A footfall sound insulation makes your home more quiet. No more loud footsteps.

Insulation underlays - Comfort with every step

Be kind to your ears, joints and spine – with the Silent Pro luxury insulation underlay

For all those wanting to treat themselves to a little more comfort, insulation underlays are a must. Thanks to their slightly springy resilience they are not only kind to the ears, joints and spine, but also minimise footfall and room sound – which will not only please you but also your neighbours. For all HARO three-layer floors, Silent Pro luxury insulation underlays are optionally available either in rolls or factory-bonded to the board underside. Your local HARO dealer will be happy to assist you.

Integrated insulation layers
The integrated Silent Pro insulation layer is factory-bonded to the underside of the parquet board to create a permanent connection between board and insulation. Positive effect: possible voids or gaps are closed, which increases the acoustic insulating effect. Because gaps cause hollow, loud sounds when walking on the floor, they impair the actual acoustic insulating effect concerning the indoor sound. Another advantage of the integrated layer is that insulation and installation can be done in a single work step.

Insulation underlays
We recommend an insulation underlay for all hard subfloors. It helps to increase the resilience of the floor, absorb footfall and room sound, and even out minor irregularities of the subfloor. Your neighbour’s ears and your parquet will be really happy with the result.

Pleasant for you when the sound level in the room is perceptibly minimised.

Reduce the indoor sound by up to 30% with suitable footfall sound insulation.



It will especially please your neighbours when your steps do not sound like thunder.
