Which underlay do I choose? With or without vapour barrier?

As far as load resistance is concerned, a good underlay can distinguish itself both in terms of dynamic and static load. Dynamic load refers to the ability of the subfloor to maintain its mechanical characteristics over time despite repeated walking stresses. The term static load, on the other hand, emphasises the ability of the mat to withstand load stress concentrated at a specific point in the room.

Underlays are recognised as playing an essential role in thermal insulation. They protect against the cold by allowing the temperature to remain constant.

The importance of underlays in heat conduction in the presence of heated floors should not be forgotten. The low heat resistance index of the heating coils avoids possible energy wastage.

Finally, protection against rising humidity. It is this characteristic that makes underlays a highly recommended purchase for people looking for adequate protection for laminate floors. These floors are particularly sensitive to humidity.

What is the risk? That with the passage of time, and constant infiltration, the floor will eventually expand, making it extremely difficult to restore its original condition.

It is strongly discouraged to install laminate flooring DIRECTLY on screeds (especially if freshly made) or tiles.

We recommend the purchase of 3in1 underlays, underlays with underlay + vapour barrier + isolating tape.
