Sash weights are a type of counterweight used in windows to help them open and close smoothly. They are typically made of cast iron and are attached to the bottom of the window sash with a cord. The weight of the sash counteracts the force of gravity that would otherwise cause the window to close, allowing it to remain open without any additional force.
Sash weights are most commonly used in older homes and buildings, where they are still in their original form. This is because they are a traditional method of window weighting that has been used for centuries. While newer homes may not have sash weights, they can be easily added to existing windows to provide a more traditional look and feel.
Sash weights are also used in some modern windows. In this case, the weights are typically made of plastic or other lightweight materials, and are attached to the window frame instead of the sash. This allows for a smoother operation and prevents the window from slamming shut.
When it comes to installation, sash weights are quite simple. The counterweights are typically attached to the bottom of the window sash with a cord, which is then looped around the weight and secured with a knot. The cord should be long enough to allow the window to open and close without the cord becoming too tight or loose.
Once the sash weights have been installed, they should be regularly checked to ensure they are working properly. If the weight is not properly balanced, the window may not open and close smoothly. If the weight is too light, the window may not stay open.
In addition to providing a smoother operation, sash weights also help to keep the window secure. The weight of the sash counteracts the force of gravity, which can cause the window to be pushed open by strong winds or other external forces. This helps to keep the window securely shut and can also help to prevent burglars from entering the home.
Overall, sash weights are a great way to provide a traditional look and feel to a window, while also providing a smoother operation and helping to keep it secure. They are relatively inexpensive and easy to install, making them an ideal choice for those looking to add a touch of history to their home.
