DEEZON DE113B Double Inward-Opening Windows: Two Ways to Open, One Standard of Excellence

The DEEZON DE113B double inward-opening system window redefines versatility for modern homes. Designed to offer two distinct opening modes—tilt for gentle ventilation or turn for full cleaning access—this window adapts to your daily needs while maintaining exceptional thermal performance and security.

Dual Functionality, Maximum Comfort
The inward-tilt function allows fresh air to circulate gently while maintaining security and preventing rain from entering—perfect for overnight ventilation or rainy days. When you need to clean the exterior glass or require maximum airflow, the inward-turn mode provides full sash opening from the safety and comfort of your home.

Robust Construction for Lasting Performance
Engineered with a 113mm frame depth and 1.8mm wall thickness from high-grade aluminum, the DE113B delivers exceptional structural integrity. This robust profile ensures the window maintains its shape and sealing performance even under extreme weather conditions, offering long-term durability and peace of mind.

Superior Thermal and Acoustic Insulation
Standardly configured with 5mm+20A+5mm double-glazed insulating glass, the DE113B significantly reduces heat transfer and external noise infiltration. The 20mm argon-filled cavity enhances energy efficiency, keeping interiors comfortable year-round while lowering heating and cooling costs.

Precision German Engineering
At the heart of the DE113B’s smooth operation lies German Wehag hardware, globally recognized for its precision engineering and reliable performance. The multi-point locking system engages at multiple points around the frame, providing heightened security against intrusion. The Germany Hoppe handle, imported for its superior anti-theft performance, offers a comfortable grip and elegant finish. For added flexibility, DEEZON’s independently developed hardware is also available as a trusted alternative.

Safety in Every Detail
The DE113B prioritizes occupant safety with a rounded corner sash profile, significantly reducing the risk of injury from accidental impact—an essential feature for families with children. The screen sash incorporates a high-strength strip lock with a concealed design, offering both durability and tamper resistance for worry-free ventilation.

Engineered for Long-Term Stability
To maintain superior sealing performance over time, the DE113B utilizes an integrally bent aluminum spacer bar. Unlike conventional cut-and-joined corners, this continuous bend eliminates potential leak paths, offering higher strength, better stability, and resistance to deformation. The result is a window that performs flawlessly for decades.

Whether you’re building a new home or upgrading existing windows, the DEEZON DE113B double inward-opening system window delivers the perfect balance of versatility, security, and energy performance.
