Why Use an Underlay for your Parquet Floor?

As with any type of flooring like carpet, vinyl or tile, the installation of an underlay is important before placing a parquet. Although often neglected, the underlayment is considered by many professionals and experienced DIYers as an element which is just as important as the floor itself. Here’s why!

The Advantages of Installing an Underlay for you Parquet

The underlay for parquet is essential in the sense that it will protect your floor, and therefore your whole house, from moisture. As such, note that the vapor barrier is mandatory for the floating installation of a parquet or a laminate flooring. In addition to the protection against moisture, the underlayment provides sound, acoustic and thermal insulations. An underlay with soundproofing properties will prevent the spread of noise from one room to another, especially when both are on two different floors. It is particularly useful when the area to be covered is directly above a bedroom, for example.

The underlayment also makes it possible to improve the acoustic insulation of a room and to attenuate the noise of the steps. It relieves your ears by dampening the impact of the steps on the floor. It also helps to relieve your joints and your spine. The other advantage of the underlayment before installing a parquet floor is the thermal insulation. It helps to reduce energy needs and allows better control of its consumption. This thermal insulation is appreciable in winter and summer because it allows to minimize the differences in temperatures. Thus, you will benefit from a better comfort at home.

Choose the Right Type of Underlay for your Parquet Floor

In order to insulate your floor and protect it from moisture, it is better to use two underlays:

  • A first insulation to protect from moisture (a vapor barrier);
  • A second insulation to provide thermal and sound insulation.

While protection against moisture seems essential and obvious, it is not always the case for the second underlayment. However, it should be noted that a floating parquet floor transmits more noise than a glued floor, mainly because of the presence of the air below which it is placed. Anyway, you are advised to use a high tog underlay for laminate or parquet.

Whether it is a laminate or a floating parquet, it remains important to choose an underlay with acoustic, sound and thermal insulation qualities depending on the room in which it will be laid. Make sure that the irregularities are not greater than 2 millimeters. Then, use an insulating, a cork or an universal underlay according to your preferences and your needs.

To ensure the longevity of your floor and to provide an optimum comfort to the people who live in your house: do not underestimate the importance of the underlayment!
