QW-OB1 Ovolo Bar – 22mm x 12.5mm Composite Glazing Bar

The QW-OB1 Ovolo Bar is a high-performance composite glazing bar from the Qwood range by Quantum Profile Systems. Designed for timber windows and doors, it combines the traditional appearance of timber glazing bars with the long-term durability and consistency of wood polymer composite (WPC) technology.

Manufactured to provide excellent dimensional stability and machining consistency, the QW-OB1 profile is ideal for both modern timber window manufacturing and heritage refurbishment projects where authentic detailing is essential.

Traditional Ovolo Styling with Modern Performance

The QW-OB1 features a classic ovolo profile designed to replicate traditional timber glazing bars used in period and heritage-style windows. It allows manufacturers and joiners to retain authentic window aesthetics while incorporating modern double glazing systems.

Unlike traditional timber glazing bars, Qwood composite profiles are engineered to remain consistently straight and stable, helping to reduce waste, improve machining accuracy, and minimise installation issues.
