Floor Impact Isolation Pads

Product Overview

(Resilient Underlay for Footfall and Structural Vibration Control)

Floor Impact Isolation Pads are engineered composite layers made of resilient rubber, closed-cell foam, or hybrid materials designed to minimise impact sound transmission through floors. These pads are a key solution for achieving acoustic comfort in multi-storey buildings, particularly where impact noise (e.g. footsteps, dropped objects, furniture drag) travels between levels.

Key Features

• Impact Noise Reduction

  • Specifically targets low-frequency impact sound that travels through floor structures

  • Reduces Ln,w (weighted impact sound pressure level) as per ISO 717-2 and AS/NZS standards

  • Helps meet NZ Building Code Clause G6 for sound transmission between tenancies

• Material Composition

     Typically made from:

• • Recycled rubber granulate, bonded with PU binder

  • Cross-linked PE/EVA foam layers

  • High-density elastomeric mats

  • Available in rolls, tiles, or cut pads of various thickness and density

• High Load-Bearing Capacity

  • Engineered to support loads under screed, tile, timber, or floating floor systems

  • Maintains resilience under compression without permanent deformation

• Moisture & Chemical Resistance

  • Closed-cell and elastomeric options resist water absorption and are mould-resistant

  • Compatible with underfloor heating systems and wet area substrates

• Installation Ease

  • Can be installed as continuous underlayment or discrete pad layouts

  • Some variants include adhesive backing or geotextile facings for quick installation
    
    

Product Variants

• Thickness Range: 3 mm to 15 mm (depending on system)

• Formats: Roll form (~10–20 sqm per roll), tile/pad form (~1 m² units)

• Acoustic Ratings: ΔLw (impact improvement index) of up to 25 dB (varies by system)

• Compatibility: Suitable under tiles, screeds, laminates, engineered wood, vinyl flooring
  
  

Common Applications

1. Multi-level Apartments and Townhouses

Between floors to reduce tenant-to-tenant footfall noise

2. Hospitals, Aged-Care Facilities & Hotels

Improves privacy and comfort in sleep and recovery areas

3. Office Buildings & Retail Spaces

Used under raised access floors or floating timber finishes

4. Cinemas & Studios (Floating Floors)

Part of multi-layer acoustic floor assemblies

Compliance & Standards

• AS/NZS 2107 – Recommended design sound levels and reverberation times

• ISO 140-8 / ISO 10140-3 / ISO 717-2 – Impact sound insulation testing

• VOC Emissions – Many variants are Green Star or Homestar compatible

• Non-toxic and recyclable variants available
