Customers Often Ask

Here's some of the questions we often get asked about sash windows:

What are sash windows?
Sash windows are a type of window characterised by two framed window sashes set one behind the other, which slide vertically to open and close. These windows are typically found in period homes and are known for their elegant, traditional design. The sashes move smoothly within the frame, guided by vertical grooves and balanced by weights connected by cords and pulleys, often concealed inside the frame. This design allows the windows to open without swinging outward or inward.
What are the benefits of sash windows?
Sash windows offer several benefits that make them a popular choice, especially for period homes. Firstly, they provide a classic aesthetic that enhances the historical charm and character of a property. They are also designed for high thermal efficiency with features like ultra-thin double glazing that helps retain heat and reduce energy costs. The smooth operation of sash windows, facilitated by well-balanced sashes, allows for easy opening and closing. And, the variety of designs and customisation options available means they can be tailored to match any home’s exterior beautifully.
Are sash windows energy efficient?
Yes, modern sash windows are designed to be energy efficient. While traditional sash windows were not as effective at insulation, contemporary versions incorporate advanced glazing technologies, such as double glazing and even triple glazing in some cases. These innovations significantly enhance the thermal efficiency of the windows, helping to keep the home warm in winter and cool in summer, thereby reducing heating and cooling costs. The tight fit of the sashes also minimises drafts, further improving their energy efficiency.
Do sash windows open in or out?
Sash windows do not open in or out, they are designed to open vertically, with the sashes sliding up and down within the frame. This feature makes them particularly suitable for locations where it is impractical to have windows that project beyond the building’s exterior, such as along sidewalks or in close proximity to neighbouring properties.
