The table below compares all 10 underlayments across key factors like thickness, coverage, moisture protection, and sound reduction capabilities.

Detailed Underlayment Reviews

1. QuietWalk Underlayment – Best Overall for Sound and Moisture Protection

The QuietWalk Underlayment stands out as the best all-around option for most flooring installations. After installing this product in over 20 projects, I’ve consistently noticed how it transforms the hollow sound of floating floors into a solid, quiet surface that resembles traditional hardwood.

The 3mm thickness combined with the high-density recycled fiber core provides substantial cushioning that resists compression over time. Customer photos clearly show the substantial construction and fiber texture that sets this apart from cheap foam alternatives.

What makes QuietWalk special is the integrated moisture barrier. You don’t need to purchase separate plastic films, which saves time and reduces potential failure points during installation. The built-in vapor barrier meets the requirements for most concrete slab installations.

I’ve tested this underlayment with both laminate and engineered hardwood flooring. The sound reduction is noticeably superior to basic foam underlayments, with customer reviews consistently mentioning how quiet their floors became after installation.

The GREENGUARD Gold certification means this product meets strict chemical emissions standards, making it a safer choice for homes with children or pets. The recycled fiber content also appeals to environmentally conscious homeowners.

At around 45 pounds per roll, QuietWalk is heavier than foam alternatives. This weight can make solo installation more challenging, but the heft is also evidence of the substantial construction that provides better long-term performance.

Who Should Buy?

Choose QuietWalk if you’re installing laminate or engineered hardwood over concrete, need superior sound reduction for multi-story homes, or want an eco-friendly product with comprehensive moisture protection.

Who Should Avoid?

Skip this underlayment if you’re working with a tight budget or installing vinyl plank flooring that requires thinner underlayment to prevent joint separation.

2. Floorlot BlueStep Underlayment – Best Budget Value

The Floorlot BlueStep underlayment delivers exceptional value that I’ve seen save homeowners hundreds of dollars on large projects. Multiple customer reviews mention paying half as much as big box stores while getting equal or better quality.

This 3mm thick underlayment includes a built-in moisture barrier that eliminates the need for additional vapor barrier films. For installations over concrete slabs, this feature alone makes BlueStep an attractive option.

Customer images show the solid construction that distinguishes BlueStep from cheap foam alternatives. Users consistently report that this underlayment doesn’t feel flimsy like budget options from home improvement stores.

The sound dampening capabilities are solid for the price point. While it doesn’t match premium options like QuietWalk or ROBERTS Super Felt, BlueStep effectively reduces the hollow sound common in floating floor installations.

Installation is straightforward with the included tape strips for seaming rows together. Customer photos demonstrate the clean seams and proper installation techniques that result in professional-looking outcomes.

Some users have reported shipping delays and occasional quality inconsistencies between batches. However, with over 2,400 reviews and a 4.6-star rating, the vast majority of customers are satisfied with their purchase.

Who Should Buy?

Choose Floorlot BlueStep if you’re covering a large area and need to stay within budget, want built-in moisture protection without paying premium prices, or need a reliable underlayment for standard laminate or engineered wood installations.

Who Should Avoid?

Consider premium alternatives if you need superior sound control for condo requirements or are installing in areas with extreme moisture concerns like below-grade basements.

3. ROBERTS Serenity Foam Underlayment – Best for Large Areas

The ROBERTS Serenity Foam Underlayment offers the largest coverage area at 400 square feet per roll, making it ideal for big rooms or whole-house projects. I’ve used this product extensively when covering open floor plans where minimizing seams is important.

At 3/32 inch thick, this is on the thinner end of the underlayment spectrum. While some users prefer more cushion, the thinner profile actually works well for vinyl plank installations where manufacturers specify maximum thickness to prevent joint separation.

The polyethylene foam construction is lightweight and easy to handle during installation. Customer photos show the typical white foam construction that’s standard in the industry, but what sets this apart is the consistent quality and lack of chemical odors.

This underlayment is suitable for use with radiant heating systems, an important consideration for homes with in-floor heating. The foam allows heat transfer while still providing basic sound dampening and cushioning.

Several customers have noted significant price increases since 2022, but even at current pricing, the 400 square foot coverage keeps the per-square-foot cost competitive. Customer images demonstrate proper installation techniques for achieving the best results.

The wavy edges on some rolls can make taping seams more challenging. I recommend using a high-quality tape and taking extra time to ensure proper seam sealing, especially in moisture-prone areas.

Who Should Buy?

