What is Underlayment?

Underlayment is the cushion that goes between the subfloor (the surface you are installing the floor on top of) and the flooring itself. It is typically made of resilient material, and it can come on its own,

Underlayment is the cushion that goes between the subfloor

attached to the flooring, or with its own moisture or vapor barrier. The different types of underlayment are foam, cork, or a combination of foam and a moisture barrier.

Do I Need Underlayment for Laminate Flooring?

Yes, laminate flooring always requires underlayment because it is a floating floor. This means the pieces lock together, but they are not glued or nailed down to the subfloor. Underlayment supports the interlocked boards of the flooring and has added benefits like noise reduction and insulation. Some flooring comes with the underlayment pre-attached.

More about, you can read in my post: Do wooden flooring need underlay?

How Thick Should Laminate Underlayment Be?

Typically, laminate underlayment is 2 to 3 millimeters (5/64 inches to 1/8 inches thick) thick. If you

are using a floor heating system, a thinner underlayment is best; otherwise, 3 mm provides effective cushioning and support. The thicker the underlayment, usually the better the noise reduction, insulation, and resilience.

What is a Vapor Barrier?

A vapor barrier also called a moisture barrier, is just what it sounds like: a barrier that

protects your flooring from water particles and the damage they can cause. This barrier protects your flooring from any moisture that could seep up from the subfloor. Using a vapor barrier is typically a

good idea, and it is necessary if your subfloor is cement or below ground level. Even if your underlayment comes pre-attached to your flooring, you will need to install a vapor barrier below the

underlayment. Some underlayments already have vapor barrier qualities.

How Do I Pick the Right Underlayment for Laminate Flooring?

The underlayment you use depends on the subfloor you are working with. You should also consider your space, what it will be used for, and your laminate floor type when choosing an underlayment. The main types of underlayment are standard foam, combination foam, and cork underlayment. Most subfloors are plywood, OSB (oriented strand board), or concrete.

For plywood and OSB flooring, standard foam underlayment works just fine. This type of underlayment is the most common and usually the cheapest. You can use combination foam underlayment with a moisture barrier for plywood and OSB, as well, but it is also necessary for the concrete subfloor.

If the environment will hold more moisture than usual, like in a basement or a bathroom, you should use combination underlayment or be sure to add a layer of the vapor barrier to the assembly.

Anytime noise reduction is a primary concern or you need to level the subfloor, cork underlayment will do the best job. This option is naturally antimicrobial, but it is also the most expensive option for underlayment.

How Do I Install Underlayment for Laminate Flooring?

How Do I Install Underlayment for Laminate Flooring?

Before You Begin:

Make sure the subfloor is completely clean and level. If you are installing a separate vapor barrier, do this first.

Step 1: Unroll and Lay Out the Underlayment

Unroll the first strip of underlayment and lay it along the longest wall. The underlayment should run the same way as the flooring. Make sure the adhesive strips on the edges are facing up when you do this. At the edges of the underlayment, allow the plastic overhang to run up the wall. This overhang will be covered by the baseboard.

Step 2: Connect the Pieces

Lay the next strip down next to the previous one. The edge of the underlayments should be touching

with only the plastic edge overlapping the previous sheet. Remove the adhesive strip from the edge of the first sheet and attach the plastic overhang tightly to the adhesive.

Step 3: Make it Fit

Go along the edges and cut out the shape of vents or other obstructions so that the underlayment can lie flat without covering anything that needs access. Make sure the corners fit securely.

What Do the Different Underlayment Ratings Mean?

There are four different official tests for sound evaluation in flooring. These are STC, FSTC, IIC, and

FIIC. These tests evaluate the sound transmission through all the flooring and ceiling layers (called the assembly) from one level of living space to another.

STC stands for “Sound Transmission Class” and FSTC stands for “Field Sound Transmission Class”

They test airborne sound transmissions like voices or

music. The only difference between STC and FSTC is that the FSTC is

conducted in an actual building rather than a sound test lab, so it

is a “field test.”

The IIC and FIIC stand for “Impact Isolation Class” and “Field Impact Isolation Class.”

They have the same difference in that one is a field test, but these tests evaluate the transmission of impact noises like footsteps or something being dropping.

What rating is permitted?

The International Building Code recommends a rating of 50 or more for the STC and IIC tests but

permits a rating of 45 or more for the field tests. Be careful when looking at underlayment ratings for various products. A rating of 70 means something is virtually soundproof, and this rating is only

Since the rating depends on the entire assembly (ceiling and/or subfloor included), this rating is going to change depending on where it is installed.

Do I need underlayment for laminate flooring on plywood?

Yes. You always need underlayment unless the laminate flooring comes with underlayment pre-attached. When installing underlayment over plywood, it may be best to skip the vapor barrier so the wood can breathe and moisture doesn’t get trapped under the floor. Consider if the room is high moisture (like a basement or a bathroom). If so, use a vapor barrier. If not, leave it out.

Can I use carpet padding as my underlayment?

No. Carpet padding is too flexible for underlayment purposes, and it can loosen the joints between the boards. The foam or cork used for underlayment provides impact absorption without allowing too much movement.

What is the difference between plywood and OSB subfloor?

Plywood is made of multiple thin sheets of wood glued together to make a strong board. OSB (oriented strand board) is made of recycled wood chips glued and pressed together. OSB is typically cheaper, more flexible, and more resistant to water. Plywood is generally tougher, more supportive, and more resistant to swelling. Both are comparable materials to use for the subfloor, but plywood is a bit stronger. This makes plywood the better choice for heavier flooring like ceramic or stone tile.

How should I care for my flooring if I have a flood or a heavy spill?

Anything that goes beyond your typical glass of spilled milk should be seriously treated to maintain the lifespan and quality of your flooring. Act quickly and clean up the water as fast as you can. Time is of the essence in a situation like this. Remove the laminate flooring in the area where the flood occurred, and allow the subfloor to dry out. Replace any flooring or subflooring that is damaged. Generally, plywood is more resistant to swelling from water than OSB, so consider this when deciding what to replace.
