The C113 outward-open window is constructed using 6060-T66 aluminum profiles, a premium-grade alloy known for its excellent strength-to-weight ratio and corrosion resistance. With a profile thickness of 1.8 to 2.0 mm, the window meets and exceeds China's new national standard for aluminum windows, ensuring enhanced structural rigidity and superior deformation resistance under wind loads and temperature variations.
A defining feature of the C113 is its full glue-injection process. Integrated glued corner brackets create a seamless monolithic structure at every corner joint, significantly improving overall window stability, airtightness, and long-term durability. This construction method eliminates the gaps and weak points commonly found in mechanically fastened corners.
At the heart of the C113's energy efficiency is its multi-chamber thermal break design utilizing PA66GF25 insulation strips. This polyamide-based thermal break, reinforced with 25% glass fiber, effectively interrupts heat transfer through the aluminum frame, ensuring the interior surface stays comfortable year-round — warm in winter and cool in summer.
The system employs a unified isothermal line principle: the glass centerline, thermal break strip, and equal-pressure sealing strip are all aligned on the same axis. This coaxial design optimizes thermal performance by reducing thermal bridging and creating a consistent insulation plane across the entire window cross-section.
The C113 outward-open window features a triple sealing system that provides robust defense against wind, driving rain, outside noise, and extreme temperature fluctuations. Each sealing layer serves a specific function, working together to deliver exceptional airtightness and watertightness performance.
The C113 is equipped with CMECH hardware, a recipient of the German Red Dot Design Award for excellence in product design. The hardware system has been rigorously tested to 30,000 open-close cycles, ensuring smooth, reliable operation for years of daily use. As a trusted casement window supplier, ALPES selects only premium hardware partners to guarantee long-term performance and customer satisfaction.
The C113 comes standard with a black high-definition anti-PM2.5 mesh screen. This fine-mesh screen provides effective protection against fine particulate matter, insects, and debris while maintaining excellent outward visibility and air circulation. The black finish reduces glare and blends seamlessly with the window frame for a clean, modern aesthetic.
ALPES offers a range of standard color finishes to match diverse architectural styles:
Custom color matching is also available to meet specific project requirements. Glass configurations can be customized with various insulated glass options, tints, and styles to achieve desired thermal performance, sound insulation, and aesthetic goals.
The C113 outward-open window is well-suited for a wide range of residential and commercial applications, including luxury villas, high-rise apartments, hotels, and office buildings. Its outward-opening design is particularly advantageous where interior space is at a premium, as the sash swings outward without encroaching on usable floor space.
Key advantages of the C113 series include:
The C113 outward-open window represents a balanced combination of structural integrity, thermal performance, and refined design. Backed by ALPES's 100,000 m² manufacturing facilities in Foshan and Zhaoqing and built with internationally sourced components, this model delivers reliable performance for demanding architectural projects. Whether you are an architect, contractor, or developer, the C113 series offers a dependable outward-opening casement solution built to international quality standards.
