The Story
Sash window cill timber provides the machined softwood base profile needed to support and drain a traditional sash window correctly. Available in a 1.2 m length at a consistent finished profile, it suits period repairs, listed building restorations, and full window replacements where matching original joinery details matters.
Specifications
| Property | Detail |
|---|---|
| Material | Softwood timber |
| Finish | Machined / planed to profile |
| Length | 1.2 m (1200 mm / 4 ft) |
| Profile | Sash window cill profile with weathered face and drip groove |
| Use Class | UC2 (covered, above ground joinery applications) |
What it's used for
- Replacing a rotted or damaged cill on an existing timber sash window without disturbing the surrounding frame
- New sash window installations in period properties, listed buildings, and conservation areas where traditional profiles are required
- Matching the original cill profile on Victorian and Edwardian window refurbishments to maintain historical character
- Supplying a ready-machined component to joinery workshops producing bespoke sash window units
Fitting and handling
Allow the timber to acclimatise inside the property for at least 48 hours before fitting, particularly during winter months when internal humidity differs significantly from external conditions. Prime all faces, including the back and ends, before installation to slow moisture uptake and reduce the risk of cupping or splitting after fixing. Store the lengths flat and supported at regular intervals to prevent bowing while on site.
FAQ
Is this cill profile suitable for listed buildings and conservation area properties?
Yes. The machined softwood profile replicates the traditional weathered cill shape found on original sash windows, making it appropriate for listed buildings and conservation area work where like-for-like repair is a common planning requirement. Always confirm the specific profile with your local conservation officer if in doubt.
Can I order a custom length or a different timber species for my sash window cill?
Nottage Timber Merchants can supply custom lengths and alternative species such as oak or accoya on request. Contact the yard directly in Bridgend and the team will advise on availability, lead times, and pricing for non-standard requirements.
Does the cill need treating before fitting outdoors?
Yes. Bare machined softwood should be treated with a suitable exterior primer or preservative on all faces before installation. Pay particular attention to end grain, which absorbs moisture most readily. A full paint system will give the longest service life on an external cill exposed to the South Wales climate.
