Siniat Opal is a premium plasterboard for walls and ceilings in high-end homes. A pre-primed, heavy-duty face paper gives a smooth finish and reduces glancing light, the shadowing across joints that shows up under strong natural or angled light.

Siniat Opal’s high-density gypsum core improves sound insulation and impact resistance. It’s up to six times less prone to impact damage than standard 10mm plasterboard, which suits high-traffic areas such as stairs, corridors, rumpus rooms and kids’ playrooms, and helps the home look new for longer. On ceilings, it spans framing at up to 600mm centres.
