Why People Use Underlayment
People use underlayments on the floor because of the comfort it provides under their feet. It also helps to reduce sound and prevent moisture. Comfort may seem like an unusual thing to worry about when it comes to flooring, but it can be tough to walk on concrete and hard surfaces.
Furthermore, underlayments can make a big difference in how it feels to be on your feet all day. Reducing the sound is also a significant factor in the use of underlayments. It’s not just about drowning out the sound of footsteps, but also about all the sounds.
For example, if you are laying the floor in a child’s room or you have neighbors downstairs, then underlayments can lower the sounds that occur in this space. This means less transmission of sound from room to room and between floors and may be necessary for some apartments.
Some underlayments do not provide moisture barriers. Also, it is not required by all floor situations, but they are useful in several cases. However, when installing floors over concrete, it is essential because groundwater can rise through the concrete and cause mold or damage to the floor.
Other situations find a moisture barrier beneficial, for example, when the floor is laid in a room by the pool or in a bathroom or kitchen where moisture is common. Having that layer of moisture barrier for spills and frequent moisture means protecting your subfloor in the long run while slowing down any flood damage.

vi. Certified clean and safe for indoor air quality
You do not want to install underlayments that stink and can trigger allergies. Underlayments should not be smelly or even give off strange odors.
