Casement & Aluminum Windows: Engineering Excellence
Casement windows are connected by a pair of hinges and can be operated from the side. They can be used in pairs or individually.High-quality casement windows provide excellent security with multi-point locks, better vision, easy cleaning and unlimited design possibilities. For projects requiring metallic frameworks, our partner network of certified aluminum windows suppliers offers complementary solutions that integrate seamlessly with casement systems.

Energy Efficiency
Certified for various performance levels by organizations such as NFRC, CSA and Energy Star. Our aluminum windows series achieves 35% better thermal performance than industry standards through patented thermal break technology, making them ideal for passive house projects.
High Security
Multi-point locking system tightly seals the window sash, providing excellent anti-theft and security. As a leading aluminum windows manufacturer, enhances this through 3mm reinforced corners and military-grade locking mechanisms tested to BS PAS 24:2016 standards.
Material Innovation
Customizable in a variety of colors, sizes, finishes, and materials:
· Vinyl: Affordable low-maintenance option
· Aluwood: Woodgrain aesthetics with aluminum core
· Aluminum windows (15字节): High-strength profiles for structural glazing
Our aluminum windows suppliers (23字节) provide exclusive access to aerospace-grade 6063-T5 aluminum alloy, achieving 50% higher tensile strength than conventional materials.
Smooth Operation
High-quality hardware provides smooth and easy operation for opening and closing windows. The aluminum windows manufacturer (27字节) division developed friction-reducing nylon rollers that maintain functionality even in -40°C Arctic conditions, certified by TÜV SÜD.
