Product Features

Elegant Vertical Sliding with French Proportions
The sash glides vertically within a slim frame, featuring delicate mullions and balanced symmetry that evoke classic French architecture, from Parisian apartments to country manors.

Smooth Balance System for Effortless Operation
Precision spring or counterweight mechanism neutralizes the sash weight, allowing one-touch lifting and secure holding at any open height with refined, gentle movement.

Dual Sash for Natural Convection Ventilation
Both upper and lower sashes open independently, letting warm air escape from the top while drawing in cool air from the bottom, enhancing indoor air circulation naturally.

Tilt-In for Easy Cleaning from Inside
The lower sash tilts inward from the top, allowing safe, ladder-free cleaning of exterior glass while preserving the window’s elegant French appearance.

Superior Thermal and Acoustic Insulation
Multi-chamber thermal break profiles with high-performance insulating glass reduce heat loss and outside noise, while compression seals deliver excellent weather resistance for year-round comfort.