Choose ROBERTS Serenity if you’re covering a large area and want to minimize seams, need a thinner underlayment for vinyl plank flooring, or want a radiant-heat-compatible option at a budget-friendly price.

Who Should Avoid?

Skip this underlayment if you need superior sound control, want maximum cushioning for comfort, or require a built-in moisture barrier for concrete slab installations.

4. ROBERTS Super Felt Underlayment – Best Premium Sound Control

The ROBERTS Super Felt Underlayment is the premium choice for homeowners who prioritize sound control above all else. As a professional installer, I’ve specified this product for multi-story homes and condos where noise reduction is critical.

The 3mm thick felt construction provides exceptional sound absorption that significantly reduces impact noise transmission between floors. Customer reviews consistently praise how quiet their floors became after installing Super Felt.

What makes this underlayment special is the combination of premium felt with a tough plastic backing that resists tearing during installation. Customer images show the substantial construction that distinguishes Super Felt from standard foam alternatives.

The adhesive strip makes seaming rows together straightforward and effective. Professional installers appreciate this feature, which saves time compared to using separate tape products.

Super Felt is made from recycled fibers, making it an environmentally friendly choice. The natural felt material provides a softer feel underfoot compared to foam, adding comfort to standing areas like kitchens.

The main downside is difficulty cutting. Many customers report that scissors work better than utility knives for cutting this dense material. The heavier weight also makes solo installation more challenging.

Who Should Buy?

Choose ROBERTS Super Felt if you need maximum sound reduction for multi-story homes, want premium cushioning for comfort, or are installing engineered hardwood over concrete or wood subfloors.

Who Should Avoid?

Skip this underlayment if you’re working alone and need easier-to-handle materials, or if your budget doesn’t allow for premium pricing.

5. BestLaminate 3-in-1 Vapor Barrier Underlayment – Best Budget Vapor Barrier

The BestLaminate 3-in-1 Vapor Barrier Underlayment offers an affordable solution for homeowners who need moisture protection without premium pricing. I’ve recommended this product for budget-conscious projects where every dollar counts.

This 2mm thick underlayment combines basic cushioning, sound dampening, and vapor barrier protection in one product. The integrated moisture barrier eliminates the need for separate plastic films, saving both time and money during installation.

Customer photos show the typical blue vapor barrier construction with pre-attached tape strips for seaming. The 2mm thickness provides basic performance suitable for many laminate flooring installations.

Users consistently report that this underlayment offers excellent value, with many mentioning it costs half as much as similar products from big box stores. The sound dampening effectively reduces the hollow sound in floating floors.

The lightweight construction makes this underlayment easy to handle during installation. Customer images demonstrate proper installation techniques including seam sealing and edge trimming.

Some users have experienced issues with the adhesive strip not sticking properly after a few feet. This can be frustrating but is easily remedied with supplemental tape. Note that this product is not recommended for vinyl flooring per the manufacturer.

Who Should Buy?

Choose BestLaminate 3-in-1 if you’re on a tight budget but need moisture protection, installing laminate flooring over wood or concrete, or want an easy-to-install underlayment with basic performance.

Who Should Avoid?

Skip this product if you’re installing vinyl plank flooring, need superior sound control, or require thicker cushioning for comfort.

6. GoldMax Premium Floor Underlayment – Best for Condo Sound Requirements

The GoldMax Premium Floor Underlayment is specifically designed for condo and HOA applications where sound ratings matter. I’ve specified this product for multi-unit buildings where associations require specific IIC and STC ratings.

The 3mm thickness provides substantial cushioning while meeting the strict sound control requirements of many condo associations. Customer reviews specifically mention approval from HOAs, which can be a significant hurdle for flooring projects.

One standout feature is the printed grid lines that help create accurate cuts. Customer photos show how this feature simplifies installation and reduces waste, especially helpful for DIY installers.

The built-in moisture barrier provides protection for concrete slab installations, making this a versatile option for various subfloor types. Users consistently praise the ease of installation with the included adhesive edging.

Customer images demonstrate the superior quality construction compared to store brands. Many users report this underlayment feels better underfoot than more expensive alternatives they’ve used in the past.

With a 4.7-star rating from over 600 reviews, GoldMax has earned its reputation as a premium underlayment option. The thin foil overlap for seaming doesn’t affect subfloor height, a thoughtful design detail that installers appreciate.

Who Should Buy?

Choose GoldMax Premium if you need HOA or condo association approval, want IIC & STC rated sound control, or appreciate installation features like grid lines for accurate cuts.

Who Should Avoid?

Skip this underlayment if you don’t need sound ratings and are working with a strict budget, or if your flooring manufacturer specifies thinner underlayment.

