I’m laying a laminate floor in a room with no insulation below or above. There’s a basement beneath the room and a ceiling without insulation above it. I’m worried about noise. Can I put down two layers of laminate flooring underlayment to increase the sound absorption?

Underlayment is an essential part of any flooring project. Not only does it add a barrier of protection between your subfloor and the planks of laminate, but it also reduces noise. Some types of underlayment even help to keep moisture out of your room.
In rooms where noise is a concern, such as yours with a basement below and a ceiling without insulation above, it makes sense that you’d like to take extra steps to reduce sound. However, adding a double layer of laminate flooring underlayment isn’t the ideal solution.
Manufacturers of underlayment say that adding two layers of this essential product can actually do more harm than good. The underlayment can shift while you’re walking on it. Over time, this can also cause the planks of laminate flooring to shift. As they do, you’ll start to hear squeaking sounds from the flooring rubbing against each other. Over the lifetime of your flooring, this can cause further damage, reducing the quality of your laminate.
Since noise is a concern, we suggest getting a three-in-one underlayment. This is the thickest style of underlayment, so it provides the maximum level of sound absorption.
Three-in-one underlayment products also block moisture. This could prove extremely helpful to you because there is a basement below without added protection against leaks or spills.
