High-Performance Thermal Break Aluminum Tilt & Turn Windows
Engineered for superior energy efficiency, architectural aesthetics, and uncompromised structural stability, Grandor Door Industry Co., Ltd. produces premium European-style thermal break aluminum tilt and turn window systems designed specifically for commercial and high-end residential overseas projects.
Our tilt and turn window systems offer dual operational versatility via a single ergonomic handle gesture. In the tilt position, the top of the sash opens inward, creating a draft-free, rain-protected ventilation channel while maintaining child safety and burglary deterrence. In the turn position, the sash swings inward 180 degrees on robust side hinges, granting full airflow access and allowing complete exterior glass maintenance safely from inside the building.
German Hardware Integration
Equipped with multi-point perimeter locking gear and concealed hinges from top-tier brands (Siegenia, Roto, HOPO) rated for over 50,000 operational cycles.
Polyamide Thermal Insulation
Reinforced PA66GF25 polyamide thermal break strips eliminate thermal bridging between interior and exterior profiles, reducing thermal conductivity.
Triple EPDM Weather Sealing
Continuous co-extruded EPDM gaskets provide multi-stage compression sealing against heavy wind-driven rain, air infiltration, and acoustic noise.
High-Security Engineering
Multi-point mushroom locking studs engage tightly into heavy-duty frame strikers to deliver RC2/RC3 level security protection.
