Acoustic Plasterboards

Acoustic Plasterboard (often called “Sound Board”) is the professional’s choice for blocking out unwanted noise. At first glance, it looks just like standard drywall, but it’s engineered to be much denser and heavier. This extra mass acts as a shield that makes it harder for sound waves to vibrate through your walls and ceilings.

If you’re tired of customers complaining they can hear the neighbor’s radio or the kids upstairs, this is your fix. It scores and snaps just like the regular stuff, so it won’t slow you down on-site, but it makes the finished room feel solid and high-end. Bottom line: it keeps the noise out and the privacy in without you having to build extra-thick walls.

FAQs

Q: Does acoustic plasterboard actually work?

A: Yes. Acoustic plasterboard significantly reduces sound transfer because it has a much higher density than standard board. When installed correctly, especially alongside acoustic insulation batts, it can block up to 75% of airborne noise like talking and TV sounds.

Q: Is acoustic plasterboard heavy?

A: Yes, it is noticeably heavier than standard plasterboard. Because it relies on high density to block sound, a standard sheet of acoustic plasterboard weighs roughly 30% to 40% more than a regular sheet of the same size, so it usually requires two people or a sheet lifter to install.

Q: How thick is acoustic plasterboard?

A: In Australia, acoustic plasterboard is most commonly available in 10mm and 13mm thicknesses. The 13mm commercial-grade sheets offer the highest level of sound reduction and are the standard choice for dedicated media rooms, inter-tenancy walls, and quiet zones.

Q: What is the difference between plasterboard and acoustic plasterboard?

A: The main difference is core density. Standard plasterboard has a lighter, aerated gypsum core designed for basic wall lining. Acoustic plasterboard features a heavily compacted, high-density gypsum core, often reinforced with fiberglass, specifically engineered to absorb and deflect sound energy.

Q: What is the best brand of acoustic plasterboard?

A: The leading, trade-trusted brands in Australia are Siniat (Soundshield) and Siniat (Createx & Creason). Both brands manufacture high-performance, fully certified acoustic sheets that meet strict Australian building standards for sound transmission loss.
