GTEK™ has been rebranded as Siniat in Australia.
In 2023, Etex Group, a global building materials manufacturer, acquired BGC’s plasterboard and fibre cement businesses, which included the GTEK™ plasterboard range. Following this acquisition, the GTEK™ brand has been integrated into Etex’s Siniat brand portfolio.
This rebranding means that products previously known under the GTEK™ name are now available under the Siniat brand in Australia. The transition reflects Etex’s strategy to unify its plasterboard offerings under the Siniat brand, providing customers with a consistent range of high-quality building solutions.
Siniat’s standard board is a plasterboard made of gypsum and is primarily used for partitions, linings and ceilings. It’s also suitable for tape and jointing or skimming. There are varying sizes available, all with the option to have their edges squared or tapered.
Siniat offers a wide variety of cost-effective plasterboard products that can meet any of your needs. Contact us for more details so we can better assist you with your construction plan and budget.
The choice is dependent on your needs and preferences.
Plasterboard is easy to install, relatively cheaper, lightweight, and ready to paint. On the other hand, wet plaster is easier to mould for complicated designs and can be quite durable if applied properly. However, it can cost a bit more and is labour-intensive to install.
Installing plasterboards is quite easy. Check out our dedicated guide to plasterboard installation for a better understanding to get you started on your next project!
Fire ratings for Siniat’s plasterboards come in a wide range for every possibility. The best plasterboard option for fire resistance is the Siniat Fireshield, which can provide a Fire Resistance Level (FRL) of up to 240 minutes. Contact us for more details and browse our stock.
If you’re looking for water-resistant options, Siniat offers Watershield plasterboards, specifically designed to be resistant to water damage and can be used for kitchens and bathrooms.
Yes, technically in the Australian market, Knauf and Siniat are the same—since Knauf was rebranded to Siniat in 2021.
Etex took over Knauf’s Australian plasterboard operations, and all Knauf products are now sold under the Siniat name. The systems, specs, and performance remain the same, just with updated branding.
So if you’re looking for a former Knauf product or system in Australia, you’ll now find it in the Siniat range.
