The history of the sliding sash

Sliding sash windows originated in the 17th century and have remained a consistent, recognisable window design for centuries. Their classic frames and ease of use go a long way to explaining why they remain such a popular choice today.

Originally crafted from timber, the sliding sash is a simple yet ingenious design: two vertically sliding panels, or sashes, that can each be opened independently to regulate airflow through a room. Over the centuries, the style became emblematic of Georgian and Victorian architecture, adorning the facades of grand townhouses and humble cottages alike, and it remains one of the clearest markers of a period property today.

Benefits of uPVC sliding sash windows

Lorimer uPVC sliding sash windows don’t just transform the elegance of a home internally; they also bring a range of practical benefits with them, from improved security and energy efficiency to easier cleaning and lower maintenance than timber.

Natural light enhancement

Made up of two large panes of glass, sliding sash windows are an excellent way to increase the flow of natural light into a home. We particularly love them in living rooms, where they make a real statement while maximising the amount of daylight flooding the space.

Versatile ventilation

The sliding sash design allows for flexible ventilation, with the top and bottom sashes able to open to different heights independently. This gives you far more control over airflow than a single-opening window, so you can create the perfect balance of fresh air throughout the seasons.

Sleek profile

The slim, clean lines of the Lorimer uPVC sliding sash window bring a contemporary edge to a traditional style, without compromising the period character of the property.
