Glancing refers to light being cast along the face of a surface showing any minute undulation. As a result of this light being cast, a shadow is produced on the other side of the undulation.

This draws attention to surface texture variations, such as plasterboard joints and patches, which under more diffused light would not be visible.

Opal plasterboard has the added benefit of being a certified carbon neutral product that can help reduce the embodied carbon of the build.

Siniat offers the Opt2Act opt-in carbon neutral program on a wide range of plasterboard and metal products. The specific products opted-in are certified by the Australian Government’s Climate Active as Carbon Neutral.

Opal is certified carbon neutral by Climate Active in its own right, which means that customers do not have to opt-in; Opal comes carbon neutral as standard. It is also certified by Global GreenTag to GreenRate Level A. 

Opal’s high-density gypsum core delivers enhanced sound insulation for superior acoustic comfort that creates a peaceful indoor environment.

The denser core further improves its impact resistance; Opal is up to six times less prone to impact damage compared to standard 10mm plasterboard. This adds durability to high-traffic areas such as stairs, corridors and rumpus and children’s playrooms.
