Siniat Opal is a heavy-duty, high-performance plasterboard designed to give Australian homes a premium finish that actually lasts. Built with a high-density core, it is up to six times more impact-resistant than standard 10mm board and provides superior sound insulation for a quieter indoor environment. The pre-primed surface liner is a game-changer for large, sun-drenched living areas, as it creates a dead-flat finish that hides imperfections and minimizes glancing light issues. It’s tough enough for hallways and kids’ playrooms, flexible enough to span 600mm ceiling centers, and is fully carbon neutral and GreenTag Level A certified, making it the reliable choice for builders who want a durable, eco-friendly, and trade-quality result.
