Designed to replicate traditional timber box sash windows, our PVC-U sash window (also known as a vertical slider) provide modern day benefits such as unbeatable thermal efficiency without having to compromise on period charm and quality.

Our sash windows are available in a range of colours to suit both new builds and traditional properties, and can be chosen with decorative run-through horns and Georgian bars for authenticity. They also tilt inwards for ease of cleaning.
