Georgian PVC sash windows are a modern adaptation of the traditional Georgian sash windows, designed to replicate the classic aesthetic, while offering the benefits of contemporary materials and manufacturing techniques.

These windows use PVC (Polyvinyl Chloride) for the frames and sashes instead of wood, which was the material traditionally used in the Georgian era. The design elements aim to mimic the elegant, symmetrical features of Georgian windows, including the characteristic multiple panes of glass, known as "astragal / integral glazing bars," and the sliding mechanism that allows the window to open vertically.
