What it's used for

  • Replacing a damaged or rotten top rail on an existing upper sash in a period or listed property
  • Forming part of a full sash window rebuild where new upper sash components are required
  • Matching original joinery profiles in heritage restoration projects where continuity of section is important
  • Pairing with other sash window components such as meeting rails, stiles, and glazing bars for a complete upper sash assembly

Fitting and handling

Allow the section to acclimatise indoors for at least 48 hours before fitting, particularly in older properties where humidity levels may differ from storage conditions. The section should be fixed using appropriate wood adhesive and mechanical fasteners suited to the joining method of the existing sash frame, ensuring square assembly before the adhesive sets. Before painting or priming, lightly sand any machined faces and apply a suitable timber primer to all surfaces including end grain to protect against moisture ingress.

FAQ

Will this sash window upper section fit my existing sash window frame?

This section is machined to replicate standard traditional sash window profiles, making it suitable for most period single-glazed sash windows.

Can this timber section be used on a listed building?

Yes. This component is designed to replicate traditional sash window profiles and is well suited to repair and restoration work on listed or heritage properties. It is advisable to confirm the specific profile requirements with your local conservation officer before ordering if you are working under listed building consent conditions.

Good for a quick backdrop
This works well for what I needed – a simple background for my kids’ online school. It’s lightweight and very easy to put together, and it stands up fine without needing to mount anything. The color is listed as black, but it’s more of a dark gray in person. Not a huge deal, just something to be aware of. It’s not super heavy duty, but it does the job for privacy and as a video backdrop. Overall, a good, portable divider that’s quick to set up and works well for light use.
