Why Is Underlayment For Laminate Flooring Necessary?

We’ve heard many people ask, “Do I need an underlayment for laminate flooring?”. The answer is – you may not need to use any layer under the laminate floors in your home. But installing one offers you several advantages. A few of them are discussed below:

Moisture Protection

Moisture is a killer that can migrate upward from any concrete slab. This causes loosening of gums, floor twisting, and growth of mold and mildew. Fixing a moisture-proof underlayment or vapor barrier on concrete can eliminate the problem.

Thermal Insulation

Concrete floors make your feet cold regardless of the thickness of the laminates. An underlayment layer offers thermal properties that keep your floor warm. Felt-type underlay offers the best thermal insulation.

Sound Absorption

Laminate flooring is not so thick as solid hardwood. Also, it is made of low-density fiberwood. Hence, there are high chances the sound passes from floor to floor when applying laminate flooring in the house. An underlayment increases the sound absorption capability of the laminate.

Softens Footfall

While installing thin laminate flooring on a hard surface like concrete, you need an extra underlayment to make it easy and soft to walk on. Laminate flooring with denser underlayment can make you feel good while walking as you feel a solid basement under your feet.

Corrects Subfloor Imperfections

Concrete subfloors are not perfectly flat and featureless. They are often dotted with gaps, nail holes, pit, and splinters. If you were using solid hardwood, that could run directly over concrete, ignoring the imperfections. Also, the ceramic tiles can bridge small gaps and pits to work nicely. But laminates can’t handle all imperfections because of their less-denser quality. So, you need to apply underlayment on the concrete to correct the imperfections.

Ensures Stability

Laminate flooring without underlayment is more prone to damage and expansion, making them unstable. Installing an underlayment provides stability that joints the floor with concrete.

What to Consider Before Buying underlayment for laminate flooring?

The right underlayment can enhance the feel of your laminated floor like never before. And the last thing we want is you ending up wasting your money on the wrong one. Check these factors given below to find the perfect one that meets your needs:

Room Location

If you’re living on the upper floor of an apartment, then consider buying an underlayment that absorbs noise. Because without the proper underlay with a high sound reduction rating, noise can easily transfer.

Subfloor Type

The subfloor material plays the most significant role in determining the type of underlayment you’ll need. If you have a concrete subfloor installed or plan to use, then go for the underlay with a vapor barrier. Because concrete is porous and retains moisture. This can cause the adhesive to loosen, flooring to distort, and mold to develop. So, get the underlay that comes with moisture resistance.

If you’ve got a plywood subfloor, then install the underlayment that contains semi-permeable material. Doing so will help with air circulation and prevent mold buildup.

For the wood subfloor, moisture resistance is not mandatory. Consider other factors like noise reduction and all.

Thermal Conductivity

The concrete subfloor makes the laminated floor cold. If you hate that or live in a place where it’s freezing, get an underlay with a higher R-value. More R-value indicates less heat will be able to pass through it. That means it will hold the heat and make your feet feel warmer.

Usually, foam underlay has less R-value than fiber or felt underlayment. So if you want a nice and warm floor, go with fiber or felt underpad. Their R-value is about 0.5-0.6.

Noise Reduction

The only limitation of the laminated floor is it makes a hollow-like sound. Lucky for you, it can be efficiently reduced by the underpad that comes with a good STC and IIC rating.

Now, the STC or Standard Transmission Class indicates the protection against airborne noises. Again, IIC or Impact Isolation Class determines the impacts like drops and footstep sound reduction capability.

So, for the rooms where a peaceful environment is needed, like the bedroom or study, get the underlay with a higher STC and IIC rating.

Anti-microbial Properties

Depending on the environment, you might need the underlayment that comes with anti-microbial properties. Some under-pad like cork come with natural anti-microbial benefits. Again, some underlays are designed by the manufacturers to be anti-microbial.

So, to prevent your floor from bacteria and fungi buildup, go for the anti-microbial underlayment.

Types Of Underlayment For Laminate Floors

There are mainly four types of underlayment options you have to fit on concrete for laminate flooring. Apart from serving basic requirements, each type offers special benefits. Let’s find them out in detail.


Felt-type underlayment is great for preventing moisture from migrating upward to the laminates. The products are very popular to be used with laminate, hardwood, and engineered flooring. The best thermal insulation under laminate flooring products also keep the floor warm in winter and cool in summer.

Because of the heaviness and high-density materials, felt products are excellent for sound absorption. The materials used are mostly recycled fibers. As a result, the type of product is the most environment-friendly.


This is the most commonly used type of underlayment because of its easy installation process. As a homeowner, you can install it by yourself without needing any help from others. The products are one of the cheapest options. Regardless of the low price, the type ensures moisture barrier and sound absorption.


It is another type of underlayment made of the bark of cork trees. The type is the best for its capability to absorb sound. If you laminate on a floor with downstairs neighbors, it’s really important to ensure no sound is passed through. The cork materials are proved to be extremely efficient in case of sound absorption.

Cork is also eco-friendly because of its green raw materials. This type of product is very durable that eliminates the hassle to change after a few years. The anti-microbial nature of raw materials helps it preventing the growth of bacteria or mold. This results in a healthy home environment.


This is the least popular type of underlayment. It also offers high-quality performance made from rubber materials. The products provide a strong layer to reduce the passage of transmitted noise.


Attaching an underlayment ensures sound reduction, moisture-free healthy, and comfortable living if you install laminate flooring. Foam is the cheapest option, while felt is the most premium option. However, all types of underlayment can effectively do their basic duties.
