What Are Sliding Sash Windows?


What are sliding sash windows?

Sash windows are a type of window that opens vertically. They consist of two framed window panes, one in front of the other. This is more specifically referred to as a sliding sash window. Sash windows are typically found in historic homes and are generally associated with traditional architecture and design.

The history of sash windows

The origins of sash windows are unclear, but they are believed to have originated in the Netherlands in the 16th century. They were introduced to England in the 17th century, and quickly became popular due to their energy efficiency and ease of use. Sash windows were also seen as a status symbol, and were often found in the homes of wealthy people.

Types of sash windows

There are two main types of sash windows: single-hung and double-hung. Single-hung sash windows only allow the bottom sash to move, while double-hung sash windows allow both the top and bottom sashes to move. Double-hung sash windows are more common than single-hung sash windows, as they provide better ventilation.

Materials for sash windows

Sash windows can be made from a variety of materials, including wood, uPVC, and aluminum. Wood is the traditional material for sash windows, and it is still a popular choice today. Wood sash windows are known for their beauty and durability. uPVC sash windows are a more affordable option, but are a less sustainable option than wood. Aluminium sash windows are another type of energy-efficient sash windows, but they can be more expensive than wood or uPVC sash windows.
