Aluminum double hung windows feature two operable sashes that slide vertically, allowing flexible ventilation from the top or bottom. Built with durable aluminum profiles, they provide excellent weather resistance, smooth operation, and a clean, modern appearance suitable for residential and commercial buildings. series: 72 series thermal break opening style: Double Hung and Inward Tilt Glass: 5mm+9A+5mm clear tempered glass Color: white Certification: NFRC, AAMA, CE, TITLE 24, AS2047 U-Factor  ≤ 0.3 SHGC ≤ 0.23

An aluminum double hung window offers classic functionality combined with modern material strength. The balanced sash system ensures easy opening and closing, while aluminum frames deliver long-term durability and low maintenance. This window type is ideal for projects requiring ventilation control and a timeless design. series: 83 series thermal break opening style: Double Hung and Inward Tilt Glass: 5mm+9A+5mm clear tempered glass Color: white Certification: NFRC, AAMA, CE, TITLE 24, AS2047 U-Factor  ≤ 0.3 SHGC ≤ 0.23

Designed for practicality and performance, aluminum double hung windows allow efficient airflow without protruding outward. The strong aluminum construction resists corrosion and deformation, making it suitable for various climates. With optional insulated glazing, these windows also contribute to improved thermal and acoustic performance. series: 83 series thermal break opening style: Double Hung and Inward Tilt Glass: 5mm+9A+5mm clear tempered glass Color: white Certification: NFRC, AAMA, CE, TITLE 24, AS2047 U-Factor  ≤ 0.3 SHGC ≤ 0.23

Aluminum double hung windows provide versatile ventilation and user-friendly operation through independently movable sashes. Their slim aluminum profiles maximize glass area for better daylight while maintaining structural stability. Widely used in apartments, offices, and hotels, they blend functionality with contemporary aesthetics. series: 83 series thermal break opening style: Double Hung and Inward Tilt Glass: 5mm+9A+5mm clear tempered glass Color: white Certification: NFRC, AAMA, CE, TITLE 24, AS2047 U-Factor  ≤ 0.3 SHGC ≤ 0.23

Combining traditional window style with modern engineering, aluminum double hung windows deliver reliable performance and durability. The aluminum frame ensures strength and longevity, while the vertical sliding design saves space and enhances safety. They are an excellent choice for both renovation and new construction projects. series: 83 series thermal break opening style: Double Hung and Inward Tilt Glass: 5mm+9A+5mm clear tempered glass Color: white Certification: NFRC, AAMA, CE, TITLE 24, AS2047 U-Factor  ≤ 0.3 SHGC ≤ 0.23

Aluminum outward opening casement window with black colour. Customized RAL colour is available With thermal break good insulation. With stainless screen inward opening Double glass good energy saving and  Noise proof Multi-locking point system 

Aluminum fixed windows are designed to provide maximum daylight and unobstructed views. Built with high-strength aluminum profiles, they offer excellent structural stability and long-term durability. As non-opening windows, they deliver superior air and water tightness, making them ideal for facades, curtain walls, and feature windows in modern buildings. series: 55 series thermal break opening style: non opening Glass: 5mm+9A+5mm clear tempered glass Certification: NFRC, AAMA, CE, TITLE 24, AS2047 U-Factor  ≤ 0.3 SHGC ≤ 0.23

Aluminum double hung windows are designed with two vertically sliding sashes for flexible and convenient ventilation. The strong aluminum frame ensures long-lasting durability, resistance to corrosion, and stable performance, making them suitable for both residential and commercial applications. series: 83 series thermal break opening style: Double Hung and Inward Tilt Glass: 5mm+9A+5mm clear tempered glass Color: white Certification: NFRC, AAMA, CE, TITLE 24, AS2047 U-Factor  ≤ 0.3 SHGC ≤ 0.23

The main body of the heat-insulating aluminum alloy is made of aluminum, and a plastic profile cavity is used as the heat-insulating material in the middle of the profile. This innovative structural design takes into account the advantages of plastic and aluminum alloy materials, while meeting various requirements for decorative effect, strength and aging resistance of doors and windows. The thermally insulated broken bridge aluminum-plastic profile can realize the three-way sealing structure of doors and windows, reasonably separate the water vapor cavity, successfully achieve equal pressure balance of air and water, and significantly improve the water and air tightness of doors and windows. The air tightness of insulated aluminum doors and windows is better than that of any aluminum or plastic windows. It can ensure that indoor window sills and floors in areas with strong wind and sand are dust-free; it can ensure that residents 50 meters on both sides of the highway are not disturbed by noise; and the thermal conductivity is better than Non-insulated aluminum alloy doors and windows reduce the cost by 40 to 70%.
