Frequently Asked Questions

  • What types of plasterboard are available for different rooms?

    There are several types of plasterboard designed for specific conditions. Standard plasterboard is ideal for living spaces, while moisture-resistant sheets are best for bathrooms and kitchens. Fire-rated options are available for garages or commercial spaces, and acoustic plasterboard helps reduce sound between rooms. Using the right type ensures durability and compliance with building standards.

  • Why choose Siniat plasterboard for my project?

    Siniat plasterboard is known for its quality, reliability and ease of installation. It’s designed to meet Australian Standards and comes in a variety of specifications to suit both residential and commercial builds. The brand’s system-based approach means every product — from sheets to adhesives — is made to work together for a consistent, professional result.

  • Can plasterboard improve insulation and soundproofing?

    Yes. Many plasterboard systems include insulation layers that improve thermal performance and sound control. Acoustic plasterboard, for example, uses denser cores to reduce noise transfer between rooms. Pairing it with proper insulation materials helps make homes and offices more energy-efficient and comfortable year-round.
