Casement Window Systems: These aluminum casement windows feature sashes that open and close with horizontal embedding. They are categorized by opening methods: inward-opening, outward-opening, and tilt-inverting.
Inward-opening models offer easy cleaning, while outward-opening ones are widely used in various decorative settings due to their large opening area, excellent ventilation, superior sealing performance, and outstanding sound insulation and thermal insulation. For high-rise residents, wind pressure resistance is crucial to withstand extreme weather conditions. The sash is secured by a multi-point locking system, ensuring reliable airtightness and security.
