Over Screed Resilient Acoustic Layer & Underlay

Recent Construction methods and Environmental restrictions have increased the need for multi-occupancy buildings and noise is a very stressful but serious element of this type of the built environment and calls for extensive consideration and controls.

One of the main factors to consider with any type of flooring is the resulting acoustics in a room. Think of the difference between a carpeted room and a room with a concrete floor; the echoing sounds of concrete aren’t conducive to a warm, welcoming at-home atmosphere. While your choice of flooring plays a big part in room acoustics, the underlayment you select is just as important.

Cork has sound-dampening properties that help reduce the sound of footfalls in rooms and hallways, along with other ambient noise reduction. Installing underlay that is designed for noise reduction will take away the tension that can be caused by noise levels, which is especially important in condos, apartments, and other multi-family dwellings. Even in single homes, the ability to reduce noise transfer is important for peaceful family living, which is why cork underlay should be considered as the preferred hardwood and laminate flooring underlay.

Acousticork has solutions for different types of final flooring, including:-

  • Non Glued Laminate - T61, T66 & T85
  • Glued Down Wood - T22, T61, T66 & T85
  • Ceramic (Or Natural Stone) - T61, T66 & T85
  • LVT - T66 & T85


  • 100% Recycled Material
  • Impact Noise Reduction
  • Thermal Insulation Properties
  • High Durability and Long Term Resilience
  • High Performance with Reduced Thickness

iNSpira Sound Acoustic Underlay

Product Information

iNSpira Sound Acoustic Underlay.pdf

iNSpira Sound is a Fully Recycled Rubber Cork Resilient layer designed to absorb footfall noise and increase living standards within the construction, whether in Residential or Commercial applications. The material also has a Zero ODP (Ozone Depleting Potential) and Zero GWP (Global Warming Potential).

iNSpira Sound is an Acoustic Membrane designed for use on top of concrete floors, thereby eliminating the problems of under-screed layers which may be bridged during site installation causing expensive failures.

iNSpira Tri-Lay Acoustic Underlay

Product Information

iNSpira Tri-Lay Acoustic Underlay.pdf

iNSpira Tri-Lay  is designed for timber floor applications (but can also be used for concrete floors) that require additional airborne and impact noise insulation. This high performance composite is a sandwich laminate of two layers of WB7.5 acoustic barrier separated by a 10mm layer of cross-linked closed cell polyolefin foam.

iNSpira Tri-Lay Eco is designed for concrete floor applications (but can also be used for timber floors) that require mainly impact noise insulation and to a lesser extent, airborne noise insulation. It is a two layer laminate, the upper being  WB7.5 acoustic barrier supported by a 10mm  cross-linked closed cell polyolefin foam.


Our iNSpira Tri-Lay acoustic underlay system is an excellent under-carpet noise barrier reducing both airborne and impact noise for existing floors and is suitable for use in both commercial and residential applications, efficiently limiting the passage of noise through the floor.

Our iNSpira Tri-Lay acoustic underlay system is ideal for new, retrofit or renovation projects in offices, homes and hotel applications as it is so easy to fit.


  • Improves airborne sound insulation
  • Suitable for all final noise transmission
  • Reduces impact noise transmission
  • Tested on basic floor constructions
  • Thin, easy to handle tiles
  • Flexible and easily cut
  • Simple to install
  • Cost effective
