High-performance OEM/ODM fenestration solutions engineered for severe weather, optimal acoustic isolation, and architectural elegance.
Guangzhou Cresta Door & Window Co., Ltd. — Driving Architectural Innovation through Advanced Manufacturing
Established in 2015, Guangzhou Cresta Door & Window Co., Ltd. operates a state-of-the-art 18,000-square-meter manufacturing facility. Backed by 11 years of industry experience and 7 years of international trade operations, we achieve an annual export turnover of $22 million across Southeast Asia, the Middle East, and Oceania. We mainly supply custom home builders, renovation contractors, and regional wholesalers.
To ensure top-tier craftsmanship, our team of 30 QC inspectors strictly enforces ISO-certified optical surface inspections and weatherproofing seal tests. With a reliable network of 550 upstream suppliers, Cresta excels in tailored solutions such as custom acoustic insulation, motorized insect screens, and slim-frame sliding doors. Supported by an active R&D division of 35 specialized engineers, we released 38 new product series over the past year.
OEM/ODM Technical Partnership Guarantee: We provide full-lifecycle engineering support from preliminary CAD drawing consultation and structural wind-load calculation to custom extrusions, specialized glass coating matching, and final containerized job-site delivery.
The Synthesis of Exterior Weather Resistance, Interior Warmth, and High-Performance Thermal Separation
Aluminum wrapping windows (often referred to as aluminum-clad fenestration or profile-wrapped aluminum frame systems) represent the modern pinnacle of facade technology. By combining precision-extruded 6063-T5/T6 structural aluminum outer shells with advanced thermal barrier cores or hybrid composite substrates, wrapping window systems solve the traditional compromises between exterior longevity and indoor thermal performance.
Utilizing high-density Polyamide (PA66-GF25) thermal strips, our wrapped aluminum systems eliminate cold-bridging, achieving U-factors as low as 0.8 to 1.2 W/m²K, which drastically lowers HVAC energy consumption in high-rise and residential projects.
Wrapped extrusions are coated with fluoropolymer (PVDF) or AkzoNobel electrostatically applied powder finishes, offering salt-spray resistance up to 3,000 hours and UV stabilization against fading, chalking, and severe coastal erosion.
Integrated EPDM multi-seal gaskets combined with double or triple insulated glass units (IGUs) filled with 90% pure Argon gas deliver sound reduction levels up to STC 45 dB, keeping interior spaces completely quiet.
