More Information
HARO Insulation Underlay Silent Pro DS 3 mm Comfort-LineThis

acoustic mat was

specially developed for floating installation under parquet or laminate flooring.

Due to its high dead weight, this insulation mat achieves very good values in terms of footfall and impact sound reduction. The structure of the acoustic mat results in a "forest floor effect", which is easy on the spine and joints of the user. Due to its very low thermal resistance and integrated moisture barrier, this insulation mat can be laid well over underfloor heating systems carrying hot water

How is this insulation underlay constructed?

This permanently elastic acoustic insulation mat consists mainly of quartz sand and polyurethane binders. On one side of the insulation mat a fleece is laminated, on the other side a vapour barrier made of aluminium.

Is this acoustic mat environmentally friendly?

The acoustic mat is both harmless to health and environmentally friendly. The TÜV has tested it for harmful substances and declared it toxicologically safe. It is free of heavy metals, plasticizers, formaldehyde and asbestos. It is manufactured without CFCs, solvents or ozone-depleting substances. At the end of its useful life, this acoustic mat can be recycled or disposed of in household waste

Where can this acoustic mat be used?
This acoustic mat is suitable for installation:
  • on mineral subfloors, for example screed or concrete
  • over water-bearing floor heating systems
  • under laminate flooring that is laid as a floating installation
  • under solid wood parquet with floating installation
  • under finished parquet flooring with floating installation
Due to the integrated moisture barrier, this acoustic mat should not be installed on wooden floors. This moisture barrier prevents the wooden floor from releasing moisture. This poses the risk of mould growth on the wood.
How is the HARO Silent Pro DS Comfort-Line acoustic underlay installed?

Unroll the acoustic mat with the aluminium side facing upwards. Use a cutter knife to cut the strips conveniently and dust-free. Lay the strips butt to butt and tape the joints with aluminium adhesive tape to obtain a continuous moisture barrier.
