A double sash design with a clever opening mechanism allows for a double casement-style aperture, "meaning that both sashes open at a perpendicular angle to the pitched roof, thus creating a maximal open-air space and unimpeded view." Built-in slide rails also project out and abut the lower sash, thus forming a miniature balcony.
