The purpose of the underlayment is to provide stability beneath the floating laminate flooring. The underlayment offers additional properties such as sound absorption, thermal insulation, or moisture protection depending on its quality.

Without underlayment, there may be echo, and noises are more easily transmitted to the space and the floors below. Its properties are maintained over time and do not favor the growth of fungi and bacteria, while it does not irritate the respiratory system.

The main purpose of the underlayment is to provide a smooth, flat surface, reducing the imperfections of the subfloor.

• Smoothing out minor imperfections of the substrate floor.
• Stability to the floor.
• Thermal insulation (depending on its category).
• Sound insulation (depending on its category).
• Acts as a vapor barrier.
• Makes walking easier.
