10 Best Laminate Underlayments 2025 in the United States

The QuietWalk LV Underlayment is a solid choice for anyone looking to enhance their flooring experience with luxury vinyl, laminate, or wood floors. One of its standout features is the superior sound reduction offered by the recycled fibers, which can significantly minimize noise transfer between rooms, creating a quieter living environment. This makes it particularly beneficial for apartments or multi-story homes where noise can be a concern.

Another great aspect is its compression resistance. This underlayment effectively supports the seams of your flooring, ensuring that it won’t flatten over time even with consistent foot traffic. Additionally, it includes a moisture barrier that protects your floors from potential damage due to moisture vapor emissions, making it suitable for use over both concrete and wood subfloors.

Moreover, the product is environmentally friendly, made from recycled synthetic fibers without harmful VOCs, which is a plus for indoor air quality. It’s also compatible with in-floor radiant heating systems, allowing for even heat distribution while protecting your flooring from thermal shock.

The ROBERTS Black Jack Underlayment is designed for use under laminate and engineered wood flooring, making it a versatile option for many homeowners. With a thickness of 2.5 mm, it provides a good balance of cushioning and support. The large 600 sq. ft. roll is cost-effective compared to buying multiple smaller rolls, which is a plus for those covering large areas. This underlayment is particularly suitable for use over radiant heated floors, adding to its versatility.

One of its standout features is the sound insulation, with an IIC rating of 70 and an STC rating of 66, which means it effectively reduces noise transmission, making it a good choice for multi-story homes or apartments. Installation is made easier with the included plastic overlap and adhesive strip, although beginners might still find it a bit challenging without prior experience. Since it is made from synthetic materials, it may not be the best choice for those looking for eco-friendly options. Additionally, while it is effective at reducing sound, it might not completely eliminate noise for those needing extreme soundproofing.

In conclusion, the ROBERTS Black Jack Underlayment is a reliable and cost-effective option that provides good sound insulation and is easy to install, making it a suitable choice for most laminate and engineered wood flooring projects.

This STEICO Wood Fiber Flooring Underlayment offers a 6mm (1/4 inch) thickness, which is a good middle ground for cushioning and support beneath laminate, vinyl, LVT, LVP, or hardwood floors. Made from natural wood fibers without glue or harmful chemicals, it’s a breathable and eco-friendly choice that helps prevent moisture buildup through its “Vapor Open” technology. It also stands out for soundproofing, having passed strict acoustic tests to reduce noise from footsteps, making it a solid pick if quiet floors are important to you.

The high compression strength means your floor’s click-lock system stays protected, reducing squeaks and the feeling of a springy floor, which can improve the durability and comfort of your flooring. This underlayment comes in sheets covering 180 square feet total, suitable for medium-sized areas. One thing to note is that while it’s great at minor moisture absorption, it isn’t a full moisture barrier like some synthetic underlayments, so in very damp environments you might need an additional vapor barrier.

Being a natural fiber product, it tends to be heavier and thicker than foam options, which might require some extra effort during installation and can slightly reduce floor height. If you want a natural, sound-absorbing underlayment that supports a variety of floor types and improves comfort without chemical additives, this STEICO product is a strong candidate.
