Aluminum Double Hung Double Tilt Window

We designed our Aluminum Double Hung Double Tilt Window to offer B2B distributors and historic renovation contractors a premium, low-maintenance vertical sliding solution that combines classic styling with advanced thermal performance. Operating from our modern 30,000-square-meter facility, we use high-tensile 6063-T5 extruded aluminum profiles that provide superior structural strength compared to standard vinyl or wood frames. In traditional urban residential projects and historic renovations, windows are highly scrutinized for their ease of maintenance and resistance to structural warping. Our Aluminum Double Hung Double Tilt Window features two independent sliding sashes that both tilt inward for easy, safe cleaning of the exterior glass surfaces from inside the building. The frame is reinforced with heavy-duty constant-force spring balances that allow both sashes to slide smoothly and hold their position indefinitely, ensuring smooth operation. Our commitment to quality has helped us become a leading brand in the custom home furnishing market.

We understand that project managers and builders require window systems that can be installed quickly and perform reliably with minimal maintenance. The frames of our Aluminum Double Hung Double Tilt Window are assembled using our German-imported precision double-head cutting saws and automatic corner crimping machines, ensuring perfect structural alignment. Each window is fitted with high-density EPDM dual-weather stripping gaskets and multi-point lock systems that seal the sashes tightly against wind and rain, helping developers meet strict building energy codes. Our factory has invested over 41 million RMB in high-performance CNC equipment and testing platforms to ensure every unit meets precise specifications. As an ISO9001-certified manufacturer, we conduct a 100% pre-packing inspection on every single window, checking the tilt mechanism, balance tension, and lock alignment. This strict quality control ensures your installation team can work efficiently on-site, saving labor costs and preventing costly callbacks.

Perfect for historic townhomes, urban apartment buildings, school facilities, and high-end residential renovations where traditional vertical sliding aesthetics and easy indoor cleaning are required.

We specialize in custom manufacturing tailored to your exact architectural drawings and specifications. We can customize the frame dimensions, grid patterns (muntins), glass types (laminated, tinted, or double low-E), and frame colors. Our engineering team can develop custom samples in 15 to 20 working days, and we provide free sample profiles to qualified commercial buyers for project approvals.

Every window undergoes a rigorous 100% manual and mechanical inspection before it is packed and shipped. Our production complies with local environmental regulations and holds European E0-class certification. In the event of transit damage, we follow our clear service protocol: immediate responsibility determination, on-site assessment, and rapid replacement or credit adjustment.
