Casement Series
Elegant UPVC Casement Windows
Designed for maximum fresh airflow, exceptional acoustic sealing, and panoramic natural light in residential and commercial spaces.
Acoustics & Airflow
Capture 100% of the breeze with airtight peace of mind.
Winplast casement windows open outward or inward on high-strength stainless steel friction stays. When locked, dual EPDM rubber compression gaskets seal tightly against the frame to keep outdoor noise and torrential rain completely outside.
- 100% Ventilation: Opens fully to channel refreshing cross-breezes inside.
- Superior Acoustic Seal: Dual compression gaskets cut down street traffic noise.
- Heavy SS Friction Stays: Holds window open at any angle without wind slamming.
- Multi-Point Security: Single handle locks top, center, and bottom firmly.

Side-Hung Casement

Top-Hung (Awning)

French Casement (Double)
