How To Select Best Laminate Underlayment [+Buyers Guide]

Laminate flooring needs an underlayment, Don’t skip it. Underlayment will help prevent clicking sounds as you walk across it and make your floor feel a bit softer. It also makes the installation of the planks easier and removes even small inconsistencies on the sub-floor.

Some underlayment comes with self-adhesive tape while others require separate tape to join in a row thus improving your floor permeability. Make sure to buy and install the best-required underlayment for laminate flooring.

Here are a few factors to pay attention to when planning to purchase a laminate flooring underlayment.

1. Type of Sub-floor

The sub-floor installed or you plan to use, plays a major role in determining the need for underlayment. For a Plywood sub-floor, you don’t require a sturdy underlay like for concrete. With the plywood sub-floor, you may trade the vapor barrier requirement for the underlay with sound and thermal characteristics.

For concrete sub-floor, moisture is a big impediment. The concrete subfloor is porous and tends to hold water moisture. I would recommend the best underlayment that can help prevent any moisture from the sub-floor as well as the underlayment for the basement floor.

2. Thermal Ratings

Many underlayment have a thermal rating( R-value). The R-value helps to determine the underlayment heat conductivity ability. The lower the value, the better the heat conductivity or higher the heat will run through it. If you are in a climatic area that requires installing the floor heat system, pay more attention to the R-value of the underlayment.

3. Sound Absorption

Laminate flooring is known to have a hollow like sound. Sound Transmission Class (STC) ratings and Impact Isolation Class (IIC) ratings are very important for laminate underlayment.

The STC & IIC ratings help determine the number of decibels and types of sound the underlayment can help reduce. STC ratings show the airborne noises and IIC ratings measure the impact (drops and footsteps) and sound reduction ability.

Consider these sound ratings especially if you are laying the floor on commercial and apartment buildings.

4. Cost of Underlayment

Underlayment is sold in rolls or square footage and they differ in pricing. Buying in rolls is always cost-friendly but, depending on your project size, you may opt to buy in square foot. Another fact that determines the price is the number of features and brand. Always compare your budget against the cost of the underlayment, you can get high-quality underlayment for under $.15 per square foot depending with your location

5. Thickness of the Underlayment

Perhaps this was the main question you had in mind, underlayment thickness is mostly what many underlay customers struggle with. Its good to mention that other factors such as type, sound ratings, and density do matter just as much, but not more than the thickness of the underlay materials.

6. Other properties

Antimicrobial properties– some underlayment like cork have added advantages, such as natural antimicrobial characteristics. Depending on your flooring need and the environmental conditions of where you want to install it. These properties plays an important role and make your laminate floor more healthful.

Is Underlayment for Laminate Necessary?

You might be accustomed to floors like solid hardwood, engineered wood, and tiles that don’t require an underlayment. However, the laminate floor just like vinyl plank flooring requires an underlayment. Nonetheless, there are some scenarios where laminate may not require an underlay like laminate flooring with padding.

Laminate with Pre-attached pad

You don’t need underlayment for laminate flooring with an attached pad on the bottom. If you plan to buy laminate with pre-attached underlay, it needs no extra investment to put a separate underlayment. Adding an extra underlay will compromise the stability of your laminate flooring. In some areas like the basement, manufacturers still recommend you install additional vapor and moisture barrier.

Laying a separate barrier, however, as opposed to the pre-attached pad has some additional benefits.  Separate underlayment will help provide a very cohesive barrier under the laminate flooring.

Floor Areas

Some areas that receive little traffic or attention may not necessarily require hefty investments. In case you are looking for a quick flooring installation for spaces like mudroom or laundry room, your laminate flooring may simply be installed without an underlayment.

Types of Laminate Underlayment

The best underlay for laminate is readily available and in a variety. The main basic types of underlayment -laminate flooring include;

Standard Foam Underlayment

This is the most commonly used underlay for laminate available. It is thin with foam padding about 1/8 inches thick. It’s available in roll and offers minimal sound reduction and has no moisture barriers.

Combination Foam Underlayment

This is a combination of foam and vapor barrier underlayment to help protect your subfloor from moisture damage. It can be installed in areas with concrete and OSB/ plywood subfloor in the basement and bathrooms. However, it’s slightly more expensive than standard foam underlayments.

Vinyl-Backed Underlay

The vinyl underlay provides noise-proofing qualities, but, as a priority, the seams must be sealed for moisture-proofing.

Felt Underlayment

Felt underlayment provides good sound reduction characteristics in addition making your floor comfortable underfoot. The underlay also come with a built in vapor barrier to helps protect your hardwood or laminate flooring from moisture.

Cork underlayment

cork underlayment comes with added benefits, its natural antimicrobial characteristics. It’s the best choice where sound or noise reduction is important. While it helps level out uneven surfaces between rooms, it provides no cushioning or comfort underneath, but it may end increasing the laminate floor installation cost by 50 percent. To increase its moisture barrier it’s advisable to put a sheet of plastic under your cork underlay.

Tip: Felt and Cork underlay help to reduce the hollow sound produced while walking on a laminate floor. In addition, it also comes with a moisture barrier.

I’ve been working with floors for over 12 years. I started as a flooring contractor, primarily in materials selection. Then, I switched careers into accounting, so my wife and I began buying, renovating, and re-selling homes on the side. You’d be surprised how much value you can add to a home simply by adding new floors.

  1. What is some of the better underlayment with a high r-value. I’m going to remove carpet in a bedroom and replace it with laminate. Below the bedroom is an unfinished store room with concrete floor. Sub-floor in bedroom is plywood. Thanks-Richard
