Y103 Aluminum Casement Window for Double & Triple Pane Glazing

The DERCHI Y103 is an outward-opening aluminum alloy casement window, featuring 6063-T5 thermal break aluminum profiles with a 2.0 mm aluminum thickness and a 103 mm frame depth, meeting wind pressure resistance and energy-saving requirements. It is suitable for residential window renovations and modern casement window designs.

This window can be equipped with double or triple-pane tempered glass, with optional Low-E coating and argon gas filling. You can choose laminated glass, tinted glass, or reflective glass, select powder coating or PVDF coating (including a black option for easy comparison with black double-hung windows), add magnetic nylon screens, and choose security hardware such as a six-point locking system. We provide online technical support, and the delivery time is typically 25-35 days after drawing confirmation and deposit payment. A 10-year warranty is also provided.
