The perfect vinyl flooring base for impact sound insulation

Whether footfall sound insulation is necessary for click vinyl flooring depends on several factors, but in general this question can be answered with a clear “yes”.

Finally, the vinyl flooring is intended to provide the necessary calm, warmth and stability. But what about insulation in underfloor heating? How are the documents moved appropriately? And are there alternatives to the classic vinyl flooring underlay?

Why a vinyl floor impact sound insulation?

Vinyl floors can be laid floating or laid with the substrate by means of adhesive.

In the case of a floating installation, a base for the vinyl floor is also absolutely indispensable. Those who do not use suitable insulation here risk so-called walking sound, an unpleasant “clacking” while running.

In addition, the documents insulate the soil from the ground. Just as they can compensate for (light) unevenness in the underfloors without having to carry out more complex balancing work beforehand.

More features at a glance

Not only are the neighbours under one grateful for a footfall sound improvement, but also in their own rooms the room acoustics can be improved.

So the quieter the floor is when you walk, the more comfortable the room’s acoustics.

Find the right base for vinyl flooring

A footfall sound insulation for vinyl flooring is therefore indispensable. Laying the vinyl floor without a backing? Not such a good idea.

Laying a base for the vinyl floor is essential for a pleasant walking feeling and the prevention of clattering noise.

The different types of vinyl flooring documents

Relatively common are insulations made of PU heavy foam. They are made of mineral fillers and polyurethane.

The comparatively heavy rollers are best suited as vinyl flooring for underfloor heating, as they have a relatively low heat transfer resistance.

Due to their severity, there is also a significant improvement in sound values.

The polystyrene plates, a kind of styrofoam, are cheap in purchasing.

They are easy to lay, but reduce sound only moderately well. In addition, they are not suitable for underfloor heating.

Latex insulation pads also have poor heat conduction. If you don’t have underfloor heating, but still want thermally insulating properties, you could take a look at the cork material.

When can a vinyl floor be laid without footfall sound insulation?

If a vinyl floor is to be laid floating, it is imperative to insert an insulating floor between the prepared substrate and the vinyl floor.

If, on the other hand, the floor is made of solid vinyl and is to be bonded to the substrate, no additional impact sound insulation is required as a backing. In this case, the footfall sound insulation under the screed already ensures sufficient absorption of walking and impact sound.

Since the vinyl floor is connected to the screed by means of adhesive, nothing can rattle and therefore no insulation is necessary.

Old carpets as a footfall sound replacement?

An already laid carpet as vinyl flooring is not a good idea and is not approved as suitable by any vinyl floor manufacturer.

Carpets are too soft, no matter what thickness. This usually leads to excessive yielding of the soil when it is laid and entered. As a result, the click connections eleak over time and the ground comes in “movement”.

Worse still, if you put vinyl flooring on carpet, you usually forfeit the guarantee on the floor. At this point, therefore, no savings should be made!

In addition, a carpet is always susceptible to bacteria and germs when it no longer comes into direct contact with the indoor air. Therefore, unpleasant odours often occur when the old carpet has to be used as footfall sound insulation for the vinyl floor.

What footfall sound insulation for a vinyl floor on underfloor heating?

Owners of underfloor heating should pay attention to the special properties of the insulating mat used. Above all, the heat resistance and an adequate heat transmission resistance are important.

Especially with older underfloor heating systems, the material must be able to withbear the heat, as these usually become much warmer than with modern systems.

Another important feature is longevity and resistance to moisture.

Tip for purchase: The product usually shows the heat transfer resistance according to DIN 12667 in the unit m2 K/W. The lower this value, the better the forwarding of the heat.

Do you need an additional vinyl floor ingesen?

Whether at all and above all which insulation pad is needed depends on the ground. If you want to lay vinyl floor floating on a screed, you need a so-called steam brake.

These can be purchased in the form of a PE film and protects the soil from rising moisture from the substrate or underlying wet rooms.

In the end, the moisture could cause considerable damage to the material.

Vinyl floor footfall sound insulation laid

One click vinyl floor ingesency is relatively easy to lay. Especially if the ground has no major bumps.

If this is the case, unevenness must first be levelled with a cemented compensating mass. Otherwise, cleaning with a brace and vacuum cleaner is part of the preparation.

Subsequently, the impact sound insulation is rolled out by way of track. It is important to start on the longitudinal wall and always work in parallel. The individual tracks must not overlap, as this can later lead to unevenness in the ground. In this context, we are talking about a ‘shock-to-shock installation’.

In order to make it easier to lay the insulating satellites, the webs can be fixed to the ground on a point-by-point basis. Now all other lanes follow. At the longitudinal thrusts, the webs can be easily connected with adhesive tape.
