Our Regency Mock Sash Casement windows are perfect for those seeking a traditional sliding sash design without the attached costs. Designed to evoke feelings of London’s grand period terraces, these windows possess all the features of a sliding sash but with standard casement functionality.

Finished with decorative horns to provide an authentic sash appearance, they deliver all the outstanding qualities you would expect from a wooden casement window. If you’re looking for a contemporary take on a classic design, these timber windows are the perfect option.

Available with or without glazing bars, our Regency Mock Sash wooden windows are manufactured in high-quality softwood and come with an array of paint and stain options to choose from.
