A carpenter installs a sash weight inside a wooden window frame.

Definition

Noun: A sash weight is a heavy object, typically made of metal, that is used as a counterbalance for a sliding sash window. It is connected by a cord or chain to the sash, making the window easier to open and hold in position.

Usage

A sash weight is a specific component found in traditional double-hung or sliding sash windows. Its primary function is to counterbalance the weight of the window sash.

Examples

• The old window was difficult to lift until we replaced the broken sash weight.
• When renovating the house, they discovered the original cast-iron sash weights inside the window frame.
• The sash weight is attached to a cord that runs over a pulley at the top of the window frame.

Advanced Usage

• Historical context: In older architecture, sash weights were often made of lead or cast iron and are considered part of a building's original fabric during restoration projects.
  • The preservation guidelines required the repair of the original sash weights rather than their replacement with modern springs.
