Barrierboard Acoustic Wall Systems Barrier Systems Soundproof Pipe Solutions Stratocell Whisper

Reduce Noise Getting Through Your Walls

Walls are often overlooked when people think about soundproofing, but they’re crucial for creating quiet spaces. Whether it’s noisy neighbours, traffic, industrial noise, or just wanting privacy between rooms – our wall soundproofing solutions make a real difference.

We offer two main barrier solutions: Barrierboard for structural wall soundproofing that can reduce noise by up to 90%, and barrier materials like Wavebar. Both products are Australian made and designed for our conditions. Barrierboard is a composite panel system that replaces or adds to standard plasterboard.

In addition, Stratocell Whisper, is a revolutionary low density closed-cell polyethylene metamaterial foam acoustic sheet, which can be fitted to walls for sound absorption that eliminates echo and reverberation. It has the highest possible Noise Reduction Coefficient (NRC) rating of 1.0, and a Transmission Loss (TL) performance of 13.8dB,

Stratocell Whisper is designed for both indoor and outdoor noise absorption.

Each product targets different acoustic problems and can be used together for maximum effectiveness.

Pipe wrap is also available to reduce noise via water and waste pipes within walls.

Our Wall Barrier Products

Barrierboard Acoustic Wall Systems

Complete Wall Soundproofing Solution

Barrierboard is a composite panel comprising two layers of plasterboard with an acoustic isolation layer sandwiched between them. This patented Australian product provides serious noise reduction in a single, easy-to-install panel.

How Barrierboard Works:

Sound passes through the first plasterboard layer, then decoupled by the isolation layer,resulting in minimal energy left to pass through the final layer. The result is dramatic noise reduction – up to 90% depending on wall construction type…

Key Features:

Composite construction: two plasterboard layers with acoustic core
Rigid panels: no sagging or bowing like standard plasterboard
Overlapping design: panels are rebated for continuous acoustic seal
Dense construction: 32mm thick but much denser than standard materials
Easy installation: about 50% faster than traditional systems
Versatile fixing: can be applied directly to walls or over furring channels

Installation Options:

Direct fix: straight onto existing walls, 32mm depth loss
Furring channel system: allows additional insulation, 60-64mm depth loss
New construction: replaces standard plasterboard in wall systems
Retrofit applications: can be applied over any structurally sound wall

Performance Applications:

Residential: between apartments, townhouses, bedrooms, home theatres
Commercial: office partitions, conference rooms, music studios
Industrial: plant room walls, factory office separation

Frequently Asked Questions

How much noise reduction will I actually get with Barrierboard?

Barrierboard alone typically provides around 75% noise reduction depending on your existing wall construction. Complete Barrierboard wall systems can achieve up to 90% reduction with proper installation. The exact improvement depends on your current wall type and the noise sources you’re dealing with.

Can I install Barrierboard myself?

Yes, competent DIYers can install Barrierboard following our detailed instructions. However, for Building Code compliance or large commercial projects, we recommend professional installation. The panels are heavier than standard plasterboard, so you’ll need appropriate lifting help.

Will pipe wrap work on my existing plumbing?

NuWrap 5 can be applied to accessible existing pipes. The challenge is often access – pipes inside walls or under slabs are difficult to treat. We assess your specific situation and recommend the most practical approach for your pipe noise problems.

Customer Feedback

We just had our double glazed windows installed by Luca at Soundblock in our bedrooms and he was an absolutely pleasure to deal with. Very professional and friendly and the price quoted was very reasonable. Free measure and quote who they responded within 24 hours. Micheal came out and provided his honest opinion and was very transparent as we live on a busy road in Randwick. The service provided by Soundblock was second to none. I would definitely recommend Soundblock to family and friends. Well worth the investment with the difference in noise reduction.

Peter N

Very professional sound “sound” advice and service. We were kept informed of the progress of our order and the installers were extremely proficient and showed they enjoyed their work.
