Right Impact Sound Insulation for Your Vinyl Floor

If you have chosen a vinyl floor, a footfall sound insulation is usually also indispensable. Especially when floating, you must not do without it. Sound insulation is an important component of high-quality construction and should not be neglected. In our article you will learn everything about footfall sound, the different insulation materials and which impact sound insulation is right for you.

 

  1. What is footfall sound?

We understand footfall sound as the transmission of sounds caused by the movements of humans or animals on a floor. Walking sound, on the other hand, refers to the transmission of noise through the air within the room. These shells occur more frequently in loose lay vinyl floors, as a cavity is created between the flooring and the substrate. It additionally reinforces the two types of sound. While this phenomenon hardly occurs with fully glued vinyl, a footfall sound insulation is therefore indispensable for floating lyre-laid vinyl floors.

 

  1. Why does your vinyl floor need impact sound insulation?

During a floating installation, your vinyl floor is not fixed to the substrate. This can cause a rattling noise due to direct contact with the underbody. The footy sound acts downwards, the walking sound is then usually perceived as an unpleasant, disturbing sound while running. This sound is reduced by a footfall sound insulation. They are also best protected from cold by the thermally insulating properties of footfall sound insulation. A LVT vinyl flooris therefore pleasantly foot warm. In addition, you can compensate for minimal unevenness in the underbody with footfall sound insulation. At the same time, you also save costs by dispense with other compensatory measures.

In short, a footfall sound insulation gives you peace, warmth and stability.

Tip: If you want to lay your vinyl floor on screed or filler, don't forget to use a steam brake.  The so-called PE film is not a footfall sound insulation. Rather, it serves to protect the vinyl floor from rising moisture.

 

  1. The different types of vinyl floor impact sound insulation

With a footfall sound insulation, you can choose between different materials. Basically, natural raw materials such as wood, cork or hemp as well as plastics are available. We personally clearly tend to be plastics. They have proven themselves best in terms of price-performance ratio, are durable and water-resistant. However, the impact sound insulation should always be made of elastic material and should have a release for vinyl floors.

Impact sound insulation made of latex or PU plastic

Plastic impact sound insulation is available on the market under different names and with different properties. Here we present the two most common ones.

Latex impact sound insulation

The remarkably heavy material is soft and at the same time pressure-resistant. These properties make it an excellent material for impact sound insulation. The back is usually coated with a thin plastic film and eliminates the need for an additional steam brake.

Impact sound insulation made of polyethylene foam (PE foam)

A footfall sound insulation made of PE foam is particularly suitable for laying over underfloor heating. The air bubbles contained in the foam swallow part of the sound and thus minimize the footy sound. The thicker and denser the foam layer, the more effective the sound insulation is. In addition, impact sound insulation made of plastic is particularly resistant and suitable for practically any floor covering. In the case of vinyl floors, which already have sound-insulating properties themselves, thin impact sound insulation made of PE is usually sufficient.

 

  1. Conclusion on vinyl floor impact sound insulation

Since vinyl, in contrast to laminate, parquet or solid wooden planks, is made of a very soft material, a vinyl floor also transmits the impact sound less strongly. A thin impact sound insulation is therefore sufficient in most cases. In addition, there are special documents for vinyl floors that are perfectly adapted to the requirements of the floor. The already thin floor covering has a very low construction height due to the thin impact sound insulation.

But be careful: When purchasing your impact sound insulation, always pay attention to the release for vinyl floors, as these must have a certain compressive strength. Observe manufacturer information on the subject of footfall sound insulation and, if in doubt, ask a specialist.
