QW-SDA2 Ovolo Bar – Composite Glazing Bar for Timber Windows & Doors

The QW-SDA2 Ovolo Bar is a high-performance composite glazing bar from the Qwood range by Quantum Profile Systems. Designed for use in timber windows and doors, it combines traditional ovolo styling with the durability, stability, and consistency of modern wood polymer composite (WPC) technology.

Manufactured specifically for the timber joinery industry, the QW-SDA2 profile provides an excellent alternative to traditional timber glazing bars while maintaining the authentic appearance required for heritage, conservation, and high-end residential applications.

Traditional Ovolo Styling with Enhanced Durability

The QW-SDA2 profile features a classic ovolo moulding detail designed to replicate traditional timber glazing bars used in period and heritage-style windows. The larger 24mm x 16mm section creates a more substantial sightline, making it ideal for applications where stronger visual detailing is required.

Unlike natural timber, Qwood composite profiles are engineered to remain continually straight and dimensionally stable, helping to reduce waste, improve machining accuracy, and minimise movement over time.
