QW-SB20NI Staff Bead – 20mm x 15mm Non-Integrated Sliding Sash Profile

The QW-SB20NI is a high-performance non-integrated staff bead designed for traditional timber sliding sash windows. Manufactured from Qwood’s advanced wood polymer composite (WPC), this 20mm x 15mm profile delivers the authentic look of timber with the stability, durability and consistency of a modern engineered material.

Designed for joiners, sash window manufacturers and timber window fabricators, the QW-SB20NI provides a reliable, low-maintenance alternative to traditional timber staff beads. Its non-integrated design allows flexibility within sash window systems while maintaining compatibility with standard timber detailing and draught sealing solutions.

Unlike timber, Qwood composite profiles are engineered to remain stable in service. The QW-SB20NI will not rot, warp, split or suffer from knots, helping to reduce waste, improve manufacturing efficiency and extend the lifespan of finished windows. Consistent straight lengths ensure accurate machining and faster installation.

The profile can be cut, machined, pinned, glued and painted using standard woodworking tools and finishes, making it easy to integrate into existing production processes without specialist equipment or additional training.
