QW-SB21NI Staff Bead Clip-In Non-Integrated – 21mm x 20mm Sliding Sash Profile

The QW-SB21NI is a high-performance clip-in non-integrated staff bead designed specifically for traditional and modern timber sliding sash windows. Manufactured from advanced Qwood wood polymer composite (WPC), this 21mm x 20mm profile delivers the classic appearance of timber with the long-term durability and consistency of a modern engineered material.

Developed for joiners, timber window manufacturers and sash window fabricators, the QW-SB21NI provides a reliable and low-maintenance alternative to traditional timber staff beads. The clip-in design supports efficient installation and maintenance, while the non-integrated profile offers greater flexibility when selecting draught seals and sash window components.

Unlike timber alternatives, Qwood staff beads will not warp, rot, split or suffer from knots and imperfections. Every length is manufactured to deliver excellent dimensional stability and straightness, helping reduce waste, improve machining efficiency and streamline production processes.

The QW-SB21NI can be cut, pinned, machined and painted using standard woodworking tools and finishing systems, making it easy to integrate into existing timber window manufacturing processes. Its durable composite construction also helps improve long-term sash window performance while reducing ongoing maintenance requirements.
