Report from Correspondent Greborn, a high-end window and door brand originating from Northeast China, has emerged as a preferred solution for extreme cold regions such as North America and Northern Europe, thanks to its core technologies developed specifically for frigid environments. With a focus on 6060-T66 European standard high-precision aluminum profiles and patented multi-cavity energy-saving sealing systems, its products exhibit remarkable durability, cold resistance, and thermal insulation at -30°C. They have successfully passed international authoritative certifications such as Australian AS2047 and US NFRC.

Greborn's competitive advantage is a result of years of development in the bitterly cold climate of Northeast China. The 6060-T66 profiles combine low-temperature brittleness resistance with high wind pressure resistance. They achieve a thermal conductivity (U-value) as low as 1.4W/(㎡¹K) thanks to triple-insulated glass and adhesive injection sealing systems, which improves thermal insulation by more than 30% when compared to traditional windows and doors. This can lower users' heating energy consumption by more than 15% and raise indoor temperatures by 3–5°C. Products with optimized low-temperature sealing are designed for the cold and snowy conditions of North America, while those with improved anti-aging and heat insulation designs are ideal for Australia's harsh cold and intense UV radiation.

Globalization is made possible by international certifications. NFRC-certified products meet North American passive house standards, while AS2047 certification ensures structural safety in alternating strong winds and freezing temperatures. The simultaneous operation of US and Australian branches in 2025 has realized a "Made in China + localized service" model. Digital factories shorten custom delivery cycles to 15 days, and modular quick-install structures boost installation efficiency by 60%, enabling rapid responses to overseas market demands.

Currently, Greborn’s products cover cold regions across North America, Europe, and Australia, applied in high-end residences, commercial complexes, and other scenarios. The triple benefits of "cold resistance toughness + green energy efficiency + intelligent adaptability" have made it a standard option for window and door upgrades in cold-climate regions of the world. In the future, the company plans to expand into European and Canadian markets, optimize technologies for extreme cold adaptation, and maintain its R&D base in Northeast China.
