Concrete floor Soundproofing Solutions

Due to the high mass/density of concrete floors, floor soundproofing solutions will predominantly help to reduce impact sounds through concert flooring.

Noisestop Acoustic Underlay 12mm

Noisestop Acoustic Underlay has been designed to reduce the impact sound through concrete floors. Features closed cell foam and mass loaded vinyl to cushion footfall and movement noise that would typically transfer through concrete flooring.

  • System thickness 12mm 
  • Impact noise reduction 47dB (lower the better)
  • Part E compliant
  • Cost approx. £22.19sqm plus VAT

Noisestp Impact Mat

This slim, soundproof membrane from 90% recycled materials reduces impact sounds through concrete flooring. Lay the mats below any floor finish without needing a resilient layer, including below tiled flooring, wooden floors and vinyl,

  • System thickness 3mm to 5mm 
  • Impact noise reduction 55dB
  • Part E compliant
  • Robust detail-compliant E-FC-1 and E-FC-2


Concretedeck 18mm, 23mm, and 27mm consist of a 5.5 mm layer of cross-linked Isopoli bonded to 22mm, 18mm and 12mm P5 V313 moisture-resistant chipboard. Enables a concrete floor to meet the sound transmission standards of Approved Document E 2003 and subsequent amendments in 2004, 2010, 2013 and 2015

  • System thickness 18mm 23mm & 27mm
  • Impact noise reduction
  • Part E compliant

Soundproofing Floors FAQs

Impact noise through floors refers to the sounds generated by impact or physical contact on a floor surface that transmits to the space below. This could be footsteps, dropping objects, dragging furniture, or any action that causes vibrations and sound transmission through the floor’s structure.

Soundproofing materials, acoustic underlays, and floating flooring options are used to reduce the impact noise that travels between floors. Our Noisestop F7 Plus and Noisestop Acoustic Underlay are the best soundproof mats. The Noisedeck range of interlocking floating floors includes the Noisedeck 32, a direct to joist system and the Noisedeck 18T, a floor overlay system.

Installing soundproofing to the floor will give you the best results in reducing impact noise. However, ceiling solutions are also available to reduce impact noise from below.

Airborne noise refers to sound that travels through the air, like voices, music, or TV noise. To soundproof against airborne noise, you add mass and absorption materials to the floor.

Materials such as acoustic insulation and soundproof mats all help reduce airborne sound transfer between floors. The Noisestop F7 Plus is our highest performing acoustic underlay. Acoustic insulation DFM 100mm between floor joists is another way of increasing the mass and absorption of wooden floors.

You can lay the carpet directly onto acoustic underlays. You might use them in conjunction with a traditional carpet underlay for added comfort.

If the flooring you are using is below 14mm thick and you are using one of the acoustic underlays, you would need to use a resilient layer over the soundproofing to support the floor finish. Flooring over 14mm, such as engineered flooring and natural wooden floors, can be laid directly over the underlays.

Interlocking floors in the Noisedeck range already have a suitable base for any floor finish, so they do not require further treatment.

When installing soundproofing for your floors in these spaces, avoid directly placing kitchen units, baths, sinks, or toilets onto the soundproofing. To maintain consistent floor heights, employ a plinth beneath these items to ensure everything stays at the proper level.

Essential Soundproofing Rules

Achieve the very best floor soundproofing results by following these essential soundproofing rules. These are adding mass/density to the area, isolating or decoupling the new structure from the existing and increasing sound absorption. These rules of soundproofing apply whether you are attempting to soundproof a wooden floor or a concrete floor. Increasing mass makes it harder for the sound to transfer. The variety of high-mass products will block a great range of sounds. Isolating the structure will reduce sound as it vibrates through a solid structure. Increasing absorption allows the floor to absorb the sound energy. These soundproofing principles are built into the design and specification of our floor soundproofing products and systems.


Adding mass/density to an area blocks sound transfer. Using materials with different densities will reduce a greater range of frequencies.


Creating isolation or decoupling the existing structure from the new enhances sound insulation.


Increase sound absorption with materials that absorb sound waves and reduce the energy that carries the sound.
