Reduce Impact noise

AcoustaMat Acoustic Underlay Silent Step

Reduce Footstep Noise and Floor Impact Problems

Impact noise from floors is one of the most annoying soundproofing problems, especially in apartments and multi-story buildings. Every footstep, furniture movement, or dropped object gets transmitted to the room below, creating real quality of life issues for everyone involved.

We reduce floor noise problems with acoustic underlay systems that work under any floor type – carpet, timber, tiles, or vinyl. The key is choosing the right underlay for your specific combination of subfloor (timber or concrete) and finished floor material.

Explore our complete range of soundproof products for floors, walls, ceilings, and more.

Our products can handle both impact noise (footsteps, furniture) and airborne noise (voices, music) that transmits through floors. Whether you’re building new or renovating existing floors, we have solutions that make a real difference.

Depending on your homes or Strata requirements, a layering system may be warranted to meet specific LnTw requirements. This may require the involvement of an Acoustic Engineer.

Installation and Technical Information

Professional Installation Process

Floor Underlay Installation: Proper installation is critical for acoustic performance. The key technical requirement is preventing structural transmission – finished flooring must not touch walls or skirting boards, as this creates noise transmission paths.

Installation Steps:

Subfloor assessment – evaluate condition and levelness
Underlay installation – proper edge sealing and coverage
Finished floor installation – maintain acoustic gaps at all edges
Edge sealing – acoustic sealant at perimeter gaps

Critical Installation Notes:

No contact with walls – flooring must float acoustically
Proper edge treatment – acoustic gaps must be maintained
Subfloor preparation – level, clean, and dry surface required
Professional assessment recommended for optimal results

Common Installation Mistakes:

Allowing flooring to touch walls or skirting (creates noise transmission paths)
Inadequate subfloor preparation affecting underlay performance
Incorrect underlay selection for specific floor types
Missing acoustic sealant at perimeter gaps

Subfloor Considerations

Timber Subfloors:

Assessment of joist spacing and floor stability
May require additional support for heavy floor finishes
Acoustic isolation from structural elements important
Moisture considerations for basement and ground floor applications

Concrete Subfloors:

Surface preparation and moisture testing required
Level assessment and correction if needed
Thermal bridging considerations for heated floors

Frequently Asked Questions

Which underlay should I choose for my floor type?

AcoustaMat 850RG works under any floor type – carpet, timber, tiles, or vinyl. Silent Step is specifically designed for carpet applications and provides superior performance for carpeted areas. We recommend Silent Step for carpets and AcoustaMat 850RG for hard flooring applications.

How much difference will floor underlay actually make?

Significant difference, especially for impact noise like footsteps and furniture movement. The exact improvement depends on your existing floor construction and the noise sources, but most customers notice immediate improvement in both directions – less noise from below and less transmission of your noise to below.

Can I install floor underlay myself?

AcoustaMat and Silent Step can be installed by competent DIYers, but the critical factor is proper edge treatment – the finished floor must not touch walls or skirting. This acoustic gap is essential for performance. Professional installation ensures this is done correctly.

What’s the difference between impact and airborne noise in floors?

Impact noise is footsteps, furniture movement, dropped objects – sounds created by physical contact with the floor. Airborne noise is voices, TV, music that travels through the floor structure. Our underlays address both, but impact noise is usually the bigger problem in floor applications.

Do these products meet building standards?

Yes, all our products meet relevant Australian Building Code requirements. This is particularly important for new construction and commercial applications where acoustic compliance is mandatory. We provide all necessary documentation for building approval processes.

How long do these products last?

Our floor underlays are designed for building-life durability – they’re not wear items that need replacement. They’re permanent installations designed to last as long as your flooring system.

What if I’m not sure which product I need?

Floor acoustic problems can be complex, and the wrong product won’t solve your problem. We assess your specific situation and recommend the most cost-effective solution.

Can these products be used in commercial applications?

Absolutely. All products are suitable for commercial use and meet relevant building standards. We regularly supply to builders, architects, and project managers for commercial and institutional projects requiring acoustic performance.

Will underlay affect my floor height?

Yes, any underlay adds thickness to your floor system. AcoustaMat 850RG and Silent Step are relatively thin compared to their acoustic performance, but you need to factor this into door clearances and transitions to other floors. We can help you plan for these considerations.

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.
