QW-OB19 Ovolo Bar – 19mm x 16mm Composite Glazing Bar

The QW-OB19 Ovolo Bar is a high-performance composite glazing bar from the Qwood range by Quantum Profile Systems. Designed specifically for timber windows and doors, it combines traditional ovolo detailing with the durability and consistency of modern wood polymer composite (WPC) technology.

Engineered for excellent dimensional stability and long-term performance, the QW-OB19 profile provides a reliable alternative to traditional timber glazing bars while maintaining an authentic heritage appearance. The 19mm x 16mm section makes it ideal for slimmer glazing bar designs used in both refurbishment and new-build timber window applications.

Traditional Ovolo Detailing with Modern Composite Performance

The QW-OB19 profile features a classic ovolo design that replicates the appearance of traditional timber glazing bars commonly used in period and heritage-style windows. It allows manufacturers and joiners to retain authentic aesthetics while incorporating modern double glazing systems.

Unlike natural timber, Qwood composite profiles are manufactured to provide consistent quality without knots, imperfections, or excessive movement. This helps improve machining accuracy, reduce waste, and support more efficient production processes.
