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.

Discover our comprehensive range of soundproof products for complete acoustic control.

In addition, Stratocell Whisper panels can be fitted to walls for sound absorption that eliminates echo and reverberation.

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

Barrierboard is a composite panel system that replaces or adds to standard plasterboard, while Stratocell Whisper is a foam panel system perfect for both indoor and outdoor noise absorption. Each targets different acoustic problems and can be used together for maximum effectiveness.

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
Institutional: hospitals, schools, government buildings

Typical Noise Reduction:

Around 75% noise reduction with Barrierboard alone (depending on existing wall construction). Higher performance possible with optimised wall systems and additional treatments.

Both products are designed for building-life durability. Barrierboard performs like quality plasterboard with added acoustic properties. Stratocell Whisper is resistant to weather, chemicals, and physical damage. We don’t expect degradation in normal building applications.

Can these products be used together?

Absolutely. Barrierboard provides structural noise reduction through walls, while Stratocell Whisper absorbs sound within rooms to reduce echo and reverberation. Using both creates comprehensive acoustic treatment for demanding applications.

Do these products meet Australian building standards?

Yes, Barrierboard systems are specifically designed to meet or exceed Building Code of Australia sound insulation requirements. Stratocell Whisper meets relevant fire and safety standards for both indoor and outdoor applications.

What about fire safety?

Both products have appropriate fire ratings. Barrierboard includes standard plasterboard fire protection. Stratocell Whisper has Group 1 fire rating (FR version) or self-extinguishing properties (UV version). All relevant safety documentation available.

Can I paint or decorate over these products?

Barrierboard finishes exactly like standard plasterboard – you can paint, wallpaper, or apply any standard wall finishes. Stratocell Whisper is available in white, grey or black for indoor applications. Available in glossy grey and black for outdoor applications.

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.
