In laminate flooring installations, the underlayment is a thin, flexible sheet of resilient material that is installed on top of a subfloor to act as a base for the laminate planks or tiles. The underlayment is important because it can affect how your laminate flooring feels and how it wears over time. The type of underlayment chosen should be based on the environment, the type of floor chosen, and your own personal needs for space. It is essential to follow all vendor-provided instructions about underlayment when installing laminate flooring, as improper installation or the use of the wrong underlayment can void the manufacturers warranty.

The following are some of the underlayment products to choose from when choosing an underlayment for laminate flooring:

• Standard foam underlayment: This consists of a thin layer of foam material that acts as a cushion between the subfloor and the laminate flooring. This is the most common form of laminate underlayment, and it is often used in cases when installing laminate flooring over a plywood or OSB subfloor. However, this should not be used in high-moisture areas, as it does not provide any vapor barrier characteristics.

• Cork underlayment: Cork is a natural material that is eco-friendly and provides excellent sound absorption and thermal insulation. It is thicker than foam and is a good choice for those who want a more luxurious feel underfoot.

• Felt underlayment: Felt underlayment is made from recycled fibers and is denser than foam. It provides good sound absorption and is a good choice for those who want an eco-friendly option.

• Rubber underlayment: Rubber underlayment is a good choice for those who want a moisture barrier. It is also a good choice for those who want a more durable underlayment.

It is important to note that not all laminate underlayments are created equal, and different manufacturers come up with a number of great features, which you may or may not need. The underlayment should be correctly installed with a quality underlayment beneath it to provide adequate support for laminate flooring by absorbing sound, protecting it from moisture, and offering the best thermal insulation.
