How it Works
Underlayment is a barrier or pad that you put down under the laminate . Before the laminate is ever installed, the installer will lay out the padding. Then the laminate flooring is installed on top of this surface. It typically comes in rolls and can be taped together to keep it in place.
The purpose of this material is to help support the laminate flooring. As you may know, laminate flooring locks together and simply lays down the floor. You do not have to attach it to the sub-floor or the wall in order to install it. Since the laminate is free floating, you have to make sure that it is supported. When you walk on the flooring, it needs a little bit of give underneath to make sure that the locking mechanism does not crack or break over time.
Another purpose of this material is that it can act as a sound barrier. For example, the sound proof foil can help absorb some of the sound that comes from walking on the flooring. If you are having laminate installed in an apartment complex, it is essential to have this type of sound proof blue foil so that you can prevent sound from transferring between apartment units. You can also get a standard silver foil pad if sound protection is not as big of an issue for you.
If you are installing laminate on a concrete sub-floor or in an area that is below grade, you will also need to install a moisture barrier. This is a barrier that goes in before the padding is installed. It helps keep any moisture from coming up through the floor and getting into the pad or the laminate core. Laminate does not work well in moist conditions and you need to take every precaution to eliminate the possibility of allowing moisture into the planks. Once you have the right moisture barrier and the right pad, you can move forward with the laminate installation.
