"Quiet here!": The impact sound insulation

In the present more importantly than ever, with the building of houses it may be missing in no case and also with the renovation it should come always to the use. And yet it acts invisibly, shuns the spotlight and is a quiet player in the truest sense of the word: footfall sound insulation is at the seam of time and essential for long enjoyment of the selected floor covering.

The living room is a place of peace and relaxation for everyone: long working days come to an end here and cosy hours provide comfort in a feel-good ambience. Loud noises and echoing sounds caused by movement on the upper floor of the neighbours are not only perceived as a disturbance, they also damage health and well-being in the long term. With the right impact sound insulation, you can enjoy quiet hours and fully focus on your free time. 

Impact sound insulation is created with the help of special products such as insulating underlays and foils, which lie between the floor covering and the subfloor. It dampens the springing of the floor and thus the resulting noises.

Without impact sound insulation it gets loud - and expensive

Impact sound insulation is an important aspect, especially due to the current high use and popularity of laminate, parquet and design flooring, because especially here shoe heels can cause a tremendous noise during walking movements or the raving movements of children interrupt the silence.

If tenants feel disturbed by impact noise, this can be expensive for the landlord: Depending on the floor covering, the landlord is obliged to retrofit suitable insulation. By removing the old floor covering, installing impact sound insulation and laying a new floor not only a lot of time is lost, but also money. Before the subsequent installation of impact sound insulation becomes a disaster, you should consult your JOKA specialist consultant for competent and professional advice.

The right impact sound insulation must therefore be thought of at an early stage.

The ideal result of impact sound insulation is achieved in new buildings: In order to avoid later retrofitting, it is important to think about the correct insulation of the floor in advance, because different impact sound insulation is required depending on the floor covering.

Carpets naturally have good sound absorption and reduce running noise by 25 to 34 decibels. For other floor coverings, on the other hand, impact sound insulation is irreplaceable: With parquet and laminate as classic wooden floors, insulation underlays made of polystyrene, cork, wood fibre and hemp felt are best suited. Design floors, PVC and CV floors prefer PE foam or film, which can also reduce noise by up to 30%. On the one hand, the neighbours in the upper and lower floors can no longer hear it, and on the other hand you can hear it too: because the right impact sound insulation also reduces walking noise.

And what is walking noise?

Footfall sound and walking noise are often confused, but the two terms stand for different phenomena: footfall sound is the sound perceived in other rooms through movement, while walking sound is the sound in one's own rooms.

Quality is decisive

The planning of the right impact sound insulation is important and should be carried out professionally, because the desired floor covering on the wrong insulation is not only annoying, but also does not bring the desired effect. The main focus should be on the quality of the correct underlay in order to achieve the best possible sound insulation. Although impact sound insulation from the low-price segment is relatively inexpensive, it often has a reduced quality and can drive up costs enormously by replacing it again. 

How expensive the installation of impact sound insulation is depends in the final defect on the number of square meters of the room, the costs per square meter of impact sound insulation and the hourly wage of the skilled craftsman.
