Enhance your home with Yorkshire Sash Windows
Yorkshire sash windows are a traditional and practical choice for maximising natural light while preserving the character of a property. Combining a sliding mechanism with draught-proofing technology, featuring our patented seal system for higher performance levels, our Yorkshire Sash Windows make interiors feel brighter and more spacious.
Despite their robust timber construction, the sashes glide easily along their tracks, delivering long-term durability and reliable performance.
Yorkshire sash windows are ideal where space is limited, as the sashes slide horizontally. This makes them well-suited to kitchens, stairwells and rooms overlooking paths or walkways, as well as period and heritage properties. We also provide narrow sash rails to meet specific requirements for historic properties subject to conservation and listed building regulations.
Each of our Yorkshire sash windows can be configured to suit the size of the opening and the style of the building. Optional ventilation features allow controlled airflow, making Yorkshire sash windows a comfortable and practical choice for bedrooms and living spaces alike.
Our curated range of Yorkshire Sash Windows enhances the aesthetic while ensuring increased levels of security. For added protection, toughened glass can be specified to comply with Part Q building regulations.

Yorkshire Sash Windows: Frequently Asked Questions
What are Yorkshire sash windows?
Yorkshire sash windows, also known as horizontal sliding sash windows, are a traditional style of window that features sashes sliding horizontally rather than vertically. This design is particularly popular in rural and historic properties, especially in northern England. Known for their simple functionality, Yorkshire sash windows offer a practical solution for properties where vertical sliding sashes may not be as suitable.
Why are horizontal sash windows called “Yorkshire” sash windows?
The term Yorkshire sash windows originates from their historical association with the county of Yorkshire in England, where this style was widely used. The horizontal sliding mechanism was ideal for the region’s architectural needs, particularly in cottages and farmhouses, where space constraints or structural factors made horizontal movement more practical. The name has since become synonymous with this distinct style of sash window.
Do Yorkshire Sash windows come with double glazing?
Yes, we offer double glazing as a standard for improved efficiency and noise reduction. We also provide the option of slimline double glazing to maintain the traditional appearance of your Yorkshire Sash Windows.
