Acoustic Properties:

Amongst other features that need to be considered when constructing residential or commercial structures, one of the most important are the acoustic properties. The design of flooring within buildings is now integral to achieving a sound-proof layer between one floor and another, and ensures a resident or occupier is not interrupted by noise above or below. But, how does it work?

Here at Marldon we have honed this very technique within our own flooring materials, utilising our own timber, Marldon adhesive, concrete and other layers that work together to achieve the best sound proofing in the smallest space possible. Below we outline the many circumstances where it is required, exactly how it works and the materials required to achieve it.

How It Works:

The construction of a floor can be changed in certain key ways to improve the acoustic qualities and to stop any excessive noise travelling through. In fact, there are two direct techniques that contribute to soundproofing; Noise Absorption and Noise Dampening.

By using certain materials such as rubber or an equivalent, noise can be absorbed, soaked up effectively by a surface that doesn’t necessarily allow sound to bounce off as easily as wood or glass. The layers that are therefore used underneath timber flooring need to lend themselves to absorbing sound as effectively as possible.

Noise Dampening, on the other hand, is the use of material that is solid enough that it won’t transmit sound vibrations through it, stopping the noise from travelling through completely. The most obvious material to use is concrete, but there are other ways to also achieve this dampening, and to ensure that the flooring is dense enough that it will not let any sound waves travel through.

Picture above: Flooring build up that incorporates underfloor heating and superb acoustic properties

The top layer is Havwoods timber flooring, a choice between the Pure Plank, Venture Plank and Plus Floor Flooring ranges

  •      Next is a Marldon MXA200 bonding adhesive
  •      Directly underneath is a layer of Strata 4515, which is a PUR foam/cork compound with exceptional acoustic properties, performing the role of noise absorption in the structure
  •      Then, a Marldon MXS140 breathable membrane
  •      After that, a level of screed is used to level out the structure
  •      Underfloor heating (optional)
  •      Thermal Insulation
  •      Concrete provides the noise dampening properties that are required for effective soundproofing
