New dBack Acoustic Carpet Backing Offers Improved Sound Absorption

Heritage Carpets continues to provide innovative and relevant flooring solutions for the education sector with the introduction of Modulyss dBack Acoustic Backing. The dBack Acoustic Backing system is composed of:

  • Top layer: The pile material, primary backing and pre-coat (latex)
  • Middle layer: Bitumen
  • Base layer: dBack recycled polyester felt

This careful combination of textiles offers improved impact noise and sound absorption and is also kinder on the environment.

Acoustic Properties

dBack Acoustic Backing meets the acoustic requirements for learning spaces as outlined in the Design and Quality Learning Spaces Document (DQLS) provided by the Ministry of Education.

The extensive testing data available on the dBack Acoustic Backing documents demonstrates how relevant this product is for controlling reverberation, sound insulation, impact sound and ambient noise. Compared with Modulyss' 100% bitumen back2back, dBack provides a minimum improvement of 50% in sound absorption. This has been achieved by replacing a cover fleece of 85g, with the far-denser 800g dBack recycled polyester felt.


Modulyss has a number of class 33 products, giving them a heavy commercial rating. All Modulyss commercial carpet tiles come with a robust 15 year commercial warranty.


Choosing Nylon products means that they are resilient (won't crush), while solution dyed material means that the colour is impregnated in the yarn rather than applied to the yarn by printing or other methods. What this means is that the colour can't fade and stains and marks can't penetrate the fibre.
