Top-Tier Aluminum-Plastic Co-Extrusion Window System | Uw≤1.2 | Perfect for Energy-Efficient Homes

The 75-90 series fully clad aluminum-plastic co-extruded window represents the pinnacle of modern window engineering, combining cutting-edge technology with timeless design to deliver an unparalleled living experience. Olis Metal, with over a decade of expertise in manufacturing high-performance architectural products, is proud to introduce this revolutionary integrated window system that sets new standards for energy efficiency, durability, and aesthetic appeal. Specifically engineered to meet the most demanding requirements of contemporary construction, this aluminum-plastic co-extruded window is the perfect choice for discerning homeowners, architects, and builders who refuse to compromise on quality.

At the heart of our 75-90 series aluminum-plastic co-extruded window lies our proprietary fully clad co-extrusion technology, a manufacturing process that seamlessly fuses high-strength national standard T66 grade primary aluminum with a 4mm nano-micro-foam thermal insulation layer. This innovative one-piece molding process creates a monolithic structure that eliminates the risk of delamination, ensuring exceptional structural integrity and long-term performance. The internal aluminum skeleton provides unmatched rigidity and resistance to deformation, while the outer PVC cladding delivers superior thermal insulation and corrosion resistance. Unlike traditional composite windows that use separate components bonded together, our fully clad design ensures that the insulation layer is completely encapsulated within the aluminum frame, providing consistent thermal performance throughout the entire lifespan of the window.

When it comes to thermal insulation and energy efficiency, our 75-90 series fully clad aluminum-plastic co-extruded window delivers truly exceptional results. With an outstanding thermal transmittance value of Uw≤1.2 W/m²·k, this window meets and exceeds the strictest international energy efficiency standards, making it ideal for low-energy buildings and nearly compliant with passive house requirements . The 40mm triple-pane insulated glass structure, combined with national standard PA66 nylon thermal break strips and automotive-grade EPDM foam composite seals, creates an impenetrable barrier against heat transfer. During the sweltering summer months, it effectively blocks up to 90% of solar heat gain, keeping your home cool and comfortable without overworking your air conditioning system. In the cold winter, it prevents precious indoor heat from escaping, reducing your heating bills by up to 30% compared to standard double-glazed windows . For passive house builders and energy-conscious homeowners, this level of thermal performance means you can achieve significant energy savings while maintaining a consistently comfortable indoor temperature year-round.

Sound insulation is another area where our 75-90 series aluminum-plastic co-extruded window truly shines. With a sound insulation rating of 35≤RW+CU<40 dB (detection level 7), this window effectively blocks out most common urban noises, transforming your home into a peaceful sanctuary away from the hustle and bustle of city life. The triple-glass structure with warm edge spacers, combined with multiple layers of airtight sealing, absorbs and dissipates sound waves before they can enter your home. Whether it’s the honking of cars on busy streets, the chatter of neighbors, or the noise from nearby construction sites, all unwanted sounds are significantly reduced, allowing you to enjoy quiet conversations, restful sleep, and uninterrupted work. For families with young children, remote workers, or anyone who values peace and quiet, this exceptional sound insulation performance is truly life-changing.

Our 75-90 series fully clad aluminum-plastic co-extruded window is engineered to withstand the harshest weather conditions nature can throw at it. With an impressive wind load resistance rating of P2≥5.0 kPa (detection level 9), this window can withstand wind speeds of over 89 m/s, which is more than three times the wind speed of a 12-level typhoon . The high-strength aluminum frame, reinforced with internal steel supports, provides exceptional structural stability, ensuring the window remains firmly in place even during the most severe storms. Additionally, the integrated drainage system and multi-stage sealing structure deliver outstanding rainwater penetration resistance of P≥700 Pa (detection level 7), effectively preventing water from entering your home even during torrential downpours. Whether you live in a coastal area prone to hurricanes, a region with heavy rainfall, or a location with extreme temperature variations, our 75-90 series window will protect your home and family for decades to come.

The 75-90 series aluminum-plastic co-extruded window offers two versatile opening modes—casement and tilt-and-turn—designed to meet the diverse needs of modern living. In casement mode, the window opens fully outward, providing maximum ventilation and unobstructed views. This mode is perfect for warm summer days when you want to let in plenty of fresh air and natural light. The tilt-and-turn mode, on the other hand, allows the window to tilt inward from the top, providing controlled ventilation while preventing rainwater from entering your home. This mode is ideal for rainy days, nighttime ventilation, or when you want to let in fresh air without compromising security. The tilt-and-turn design also eliminates the risk of children climbing out of windows, giving you peace of mind while keeping your home well-ventilated. With these two opening modes, you have complete control over your indoor environment, ensuring optimal comfort in any weather condition.

In addition to its exceptional performance, our 75-90 series fully clad aluminum-plastic co-extruded window features a stunning design that will elevate the aesthetic of any home. The sleek, modern profile with rounded corner (R-angle) protection not only adds a touch of elegance but also improves safety by eliminating sharp edges. We offer a wide range of premium finishes to suit any architectural style and personal taste. For the interior, you can choose between beautiful oak and grey teak wood-grain finishes that perfectly replicate the natural texture and warmth of real wood. For the exterior, we offer durable grey and coffee finishes that are resistant to fading, chalking, and corrosion. All our finishes are applied using advanced powder coating technology, ensuring they retain their vibrant color and beautiful appearance for decades without fading or peeling.

We understand that even the best window design is only as good as its hardware, which is why we equip every 75-90 series aluminum-plastic co-extruded window with premium Kin Long hardware. Kin Long is a world-renowned manufacturer of high-quality window and door hardware, known for its exceptional durability, smooth operation, and innovative design.
