Arched Aluminum Casement Window with Grille | Premium Matte Black Double Sash

Arched aluminum casement window with grille is the perfect fusion of timeless architectural beauty and contemporary engineering excellence. Olis Metal specializes in crafting these distinctive windows that add a touch of elegance and character to any building facade. Our arched windows feature the classic curved top design paired with durable aluminum construction and decorative grilles, creating a stunning focal point that enhances both the interior and exterior aesthetics of your property.

The graceful arch shape has been a staple of architectural design for centuries, evoking a sense of grandeur and sophistication. Our arched aluminum casement window with grille reinterprets this classic design for modern construction, offering the same visual appeal with significantly improved durability, energy efficiency, and low maintenance requirements compared to traditional wood or vinyl alternatives.

The defining feature of our arched aluminum casement window with grille is its elegant curved top, which adds architectural interest and visual height to any room. The half-round arch is complemented by a symmetrical decorative grille pattern that creates a classic divided-light appearance without compromising the window’s performance or ease of use.

Our double casement design features two operable sashes that open outward from the center, providing maximum ventilation and unobstructed views when fully open. The precision-engineered hinges allow the sashes to open to a full 90 degrees, making it easy to clean both sides of the glass from inside the building. The slim frame profile maximizes glass area, flooding interiors with natural light while maintaining exceptional structural strength.

The decorative grilles are available in multiple patterns and configurations, allowing you to customize the look of your windows to match your architectural style. Whether you prefer a simple colonial grid, a more intricate diamond pattern, or a custom design, we can create the perfect grille to complement your project.

All our arched aluminum casement windows with grille are constructed using high-grade 6063-T5 aluminum alloy, renowned for its exceptional strength, durability, and corrosion resistance. This premium material ensures that our windows will not warp, crack, rot, or fade over time, even when exposed to harsh weather conditions and extreme temperature fluctuations.

We use advanced CNC machining technology to achieve precise cuts and perfect alignment of all window components, including the complex curved arch frame. The frames are finished with a multi-stage powder coating process that creates a durable, scratch-resistant surface available in over 200 standard colors and custom RAL matches. The matte black finish shown in our images is one of our most popular options, providing a sleek, modern look that complements both traditional and contemporary architecture.

Our manufacturing process adheres to strict ISO 9001 quality control standards, with every window undergoing multiple inspections at each stage of production. We source all our materials from certified global suppliers, ensuring consistent quality and performance in every product we deliver.

Beyond their stunning aesthetic appeal, our arched aluminum casement windows with grille deliver exceptional performance across all key metrics. The integrated thermal break system disrupts heat transfer through the frame, significantly improving energy efficiency and reducing heating and cooling costs for building owners.

We offer a range of high-performance glass options, including double-glazed insulated glass units that provide excellent thermal insulation and sound attenuation. Our windows can block up to 35 dB of external noise, creating a quiet and peaceful indoor environment even in busy urban areas.

The multi-point locking system enhances security, preventing forced entry and providing peace of mind for homeowners and business owners alike. The weatherstripping around the entire perimeter of the sash creates a tight seal, preventing air and water infiltration and ensuring the window remains draft-free and watertight even during severe weather events.

Our aluminum windows are virtually maintenance-free, requiring only occasional cleaning with mild soap and water to keep them looking like new. The durable powder-coated finish resists fading, chipping, and corrosion, eliminating the need for repainting or refinishing for decades.

Our arched aluminum casement window with grille is incredibly versatile and suitable for a wide range of architectural styles and applications. They are particularly popular for traditional and historic-style homes, including colonial, Victorian, and Mediterranean designs, where they add authentic architectural detail and charm.

These windows are also an excellent choice for modern and contemporary homes, where the contrast between the classic arch shape and the sleek black aluminum frame creates a striking visual statement. They work beautifully as accent windows above entry doors, in stairwells, or as standalone features in living rooms, bedrooms, and dining areas.

For commercial applications, our arched aluminum casement windows with grille are ideal for hotels, restaurants, office buildings, and retail spaces that want to create a distinctive and memorable aesthetic. They are also widely used in institutional buildings such as churches, schools, and government facilities where both beauty and durability are essential.

We understand that every project is unique, which is why we offer extensive customization options for our arched aluminum casement windows with grille. You can choose from a wide range of sizes, from small accent windows to large statement pieces that span entire walls.

In addition to our standard grille patterns, we can create custom grille designs to match your specific architectural requirements. We also offer a variety of glass options, including clear, tinted, frosted, and laminated glass, as well as low-emissivity (Low-E) coatings that further improve energy efficiency.

Our windows are available in a full range of colors and finishes, including matte, gloss, and textured options. We can also match custom colors to your project’s specifications, ensuring a seamless integration with your building’s overall design.
