An Economical Nod to the Traditional

Mock sash windows are a cost-effective alternative to traditional sash windows, letting you retain the period charm of your property without incurring the expense of a classic sash window.

More than Just an Attractive Facade

Our timber mock sash windows echo the elegance of traditional sliding sash windows. But the similarity doesn’t stop at appearances. These windows also come with all the essential benefits of a standard uPVC casement window: low maintenance, exceptional energy efficiency, and outstanding security.


Spot the Subtle Differences

At a glance, our timber mock sash windows closely resemble traditional sashes. The main difference? While sash windows feature two panels that slide vertically, mock sashes boast one fixed pane and a movable panel that opens like a casement. If your property lacks the wall depth to accommodate a sliding sash window, mock sash windows serve as an excellent alternative.
