uPVC Vertical Slide Windows

A vertical sliding window, also known as a sash window, is a window that opens by moving one or more panels (sashes) up and down within the frame. Vertical sliding windows are popular for their classic look, smooth operation, and ability to control ventilation, and they are commonly seen in traditional and period-style homes.

Modern sliding windows, like those manufactured by us here at Trade Window Centre, feature quality weatherproofing to reduce heat loss, block drafts, and improve insulation. However, older or poorly sealed sliding windows may allow air leakage, making them less efficient than other window types.

The cost of a sliding window varies widely depending on factors like the size of the window, the type of glazing, and how complex the installation is. Larger windows and high‑performance glazing will generally cost more, while smaller, simpler units with standard glass are usually less expensive.
