Manufactured by Guangdong Dejiyoupin Doors and Windows Co., Ltd., our aluminum sliding window collection brings together multi-chamber polyamide thermal break profiles, precision stainless steel guide tracks, and advanced weather-sealing gaskets. Every model is rigorously designed to satisfy European building codes (EN 14351-1), offering outstanding wind-load resistance, acoustic suppression, and water tightness for modern residential estates, commercial developments, and hospitality projects.
Hybrid functional system combining smooth horizontal sliding with inward tilting ventilation for high-rise acoustic and thermal security.
Robust 105mm system depth engineered to support double and triple insulating glass units, integrated flyscreens, and heavy wind ratings.
Minimalist narrow-profile horizontal slider tailored for multi-family residential complexes and contemporary European urban apartments.
Reinforced profile structure suitable for large horizontal spans, balcony access windows, and panoramic terrace enclosures.
Enhanced multi-barrier acoustic and thermal insulation system designed specifically to resist aggressive rainstorms and cold climates.
Sleek European styling integrated with state-of-the-art energy-conservation technology for luxury villa renovations and low-energy homes.
