The Story
Sash window glazing bead is the slim timber moulding that holds glass securely within a traditional single-glazed sash frame. Available in 1.2m lengths, it suits repair, restoration and full replacement projects, helping to maintain a draught-free, watertight seal in period and listed properties.

What it's used for
- Retaining single-glazed panes within traditional timber sash window frames, preventing lateral movement and rattling.
- Repairing or replacing damaged or rotten glazing beads on existing sash windows in period, Victorian and Edwardian properties.
- Full sash window restoration projects where all components are being renewed to original specification.
- Use alongside other sash window parts such as staff beads, parting beads and sash horns to complete a like-for-like repair.
Fitting and handling
Store the glazing bead flat in a dry, well-ventilated space and allow it to acclimatise to the room temperature for at least 48 hours before fitting, particularly in older properties where humidity can vary. Fix using panel pins or purpose-made glazing bead clips, ensuring the bead holds the glass firmly against the putty or glazing tape without bowing. Finish with a suitable timber primer and paint to match the existing window joinery and to protect the bead from moisture ingress.
FAQ
What is a sash window glazing bead and why does it matter?
A glazing bead is a slim strip of profiled timber pinned around the inside of a sash frame to hold the glass pane in place. Without it, the glass can shift, allowing draughts and water to penetrate the frame. Keeping the bead in good condition is essential to the performance of a traditional sash window.
Can I use this glazing bead on a double-glazed sash window?
This bead is designed for traditional single-glazed sash windows. Double-glazed sash units require a deeper, wider bead profile to accommodate the increased glass thickness. If you are unsure of the correct profile for your window, contact Nottage Timber Merchants and we can advise before you order.
How much glazing bead do I need per sash window?
A standard sash requires bead on all four sides of each glazed pane. Measure the perimeter of each pane, add a small allowance for mitre cuts, and divide by 1.2 m to calculate the number of lengths required. It is good practice to order one extra length to allow for any waste or miscuts on site.
