Pine parting bead 8mm x 21mm x 2400mm is the slender timber strip that separates the inner and outer sashes in a traditional box sash window, keeping both sashes running true within their channels. Machined from straight-grained softwood pine, it is a direct, cost-effective replacement for worn or missing beads in period and modern timber window frames.
Specifications
| Property | Detail |
|---|---|
| Material | Softwood pine |
| Finish | Machined, ready to prime or paint |
| Nominal Size | 8mm x 21mm |
| Length | 2400mm |
| Profile | Parting bead (flat, rectangular section) |
What it's used for
- Separating the inner and outer sashes in traditional box sash windows, holding each sash in its own running channel
- Replacement parting bead in period timber window frames where the original bead has split, swollen, or gone missing
- New-build or renovation sash window joinery where correctly profiled timber mouldings are required
- General glazing bead duties in purpose-made timber frames where an 8mm x 21mm section is specified
Fitting and handling
Allow the bead to acclimatise inside the property for at least 48 hours before fitting, particularly in older properties with higher humidity, to reduce the risk of swelling after installation. Fix with panel pins or a suitable timber adhesive, ensuring the face is flush with the frame rebate so the sashes slide freely without binding. Apply a coat of primer or wood paint to all faces before and after fitting to protect the softwood from moisture ingress and to match your existing window frame finish.
FAQ
What is parting bead used for in a sash window?
Parting bead sits in a groove between the inner and outer sashes of a box sash window. It acts as a physical divider that keeps each sash in its own channel, allowing both to slide up and down independently without rubbing against each other.
Can I use this parting bead on a softwood sash window repair?
Yes. This 8mm x 21mm pine parting bead is the standard section used in the majority of traditional softwood box sash window frames across the UK. Check the width of your existing parting bead groove before ordering to confirm it matches the 8mm thickness.
Does pine parting bead need treating before fitting?
Pine is a softwood that will absorb moisture if left untreated, which can cause it to swell and prevent the sashes from sliding. Prime or paint all faces, including the back face that sits in the groove, before and after installation to protect the timber and extend its service life.
