    User-friendly: the window's 95˚ opening
    makes for easy maintenance.

    Weather seals: High-quality continuous
    compression weather seals on frames and
    sashes for maximum air and water tightness.

    Secure: even when the window is
    open for ventilation, its partial
    opening in the upper part of the sash
    limits the risk of forced entry and
    protects children and adults against
    potential accidents and injuries.
