zero wastewater discharge technology, which has a 99% dust collection efficiency. The profiles have a detachable design and a recycling rate of over 95%, which fully complies with the Carbon Border Adjustment Mechanism (CBAM) and EU ESPR regulation's carbon footprint accounting requirements. Greborn Windows & Doors is now a strategic bulk procurement product for numerous international real estate companies, having successfully entered European passive house communities and North American green building projects with its triple international certifications of CE, PHI-B, and ENERGY STAR.
