Description
The sash window head & stile section forms the vertical sides of the upper and lower sashes and the horizontal head rail of the upper sash, framing and supporting the glazing. Precision-machined to replicate traditional joinery profiles, it is supplied in 1.2 metre lengths for sash window repairs, full replacements and new joinery work.
Available in single-glazed and heritage double-glazed versions, the double-glazed option features a traditional ovolo profile with a deeper rebate to accommodate a 12mm slim sightline double-glazed unit and a timber glazing bead where required. Choose the version that matches your glazing and existing sash construction.

Fitting and handling
Store the section flat, off the ground, in a dry, ventilated space. Allow it to acclimatise indoors for at least 48 hours before fitting, particularly where humidity differs from storage conditions.
Check the profile and dimensions against your existing joinery before cutting. Assemble using suitable wood adhesive and fixings for the chosen joint construction, ensuring the sash remains square. Lightly sand where needed and apply a suitable timber primer to all surfaces, including cut ends and end grain, before glazing and finishing.
When using 12mm slim sightline double-glazed units, follow all glazing installation instructions supplied by the unit manufacturer.
Changing from single to double glazing increases the sash weight. Have the counterbalance weights and sash hardware checked and adjusted to suit the completed sash.
FAQ
What is the difference between the single-glazed and double-glazed versions?
The single-glazed version is machined for traditional single glazing. The heritage double-glazed version has an ovolo profile with a deeper rebate to accommodate a 12mm slim sightline double-glazed unit and a timber glazing bead where required.
Will this section match my existing sash window?
Check the section’s dimensions and profile against your existing sash before ordering. Traditional sash windows vary, so a matching appearance does not guarantee an exact fit. Contact Nottage Timber Merchants to discuss bespoke machining if your window requires a different section.
Can this section be used on a listed building or in a conservation area?
Suitability depends on the original joinery and the requirements for your property. Confirm the profile and proposed glazing with your joiner and, where required, your conservation officer before ordering or beginning work.
Will I need to change the sash weights when fitting double glazing?
Double glazing typically makes the completed sash heavier. The counterbalance weights will need checking and may require adjustment or replacement so the window opens, closes and stays in position correctly.
