QW-GB5A – PUSH ON GLAZING BEAD works with the QW-GB5A clip

QW-GB5A Push-On Glazing Bead – Composite Bead for Timber Window Systems

The QW-GB5A Push-On Glazing Bead is a high-performance composite glazing bead from the Qwood range by Quantum Profile Systems. Designed for timber window systems, the profile provides a fast, secure, and efficient glazing solution while maintaining the traditional appearance of timber joinery.

Manufactured using advanced wood polymer composite (WPC) technology, the QW-GB5A combines the appearance and machinability of timber with the durability, stability, and low-maintenance benefits of engineered composite materials. It is specifically designed for use with the Qwood push-on glazing clip system for fast and consistent installation.

Designed for Push-On Glazing Systems

The QW-GB5A is engineered to work with the QW-GCA1 glazing bead clip system, creating a secure push-fit glazing solution for timber windows. The system is designed to simplify installation while improving drainage and ventilation around the glazing unit.

Unlike traditional timber glazing beads that require pinning or extensive finishing, the Qwood push-on system provides a cleaner installation process and helps reduce manufacturing and fitting time.
