QW-SB25 Staff Bead – 25mm x 15mm Sliding Sash Window Profile

The QW-SB25 is a premium 25mm x 15mm staff bead designed for traditional timber sliding sash windows. Manufactured from Qwood’s advanced wood polymer composite (WPC), this profile combines the authentic look and feel of timber with the long-term durability and stability of an engineered material.

Widely used by joiners, sash window manufacturers and timber window specialists, the QW-SB25 is designed to provide a secure and precise internal bead for sliding sash systems. It forms part of the established Qwood sash range, trusted across both heritage restoration and modern timber window production.

Unlike traditional timber, the QW-SB25 will not rot, warp, split or suffer from knots and natural defects. This ensures consistent quality across every length, reducing waste, improving machining accuracy and delivering reliable installation performance on site or in the workshop.

The profile is supplied in straight, stable lengths and can be easily cut, machined, pinned, glued and painted using standard woodworking tools and finishing systems, making it fully compatible with existing joinery workflows.