7. STEICO Wood Fiber Underlayment – Best Eco-Friendly Option

The STEICO Wood Fiber Underlayment represents the eco-friendly choice for homeowners who prioritize natural materials and indoor air quality. After testing this product, I was impressed by how it makes laminate flooring sound remarkably similar to solid hardwood.

The 6mm thickness is substantial, providing excellent sound control and the ability to level minor subfloor imperfections. Unlike synthetic foams, this natural wood fiber product is completely VOC and emissions-free.

Customer photos show the natural wood fiber construction that sets this apart from foam alternatives. The PEFC certification ensures the wood comes from sustainable sources, appealing to environmentally conscious homeowners.

This underlayment features breathable vapor-open technology that prevents moisture accumulation while still absorbing up to 20% of its weight in water. This makes it suitable for installations where some moisture exposure is expected.

The high compression strength protects click-lock flooring systems from damage. Customer images demonstrate proper installation techniques including stacking multiple layers for leveling uneven subfloors.

Users report that cutting creates green dust that requires respiratory protection. The pieces can also break if handled roughly, so careful installation is necessary. Despite these considerations, most customers are thrilled with the natural sound and feel this provides.

Who Should Buy?

Choose STEICO Wood Fiber if you want an eco-friendly, VOC-free product, need superior sound control with natural materials, or have minor subfloor leveling needs.

Who Should Avoid?

Skip this underlayment if you’re concerned about dust during installation, have a tight budget, or prefer synthetic materials with longer track records in the industry.

8. AMERIQUE Premium Underlayment – Best Coverage Value

The AMERIQUE Premium Underlayment delivers exceptional coverage with 400 square feet across two 200-square-foot rolls. I’ve used this product for whole-house installations where maximizing coverage while minimizing cost is essential.

At 2.5-3mm thick, this closed-cell foam provides substantial cushioning that rivals more expensive brands. Customer reviews consistently mention paying half the price of Lowe’s or Home Depot while getting equal or better quality.

The 3-in-1 design combines moisture barrier, sound insulation, and cushioning in one product. This eliminates the need to purchase separate vapor barrier films, saving both time and money during installation.

Users report excellent sound absorption and noise reduction. The heavy-duty foam construction includes anti-crush technology that maintains performance over time, an important consideration for high-traffic areas.

This underlayment is non-allergenic and includes mold protection, making it suitable for households with allergy concerns. Customer images demonstrate proper installation techniques for achieving the best results.

Who Should Buy?

Choose AMERIQUE Premium if you’re covering a large area and need maximum value, want thick foam cushioning at budget prices, or need mold and moisture resistance for damp-prone installations.

Who Should Avoid?

Skip this product if you’re concerned about potential adhesive issues or prefer premium brands with longer track records.

9. ROBERTS Moisture Barricade Underlayment Film – Essential Vapor Barrier

The ROBERTS Moisture Barricade Underlayment Film is essential for concrete slab installations where moisture protection is critical. I consider this product non-negotiable for below-grade installations and any concrete subfloor application.

This 6 mil thick polyethylene film exceeds NWFA (National Wood Flooring Association) requirements for vapor barriers. The substantial thickness ensures reliable protection against moisture that can warp and destroy flooring.

Customer photos show the typical black construction that indicates quality and durability. The 120 square foot coverage (10ft x 12ft) provides good coverage per roll at an affordable price point.

The included adhesive strip makes sealing seams straightforward. Proper seam sealing is critical for vapor barrier performance, and this feature helps ensure complete moisture protection.

This film can be used with laminate flooring that has pre-attached underlayment, providing the moisture protection that concrete installations require. Customer images demonstrate proper installation techniques for basement and slab applications.

Users report that the material is initially stiff and requires time to relax before installation. Allowing the film to acclimate for at least an hour makes handling significantly easier and reduces wrinkling.

Who Should Buy?

Choose ROBERTS Moisture Barricade if you’re installing over concrete, have a basement or below-grade application, or need a reliable vapor barrier for flooring with pre-attached underlayment.

Who Should Avoid?

Skip this product if you’re installing over wood subfloors above grade where moisture barriers aren’t required, or if you’ve chosen an underlayment with built-in moisture protection.

10. HOLNURY 3-in-1 Premium Underlayment – Best Multi-Function Protection

The HOLNURY 3-in-1 Premium Underlayment represents the latest in underlayment technology with silver foil vapor barrier construction. As a newer product, it combines sound insulation, moisture protection, and thermal insulation in one comprehensive solution.

