Aluminum Casement Windows
Engineering high-performance thermal break aluminum casement window systems for residential, commercial, and high-rise developments worldwide.
Commercial & Residential Grade Aluminum Casement Windows
Manufactured by Foshan Derka Architectural Doors & Windows Co., Ltd., our aluminum casement windows combine structural robustness with superior thermal insulation. Designed with multi-point locking systems and precision EPDM seals, every sash compresses tightly against the frame to deliver outstanding energy efficiency and weather protection across all climate zones.
Structural Durability
Engineered with high-tensile 6063-T5 aluminum profiles featuring wall thicknesses up to 2.0mm to withstand extreme wind loads up to 5000 Pa.
Thermal Barrier Technology
Integrated polyamide PA66 thermal break strips combined with Low-E insulated glass units significantly lower U-values to under 1.4 W/m²K.
Airtight & Watertight
Multi-stage EPDM weather sealing gaskets prevent water penetration during heavy storms and deliver noise reduction performance up to 42 dB.
