Specifications

What it's used for

• Replacing a damaged or rotted bottom rail on the upper sash of a double-hung timber sash window
• Restoring listed and heritage property sash windows where like-for-like timber profiles are required by planning conditions
• Matching existing joinery during full sash refurbishment alongside new glazing beads and pulley stiles
• Cutting to length on site when replicating non-standard window widths in period properties

Fitting and handling

Before fitting, allow the rail to acclimatise inside the property for at least 48 hours to reduce movement after installation. Prime all faces, including any cut ends, before glazing and fix using seasoned PVA wood adhesive along with appropriate hardwood pins or screws, countersunk and filled, prior to a final painted finish. Store flat and off the ground in a dry, ventilated space to avoid any twist or distortion before use.

FAQ

What is a top sash meeting rail and where does it sit in the window?

The top sash meeting rail is the lowest horizontal member of the upper sash. It sits at roughly mid-window height, overlapping with the upper rail of the lower sash to create the characteristic central joint you see on a traditional double-hung sash window.

Can I use this meeting rail on a listed building without planning issues?

Timber meeting rails machined to match the original profile are generally acceptable for like-for-like repair on listed buildings, but you should confirm the exact profile requirement with your local conservation officer before ordering. Nottage Timber Merchants can advise on profile options if you contact us with a drawing or sample measurement.

Do I need any other parts alongside the top sash meeting rail?

For a complete draught-resistant repair, pair this rail with a Meeting Rail Connector Strip to reduce air infiltration at the central joint. A matching glazing bead, available separately from Nottage Timber Merchants, is also recommended to secure the glass pane and simplify any future glass replacement.
