What is a Sash Window:
Everything You Need to Know

Sash windows have been around for hundreds of years and are a popular choice among homeowners for their timeless elegance, practicality, and energy efficiency.

In this ultimate guide, we’ll explore everything you need to know about sash windows, including their history, types, materials, benefits, and maintenance.

History of Sash Windows

Sash windows have been around since the 17th century and were first popularized in England during the Georgian and Victorian eras. They were a popular choice among the upper classes due to their elegant appearance and practicality. The design of sash windows has evolved over time, with early models featuring lead weights to counterbalance the sashes and modern versions incorporating spring balances for easier operation.

Types of Sash Windows

There are two main types of sash windows: single-hung and double-hung. Single-hung sash windows have one movable panel, while double-hung sash windows have two movable panels. Double-hung sash windows are the more popular choice among homeowners as they provide better ventilation and are easier to clean.
