The QuietWalk LV Luxury Vinyl, Laminate, or Wood Underlayment is a versatile choice for anyone looking to install new flooring. Its compatibility with various flooring types, including luxury vinyl, laminate, and wood, makes it highly adaptable. This underlayment can be used with floating, glue-down, or nail-down installation methods, which offers great flexibility depending on your specific project needs. One of the standout features is sound reduction; the recycled fibers effectively absorb sound, making your floors quieter to walk on and preventing noise from spreading between rooms. This is particularly useful in multi-story homes or buildings. The product also boasts compression resistance, meaning it can handle heavy foot traffic without flattening or losing its supportive qualities, thus protecting your floor seams in the long term.

Moisture protection is another critical strength, with its DriWick technology allowing concrete subfloors to breathe and the attached vapor barrier safeguarding the floors above from moisture damage. It's also safe for indoor air quality, containing no VOCs or harmful emissions. Additionally, it’s compatible with in-floor radiant heat systems, ensuring even heat distribution while protecting your flooring material. However, one potential drawback could be its relatively thin profile (0.06 inches), which might not provide as much cushioning compared to thicker underlayment options. For those seeking environmentally friendly options, it’s made from recycled synthetic fibers and produced in the USA, adding an eco-conscious aspect to its benefits. Covering 360 square feet per roll, it’s sufficient for larger spaces but may require multiple rolls for extensive projects. This underlayment is a solid choice for those prioritizing sound reduction, moisture protection, and versatility in installation methods.

The ROBERTS Super Felt Underlayment is designed for use with engineered wood and laminate flooring, making it a versatile option for various settings, whether below, on, or above grade subfloors.

One of its major benefits is the moisture barrier provided by the top film, which helps protect your flooring from harmful moisture vapor.

At 3 mm thickness, it offers decent cushioning and can help correct minor sub-floor imperfections, providing a smoother surface for your hardwood or laminate floors.

With a thickness of 2 mm, it provides a decent padding layer that enhances comfort underfoot and contributes to noise reduction, boasting a Sound Transmission Class (STC) rating of 67 and an Impact Insulation Class (IIC) rating of 68.

Buying Guide for the Best Underlayments For Hardwood Floors

Choosing the right underlayment for your hardwood floors is crucial for ensuring the longevity and performance of your flooring. Underlayment serves as a protective layer between the subfloor and the hardwood, providing benefits such as moisture protection, sound reduction, and added comfort. To make an informed decision, you need to understand the key specifications and how they align with your specific needs and conditions of your home.
Moisture BarrierA moisture barrier is a layer within the underlayment that prevents moisture from seeping up from the subfloor into the hardwood. This is particularly important in areas with high humidity or where the subfloor is concrete. If you live in a humid climate or are installing hardwood in a basement, look for underlayments with a strong moisture barrier. For drier areas, a basic moisture barrier may suffice.
Sound ReductionSound reduction refers to the underlayment's ability to minimize noise from footsteps and other impacts. This is especially important in multi-story homes or apartments where noise can travel between floors. Underlayments with higher sound reduction ratings are ideal for these situations. If noise is not a major concern, a standard underlayment with basic sound reduction properties will be adequate.
ThicknessThe thickness of the underlayment can affect both comfort and sound insulation. Thicker underlayments provide better cushioning and sound absorption but may raise the height of the floor, which can be an issue with door clearances and transitions to other flooring types. For most residential applications, a medium thickness is a good balance. If you need extra cushioning or soundproofing, opt for a thicker underlayment.
MaterialUnderlayments are made from various materials such as foam, cork, rubber, and felt. Each material has its own set of benefits. Foam is lightweight and easy to install, cork is eco-friendly and offers good sound insulation, rubber provides excellent moisture protection, and felt is durable and offers good cushioning. Choose the material based on your specific needs, such as environmental concerns, ease of installation, or specific performance characteristics.
Compatibility with Flooring TypeNot all underlayments are suitable for all types of hardwood flooring. Some underlayments are designed specifically for engineered hardwood, while others are better suited for solid hardwood. Make sure to check the manufacturer's recommendations for compatibility with your specific type of hardwood flooring to ensure optimal performance and warranty compliance.
Installation MethodThe installation method of the underlayment can vary, with some requiring glue, nails, or staples, while others are simply laid down. Consider your DIY skills and the complexity of the installation process. If you are installing the flooring yourself, you might prefer an underlayment that is easy to work with and does not require specialized tools or adhesives.
