Designed in Foshan to satisfy stringent international building standards including AS2047, CE, and NFRC. Each system delivers verifiable acoustic insulation, air impermeability, and typhoon water-tightness.
Innovative hardware configuration enabling dual operation: tilt inward for secure draft-free ventilation or glide smoothly along heavy-duty bottom tracks to save interior space.
Engineered for mid-rise to high-rise luxury towers. Features flush profile alignments, multi-cavity EPDM sealing gaskets, and internal swing mechanisms for safe exterior glass cleaning.
Reinforced architectural framing capable of supporting oversized glazed sashes up to 180kg. Certified under European standard test procedures for wind load deflection and extreme weather resilience.
Bottom-projecting awning geometry permits continuous natural airflow while deflecting monsoon downpours away from residential living quarters and hotel guest suites.
Equipped with reinforced multi-chamber insulation profiles to dramatically reduce solar heat gain coefficient (SHGC) and internal condensation in humid tropical and subtropical environments.
Slim-line architectural sightlines optimized for contemporary urban villas and resort villas, offering maximum daylight transmission without compromising wind resistance or structural rigidity.
Integrated 100mm frame system incorporating high-tensile 304 stainless steel insect and security mesh, outward swing sashes, and patented Four-Side Six-Point anti-theft locking points.
Multi-functional dual-opening architecture designed for tropical coastal properties, combining the rainy-day ventilation of a top-hung awning with the rapid purge ventilation of a side-hung casement.
Specifically tuned for metropolitan roadside apartments, hotels, and airport-adjacent residences. Incorporates asymmetric acoustic laminated glass and triple automotive-grade sealing barriers.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. subjects every casement system to certified testing. The performance data below serves as our baseline specification for project tenders.
| Performance Criteria | Testing Standard | DERCHI Tested Rating | Architectural Benefit |
|---|---|---|---|
