Best for Noise Reduction: QuietWalk Underlayment
Unlike hardwood floors where a bit of flexibility is desired, tile surfaces need rigidity. The combination of tiles and grout would break up over time with a flexible underlay. Therefore, denser, more solid materials like Schluter-Ditra XL’s rubber underlay are the best choice for providing a solid foundation to keep the floor protected.
The XL’s rubber structure forms a grid pattern that keeps weight down while still providing the rigidity necessary for tiled surfaces. This will prevent the surface from deforming or cracking after extended use. Each roll provides 175 square feet of coverage and comes with a layer of vapor management to keep moisture from getting trapped underneath the tile surface.Continue to 5 of 8 below.

Best Budget: TrafficMASTER Standard Floor Underlayment
Trim expenses without cutting corners by choosing a budget floor underlayment. TrafficMASTER is one of the leading names in floor coverings and their standard underlayment costs less than .30 cents per square foot while providing adequate protection for your laminate or engineered flooring.
This is a 2-in-1 floor underlayment that provides cushion along with a moisture barrier. It’s only 2mm thick, which is less than some cushier options on the market. However, users find the quality to be suitable at this low price point. The most common complaint is that the center of the rolls is wound so tight that this part of the underlayment must be flattened prior to installation.
While this budget underlayment includes tape strips to secure the underlayment during installation, some people found the adhesive to be subpar. You may need to use additional tape for a more efficient and long-lasting bond.