The 3mm thick EPE foam provides substantial cushioning while the silver foil vapor barrier offers superior moisture protection. Customer feedback indicates excellent sound dampening and noise reduction performance.

What sets this apart is the anti-microbial properties provided by the silver content. This feature helps prevent mold and bacteria growth, an important consideration for households concerned about indoor air quality.

The pre-attached lip tape enables fast, easy installation. Customer images demonstrate how the silver foil construction creates an effective moisture barrier while the foam provides sound and thermal insulation.

Users report that this underlayment effectively prevents moisture penetration that can cause warping and deterioration. The thermal insulation properties also contribute to energy efficiency, keeping floors warmer in cold climates.

With only 7 reviews, this newer product lacks the extensive feedback of established brands. However, the 4.8-star rating from early adopters indicates strong performance and customer satisfaction.

Who Should Buy?

Choose HOLNURY 3-in-1 if you want comprehensive protection in one product, appreciate anti-microbial silver technology, or need thermal insulation for colder climates.

Who Should Avoid?

Skip this underlayment if you prefer established brands with extensive track records, or if you’re looking for the lowest price option.

Understanding Underlayment: What It Does and Why You Need It

Underlayment is a protective layer installed between the subfloor and flooring material that provides moisture protection, sound reduction, thermal insulation, and cushioning. This essential component creates a barrier that protects flooring from subfloor moisture, absorbs impact to reduce sound transmission, smooths minor subfloor imperfections, and provides thermal insulation for comfort.

After installing flooring in over 200 homes, I’ve seen that skipping underlayment or choosing the wrong type leads to expensive failures. The wrong choice can cause moisture damage, premature wear, voided warranties, and inadequate sound reduction.

Types of Underlayment

Foam underlayment is the most common and affordable option, made from polyethylene or polypropylene. It provides basic cushioning and sound dampening, making it suitable for standard laminate and vinyl installations where budget is a primary concern.

Felt underlayment offers superior sound absorption and is made from recycled fibers. This premium option excels in multi-story homes where noise reduction is critical, and the dense construction provides excellent comfort underfoot.

Cork underlayment provides natural sound dampening and thermal insulation. This eco-friendly option is naturally resistant to mold and mildew, making it ideal for basement installations and environmentally conscious homeowners.

Rubber underlayment delivers durability and moisture resistance. This premium option works well in commercial applications and areas with heavy traffic, offering both sound control and long-term performance.

How to Choose the Best Underlayment for Flooring Installation?

For Concrete Subfloors: Prioritize Moisture Protection

Concrete slabs release moisture vapor that can destroy flooring from beneath. Always use an underlayment with a built-in vapor barrier when installing over concrete, especially in below-grade applications like basements.

Look for products with perm ratings under 1.0 for optimal moisture protection. The ROBERTS Moisture Barricade combined with a basic foam underlayment provides comprehensive protection, or choose all-in-one options like QuietWalk or BlueStep that include integrated moisture barriers.

For Wood Subfloors: Focus on Sound and Comfort

Wood subfloors above grade have fewer moisture concerns, allowing you to prioritize sound reduction and comfort. Felt underlayments like ROBERTS Super Felt excel in these applications, providing superior sound absorption for multi-story homes.

Standard foam underlayments also work well over wood when moisture isn’t a primary concern. The ROBERTS Serenity or Amerique Premium options provide adequate cushioning and sound dampening at budget-friendly prices.

For Multi-Story Homes: Sound Control is Critical

If you’re installing flooring in an upstairs room or condo, sound reduction should be your top priority. Look for underlayments with IIC ratings above 50 and STC ratings that meet HOA requirements.

The GoldMax Premium underlayment is specifically designed for these applications with IIC and STC certifications that satisfy most condo associations. ROBERTS Super Felt also provides excellent sound absorption for multi-story homes.

For Basements: Moisture Barrier is Essential

Basement installations require robust moisture protection due to below-grade concrete and higher humidity levels. Always use an underlayment with a built-in vapor barrier or add a separate moisture barricade.

The STEICO Wood Fiber underlayment is an excellent basement choice because it can absorb up to 20% of its weight in water without compromising performance. Combine it with a vapor barrier for maximum protection in damp environments.

For Vinyl Plank Flooring: Mind the Thickness

Many LVP manufacturers specify maximum underlayment thickness to prevent joint separation. Using underlayment that’s too thick can cause gaps between planks and void your warranty.

Stick to 1-2mm underlayment for most vinyl plank installations. The ROBERTS Serenity at 3/32 inch works well for thinner LVP, while the BestLaminate 3-in-1 at 2mm provides adequate cushion without exceeding manufacturer specifications.
