10 Best Underlayment For Hardwood Floors 2025 in the United States

The STEICO Wood Fiber Flooring Underlayment offers a 6mm (1/4 inch) thickness, which is a good middle ground for sound reduction and cushioning under hardwood and similar flooring types like laminate and vinyl. Its main strength lies in natural soundproofing, thanks to the wood fiber material that has passed rigorous acoustic testing, making it a solid choice if noise reduction is important in your home. The underlayment is breathable and features “vapor open” technology, helping to prevent moisture buildup that can damage hardwood floors, although it is not a full plastic moisture barrier, so it may not be ideal in very damp areas without additional protection.

Made from pure wood fiber without synthetic additives, it is environmentally friendly with low emissions, which is a plus for indoor air quality. Its high compression strength means it supports the flooring well without causing squeaks or a springy feel. Installation is relatively straightforward, and the product can be layered for leveling uneven floors. However, at 6mm thick, it may be slightly heavier and more rigid compared to foam or cork alternatives, which could influence ease of handling and fitting around corners or edges.

This underlayment is best suited for homeowners looking for a natural, eco-friendly material that improves sound insulation and floor comfort, especially in living spaces, rather than wet basements or high humidity zones.

The QuietWalk LV underlayment is a solid choice for anyone looking to install luxury vinyl, laminate, or wood floors. One of its standout features is its superior sound reduction capability. The recycled fibers effectively absorb sound, making floating floors feel more solid underfoot, which is great for reducing noise between rooms. Additionally, the moisture protection provided by the DriWick technology is a significant advantage, especially for those installing over concrete subfloors. It allows for moisture vapor to escape, while the attached vapor barrier protects the flooring above from potential damage.

This underlayment is also quite versatile; it works with various installation methods, whether you're floating, gluing, or nailing your floors. Its compatibility with in-floor radiant heat systems is a bonus, enabling even heat distribution, although you may want to use it alongside QuietWarmth products for optimal performance.

The thickness at 0.06 inches might not provide as much cushioning as thicker underlayments, which could be a consideration for those who prioritize comfort underfoot. While it's made from recycled materials, which is great for environmental concerns, some users might prefer a more traditional felt option for specific applications. In terms of installation, it’s relatively easy to work with, covering 360 square feet per roll, making it efficient for larger areas. However, being a bit heavier at 30 pounds may make handling a bit cumbersome for some users.

The WarmStep Model WS3012-120 is a 36 sq. ft. in-floor heated mat designed for both engineered and solid hardwood floors. One of its significant strengths is its ease of installation, which doesn't require cement or mortar and can be applied using glue, nails, fasteners, or as a floating floor. This feature is particularly beneficial for those who prefer a straightforward installation process.

Additionally, it offers the health benefits of radiant heat by eliminating drafts and airborne allergens, making it a good choice for allergy sufferers. The energy efficiency is another notable advantage, claiming up to 40% savings over conventional heating systems, which can be cost-effective in the long run. This product is designed to last for the lifetime of the floor when correctly installed and operated, providing long-term value.

The product dimensions and area coverage are practical but limited to smaller spaces, so it may not be suitable for larger rooms without purchasing multiple units. While the product does offer good moisture barrier and sound reduction properties, these features are not explicitly highlighted, which could leave some users questioning its full capabilities in these areas. This heated mat is a practical solution for those looking for easy installation and energy-efficient floor heating.
