PVC hand crank casement windows combine classic side-hinged design with modern performance and durability. Designed to open outward with the turn of a smooth-operating crank handle, these windows provide excellent ventilation control, unobstructed views, and superior sealing performance. Crafted from high-quality uPVC profiles and internally reinforced with galvanized steel, our casement windows are built for long-lasting strength and weather resistance. The multi-chambered frame enhances thermal insulation, while compression seals along the sash perimeter ensure airtight and watertight performance—ideal for energy-efficient homes and buildings. Each window is equipped with a corrosion-resistant crank handle, multi-point locking system, and friction hinges for secure, effortless operation. Glazing options include single, double, or triple glass units with Low-E coating, argon gas fill, and laminated or tempered glass for added insulation and security. Available in a variety of frame colors, finishes, and grille patterns, our hand crank casement windows can be tailored to suit modern or traditional designs. Easy to maintain and built to meet international standards such as NFRC and CE, they are ideal for residential homes, villas, and commercial buildings in diverse climates.
