Specifications

What it's used for

• Replacing damaged or rotten glazing bars in existing single-glazed sash windows
• Restoring period sash windows in listed buildings and conservation areas to original specification
• New sash window construction where authentic divided-light detailing is required
• Matching original bar profiles during full window rebuilds on Victorian and Edwardian properties

Fitting and handling

Allow the timber to acclimatise inside the property for at least 48 hours before fitting, as sudden changes in humidity can cause movement in machined joinery sections. Fix using a suitable wood adhesive combined with fine panel pins or lost-head nails, keeping fixings as discreet as possible on visible faces. Before installation, prime all faces including end grain, then apply your chosen paint or stain system to help the timber resist moisture ingress over its service life.

FAQ

Can these glazing bars be used in listed building repairs?

Yes. The traditional single-glazed profile is appropriate for listed building and conservation area repairs where the original window configuration must be retained. Always confirm the exact profile dimensions with your conservation officer before ordering.

What is the finished size of the glazing bar?

The bars are supplied as machined lengths. For precise finished dimensions to match your existing window, contact Nottage Timber Merchants directly, as profiles can vary by window age and manufacturer. Bespoke sizing is available for restoration projects.

Do I need to treat the timber before fitting?

These bars are supplied unprimed, so priming and painting before and after fitting is strongly recommended, particularly on external sash windows. Apply a microporous primer to all faces, paying close attention to end grain cuts, to give the best long-term protection against weather and condensation.
