Renowned for its pioneering work in the field of sustainability, Siniat supplies an array of quality wall and ceiling solutions to the residential sector.

HIA content team


Siniat wall and ceiling solutions are trusted in Australia for its quality and performance, and the brand is a well-established market leader in the lightweight construction industry. It’s also well known for its pioneering work in the field of sustainability.

The Siniat brand is part of Etex, a Belgium-based global leader in lightweight construction solutions. In Australia, Siniat products are manufactured by Etex Australia in its factories in Bundaberg, QLD (plasterboard); Matraville, NSW (plasterboard); Altona, VIC (plasterboard and compounds) and Beenleigh, QLD (metal).

Etex Australia prioritises safety, quality and sustainability in the manufacturing process. All its manufacturing and distribution facilities are certified to the most current versions of the ISO management system standards for health and safety, quality and environmental management.

Siniat believes in the robust testing of its products, enabling the brand to offer solutions that comply with current building codes and standards.

Siniat’s solutions are supplied through a national distribution network comprising company-owned stores, Plastamasta outlets and other independent distributors.

Siniat supplies a wide range of standard and specialty plasterboard to the residential sector. The range includes fire-resistant boards such as Fireshield and Multishield, and water-resistant Watershield for wet areas. Other products such as Curveshield make attractive design options a reality. Opal is a premium plasterboard specifically designed for high-end residential projects.

Locally made plasterboards are available under Siniat’s Opt2Act® opt-in carbon-neutral program. Currently, Siniat is the only Australian plasterboard and metal manufacturer to offer a carbon-neutral program of this kind. Opted-in products supplied under the program are certified carbon-neutral by the government’s Climate Active program. By choosing carbon neutral, designers and builders can significantly reduce the embodied carbon of the build.

Locally made plasterboard products have also been independently certified by Global GreenTag to GreenRate Level A.

By investing in certified products, designers, builders and homeowners can be rest assured they’re making sustainable product choices that conform with the standards of recognised third-party certifiers.

Plasterboard has other inherent sustainable qualities, including being a lightweight building material that means lower transportation cost. It’s also 100 per cent recyclable and, at end-of-life, can be fully diverted from landfill. Siniat encourages the recycling of plasterboard and provides a list of plasterboard waste collection services and recycling facilities throughout Australia on its website.


Opal plasterboard by Siniat is a unique product specifically made with the discerning homeowner in mind. Suitable for walls and ceilings, it comes with a pre-primed surface liner paper that creates a smooth, premium surface finish that adds an elegant touch to any project. The smooth finish helps to reduce glancing light issues for a polished look and feel.

Another benefit of this premium product is a denser gypsum core for improved acoustics and impact resistance. Enhanced acoustics create a more comfortable indoor environment, especially in busy households where children’s noisy activities may interfere with the quiet space required by a parent working from home.

The improved impact resistance will appeal to property owners building their forever home, or an investor needing added durability. It results in walls and ceilings that can beautifully withstand the knocks of everyday life, adding durability to the home and making that ‘new home’ feeling last longer.

An added bonus is that Opal comes carbon neutral as standard. This means there’s no need to opt-in.

Weather Defence®

Weather Defence® is a rigid air barrier board supplied by Siniat that is commonly used behind facade cladding systems in ventilated facades. It also has a residential application for homes built in bushfire zones.

In the construction of homes located in the most fire-prone areas defined as BAL-FZ, Weather Defence can be used in the roof system to help protect the building against radiation in the event of a fire.

The system complies with AS 3959:2018: Construction of buildings in bushfire-prone areas.

Another benefit of this application is that Weather Defence can be left exposed to the weather for up to 12 months, protecting the structure during construction.

Contact the Siniat Technical Team for more information about this application.


For the construction of adjoining residential dwellings such as duplexes or townhouses, Siniat offers the tried-and-trusted Interhome separating wall system. It’s offered as a complete system, inclusive of metal, plasterboard and compounds.

Interhome is differentiated from conventional double stud separating walls by its central fire barrier built between timber or steel house frames. This central fire barrier helps to prevent the spread of fire from one dwelling to the adjoining ones.

Siniat’s Shaftliner or Intershield is used in the construction of the central fire barrier, and being gypsum-based, it makes the installation of penetrations for services much safer and quicker.

Intershield has the added advantage of mould resistance, which can be a real timesaver on site. Mould often forms on interstitial structures during construction before the building is roofed over. When this occurs, builders must wait for the structure to dry and the mould to be cleaned off before construction can continue.

Siniat recommends using mould-resistant Multishield in the lamination of the central fire barrier for the best protection against mould.

Visit Siniat to find out more about its range of products or how Siniat can provide technical assistance in your next residential build.
