Casement Window

Introducing the DEEZON DE90B—an innovative micro-ventilation system window designed for modern living spaces that demand both fresh airflow and panoramic sightlines. Featuring a fixed 195mm-wide ventilation sash, this window allows continuous gentle airflow while maintaining an expansive view through its large fixed glass panel. The clean, minimalist aesthetic seamlessly complements contemporary architecture, available in refined color finishes to suit any design palette.

Engineered for intelligent performance, the DE90B is built with a robust 1.8mm wall thickness frame and precision-matched hardware—optionally available from German WEHAG or DEEZON’s independently developed system. The multi-point locking mechanism ensures enhanced security, while the advanced sealing system delivers superior airtightness, water resistance, and thermal insulation. With a standard glass configuration of 5mm+20A+5mm insulating glass, it effectively reduces noise transmission and maintains a comfortable indoor environment year-round.

The unique micro-ventilation design provides controlled airflow without fully opening the window, making it ideal for bedrooms, nurseries, or spaces where security and continuous fresh air are priorities. Its integrally bent aluminum strip and precision seal technology ensure long-term stability and durability.

Built not just to ventilate, but to inspire—the DEEZON DE90B transforms every window into a source of fresh air, expansive views, and lasting comfort.
