What Are Sash Window Weights?

A sash window weight acts as a heavy counterbalance for traditional sliding timber windows, allowing the panels to stay securely in position at any height. These weights ensure smooth, balanced movement, making the window easy to open and close while preventing heavy sashes from slamming shut or falling unexpectedly.

Density

Smooth Operation

High-density lead provides an excellent counterbalance, ensuring timber sash windows slide smoothly and quietly without sticking.

Longevity

High Durability

Corrosion-resistant lead weights offer lifetime durability for new builds and traditional Grade II listed property restorations.

Fitment

Easy Installation

Features a central hole for standard 6mm to 8mm sash cords, utilising easy-to-cut lead for a precise fit inside the window box.

Frequently Asked Questions

How do I choose the correct size of lead sash weight? +

The correct profile size depends entirely on your window frame’s total glass mass and the inner cavity space. As a foundational trade guideline, each individual sash weight should equal approximately half of the total weight of the corresponding window sash panel. Always verify the inner box space dimensions before final ordering to prevent rubbing.

Are lead window weights acceptable for Grade II listed properties? +

Yes. Traditional lead counterweights are highly recommended and widely approved for historical renovations and period restorations. They help maintain original architectural profiles, mechanical authenticity, and structural frame dimensions better than modern spring mechanisms or iron profiles.

Do window counterweights improve building thermal efficiency? +

When counterweights are balanced accurately, they pull the upper and lower sashes flush against the frame timber. This forms a structural seal that eliminates common air gaps, effectively minimising cold drafts, lowering energy loss, and improving year-round indoor room comfort.
