Superior Low-Energy Aluminum-Plastic Co-Extrusion Casement Window | Wood-Grain Finish | EPDM Seals

The aluminum-plastic co-extrusion casement window from Olis Metal represents a transformative leap forward in modern window technology, engineered to deliver an unprecedented thermal transmittance value of Uw≤1.0 W/m²·k—nearly meeting the rigorous standards of certified passive house construction. This exceptional level of thermal performance places our window among the most energy-efficient glazing solutions available on the market today, making it the ideal choice for discerning homeowners, architects, and developers who demand nothing but the best for their projects. Every aspect of this window has been meticulously designed and crafted to deliver superior performance in every category, from thermal insulation and sound reduction to wind resistance and durability, ensuring that it will provide decades of reliable service and unparalleled comfort.

At the heart of our aluminum-plastic co-extruded casement window lies our revolutionary one-piece co-extrusion manufacturing process, which seamlessly merges high-strength 6063-T5 primary aluminum alloy with a 4mm thick layer of premium rigid micro-foam PVC into a single, monolithic structure. This innovative technique eliminates the common issues of delamination, separation, and thermal bridging that plague traditional composite windows, ensuring exceptional structural integrity and long-lasting performance. The internal aluminum skeleton provides unparalleled rigidity and resistance to warping, bending, and corrosion, while the outer PVC layer delivers outstanding thermal insulation properties—with a thermal conductivity of just 0.17 W/m·K, compared to 160 W/m·K for pure aluminum. This unique hybrid design gives our window the strength and durability of metal combined with the superior insulation of plastic, creating a product that truly stands the test of time.

When it comes to thermal insulation and energy efficiency, our aluminum-plastic co-extrusion casement window truly stands out from the competition with its remarkable Uw≤1.0 W/m²·k rating. This exceptional performance is achieved through a combination of advanced design features, including a multi-chamber frame structure with up to 6 insulated air pockets, high-performance triple-glazed glass with two low-emissivity (Low-E) coatings, argon gas filling between the panes, and warm-edge spacers that minimize thermal bridging at the glass edges. The result is a window that effectively blocks up to 92% of unwanted heat transfer, keeping your home cool and comfortable during the sweltering summer months and warm and cozy during the cold winter season. Independent testing has shown that installing our Uw≤1.0 aluminum-plastic co-extrusion windows can reduce your annual heating and cooling costs by up to 40% compared to standard double-glazed windows, making it an incredibly smart investment that will pay for itself over time through lower energy bills. For passive house builders and energy-conscious homeowners, this level of thermal performance means you can achieve the ultra-low energy consumption targets required by modern green building standards without compromising on comfort or aesthetics.

Living in a noisy urban environment can be incredibly stressful and detrimental to your health and well-being, but our aluminum-plastic co-extruded casement window provides the perfect solution by creating a peaceful sanctuary within your home. With a sound insulation rating of up to 35 dB, this window effectively blocks out most common urban noises, including traffic, construction, neighborhood chatter, and aircraft overhead. The triple-glazed glass structure with laminated inner panes, combined with three layers of automotive-grade EPDM foam composite seals and an airtight frame design, absorbs and dissipates sound waves before they can enter your home. Whether you’re trying to work from home without distractions, get a restful night’s sleep, or simply enjoy a quiet evening with your family, this exceptional sound insulation performance ensures that you can do so without being disturbed by the outside world. Imagine coming home after a long, hectic day and stepping into a space where the noise and chaos of the city fade away—this is the transformative experience our aluminum-plastic co-extrusion casement window delivers.

Our aluminum-plastic co-extrusion casement window is engineered to withstand even the harshest weather conditions, providing reliable protection for your home year-round. With an impressive wind load resistance rating of level 9—the highest national standard—this window can withstand wind speeds of up to 89 m/s (320 km/h), making it ideal for use in high-rise buildings, coastal areas, and regions prone to strong winds, typhoons, and hurricanes. The high-strength aluminum frame, reinforced with internal steel supports, provides exceptional structural stability, ensuring that the window remains firmly in place and operates smoothly even during the most severe storms. Additionally, the integrated drainage system and multi-stage sealing structure deliver outstanding water resistance of level 7, effectively preventing rainwater from entering your home even during torrential downpours and driving rain. You can rest easy knowing that your home is protected against the elements, no matter what Mother Nature throws your way.

The classic casement opening design of our aluminum-plastic co-extruded casement window offers numerous advantages that make it a popular choice for homeowners worldwide. In casement mode, the window opens fully outward, providing maximum ventilation and unobstructed views of the outdoors. This allows fresh air to circulate freely throughout your home, creating a healthy and comfortable living environment. The outward opening design also means that the window does not take up any interior space, making it ideal for use in smaller rooms, kitchens, bathrooms, or areas where space is at a premium. Additionally, our casement windows are equipped with a precision-engineered multi-point locking system that provides enhanced security, giving you peace of mind knowing that your home is protected against intruders. The heavy-duty stainless steel hinges and ergonomic handles ensure smooth and effortless operation, allowing you to open and close the window with ease for many years to come.

In addition to its exceptional performance, our aluminum-plastic co-extrusion casement window features a stunning oak wood-grain finish that adds warmth, character, and timeless elegance to any home. The wood-grain texture is created using advanced transfer printing technology, perfectly replicating the natural look and feel of real wood, without the high maintenance requirements and environmental impact of traditional wooden windows. Unlike real wood, which requires regular painting, staining, and sealing to prevent rot, warping, and insect damage, our wood-grain finish is incredibly durable and low-maintenance. It is resistant to fading, chalking, peeling, and corrosion, ensuring that it retains its beautiful appearance for decades with minimal upkeep. The warm, natural tones of the oak finish complement a wide range of architectural styles and interior design schemes, from traditional to modern, making it a versatile choice for any home. We also offer a variety of other wood-grain and solid color options to suit your personal taste and design preferences.
