Specifications

What it's used for

• Replacing a damaged or rotted lower meeting rail on an existing double-hung sash window during repair work
• Full sash window replacement projects where new meeting rails are required to maintain correct period proportions
• Heritage and listed building restoration, where the grooved or rebated profile must match the original joinery detail
• New joinery fabrication by window makers and joiners producing traditional sash windows to period specification

Fitting and handling

Allow the rail to acclimatise in the room or workshop where it will be fitted for at least 48 hours before cutting or fixing, particularly in older properties with higher humidity levels. The rebated profile should be fitted with the rebate facing inward against the upper sash to create a tighter weathered joint, while the grooved profile is intended to house a glazing bead in the conventional manner. Before priming and painting, ensure all cut ends are sealed with an end-grain preservative or primer to protect against moisture ingress.

FAQ

What is the difference between the grooved and rebated lower meeting rail profiles?

The grooved profile is machined with a channel along the face to accept a glazing bead, which is the more common configuration in traditional sash window joinery. The rebated profile is cut with a stepped rebate that overlaps against the upper sash when closed, providing a tighter mechanical fit and improved resistance to wind and rain.

Will these meeting rails suit a listed building or conservation area window repair?

Yes. Both profiles are machined to replicate traditional period joinery details, making them suitable for use on listed buildings and windows in conservation areas where like-for-like replacement is required. We recommend confirming the exact original profile with your joiner or conservation officer before ordering.

Can I order a longer length or a custom cut to size?

The standard stock length is 1.2 metres. If you need a longer rail or a specific cut length for your project, contact Nottage Timber Merchants directly and we will advise on availability and cutting options for your requirements.
