Sashless windows are a type of window that has no sashes, frames, or horizontal bars that divide the glass area. Instead, the glass panes simply slide over each other to open and close, creating a seamless, uninterrupted view.

Sashless windows are a popular option for modern buildings and renovations, as they offer a minimalist design that maximizes natural light and ventilation. They also provide a sleek, unobtrusive look that complements a variety of architectural styles.
