$3.45The Story
The sash window inner casing is the structural timber lining that forms the interior frame of a traditional sliding sash window, housing the sash weights and channels that allow the sashes to travel smoothly. Supplied by Nottage Timber Merchants in a 1.2m length, it is precision-machined for accurate integration with other sash window components.
Specifications
| Property | Detail |
|---|---|
| Material | Timber |
| Nominal Length | 1.2m (1200mm / 4ft) |
| Profile | Inner casing section |
| Use | Interior sash window framing |
What it's used for
- Forming the internal lining of a traditional single-glazed sliding sash window box frame
- Heritage restoration and like-for-like replacement in listed buildings and period properties
- Repair of Victorian and Edwardian sash windows where the original casing timber has decayed or distorted
- New-build sash window joinery where a traditional box frame construction is specified
Fitting and handling
Before installation, store the casing flat and off the ground in a dry, well-ventilated space and allow it to acclimatise to the internal conditions of the building for at least 48 hours. Fix using appropriate timber screws or nails, ensuring the casing is plumb and square before securing permanently, as any twist will affect how the sashes slide. Once fitted, apply a primer and paint finish suitable for internal joinery to protect the timber and help reduce draughts at the frame junctions.
FAQ
What is a sash window inner casing and how does it differ from the outer casing?
The inner casing forms the visible interior lining of the sash window box frame, sitting on the room side of the wall. The outer casing faces the exterior. Together they create the box that conceals the sash weights and pulley system.
Is 1.2m long enough for a full sash window frame?
A single 1.2m length is generally used as a component piece rather than a complete frame. Most sash window projects require multiple lengths to cover the full height of each side of the frame. Measure your existing casing carefully before ordering to confirm how many lengths you need.
Can this timber casing be used in a listed building or conservation area?
Yes. A timber inner casing machined to a traditional profile is consistent with the like-for-like repair requirements typically specified by conservation officers for listed buildings and properties in conservation areas. We recommend confirming the exact profile with your local authority before ordering.
