About Sash Window Weights
Sash window weights, also known as hung sash counterweights, are an essential component in traditional sash windows. Attached to the sash cords via pulleys, these weights provide the perfect counterbalance to hold the window in any open position. This clever mechanism ensures smooth, quiet operation and prevents the sash from slamming shut or sticking.
Benefits of Lead Sash Window Weights
Lead sash window weights offer a reliable, time-tested solution for traditional and modern window designs. Lead’s high density allows more weight to fit into smaller sash boxes, making it ideal for older windows with limited space or for upgrading to heavier glazing such as double glazing. Here are the key advantages:
- Superior balance and smooth operation – ensures the sash stays at the desired height.
- Space efficiency – denser than cast iron, allowing the ideal weight in smaller box sections.
- Durability – lead resists corrosion and provides long-lasting performance.
- Customisable – easily cut to length and adjusted on-site.
- Authentic heritage look – perfectly suited to period restorations and listed buildings.
Why Choose DKL Metals’ Lead Sash Weights?

Why Use Sash Window Weights Instead of Spiral Balances?
While spiral balance mechanisms are more common in modern PVC or aluminium windows, sash weights remain the top choice for timber and heritage designs. They deliver a smoother, more authentic movement and are far easier to maintain long-term. A simple cord replacement can restore full operation even after decades of use, making sash weights the more sustainable and repairable option.
Frequently Asked Questions About Sash Window Weights
What are sash window weights made from?
Traditional sash weights were made from cast iron or lead due to their density. At DKL Metals, we focus on high-quality lead weights for superior balance and smooth operation, ideal for both single and double-glazed sashes.
How do I choose the right size of sash weight?
The correct size depends on your sash’s total weight and frame height. As a general rule, each sash weight should be approximately half the total sash mass. Always measure your window box space before ordering to ensure compatibility.
Can lead sash weights be adjusted or cut?
Yes, one of the main benefits of lead weights is that they can easily be cut to the required length to achieve the exact balance your window needs.
Are lead sash window weights suitable for listed buildings?
Absolutely. Lead sash weights maintain the traditional counterbalance design that preserves the authenticity of period windows and heritage restorations while delivering smooth, reliable operation.
Do sash window weights improve energy efficiency?
Properly balanced sash windows help maintain a tight seal when closed, reducing draughts and heat loss. This makes them more energy-efficient and comfortable year-round.
Can you get custom sized sash window weights?
Yes. DKL Metals provides cut-to-size lead sash weights on request. Simply contact us with your sash measurements, and our team will help you find the correct fit.
How long do lead sash weights last?
Lead sash weights are incredibly durable and can last for several decades without corrosion or degradation, especially when installed properly within traditional timber sash boxes.
