Pick the Best Underlayment For Laminate Flooring

Reading Time: 9 minutes

The underlayment for laminate flooring installations is a thin, adjustable sheet of resilience material laid on top of a subfloor to serve as a basis for the laminate planks and tiles primarily installed. 

Whereas the subfloor serves as the room’s base, the underlayment supports primary flooring material directly and improves and preserves it. 

It serves several purposes: It raises the floor somewhat, cushions the laminated planks, lowers sound transmission, & raises the R-value of the floor slightly.

Underlayment selection & installation are critical because they could alter how the laminate flooring looks & wears throughout time. 

The sort of underlayment you choose should be determined by the surrounding surroundings, the kind of floor you’ve chosen, & your space requirements. 

When implementing laminate flooring, it is critical to follow all vendor-provided underlay recommendations since poor installation, and the usage of the inappropriate underlayment could void the company’s guarantee.

Subflooring Made Of Concrete & Plywood

Concrete subfloors: The most significant worry when installed over the concrete floor is dampness. Concrete seems to be a porous substance, allowing water to soak up through it & onto your flooring. 

Coatings might loosen, flooring boards might warp, & mold and mildew could grow as a result. If you have concrete flooring, you’ll need a vapor barrier underlayment that keeps moisture from passing through to the laminate installation. 

The thin foam padding material consisting of polyethylene/polypropylene that rolls out in layers is the most common option.

When placing laminate flooring on plywood and OSB subfloors, a permeable foam-type underlay is typically employed. 

Because hardwood would be a natural substance that requires breathing, so won’t need to utilize a vapor-barrier-Kind underlay when putting laminates on even a conventional plywood floor in certain circumstances. 

Installing the vapor barrier above this might cause moisture to be trapped inside the material, resulting in mold growth and warping. 

An exception is installing lamination inside a high moisture location like a bathroom and basements, where a water-resistant underlayment is recommended.

When it comes to picking an underlay for laminate, there are many options available, & knowing what to search for will help.

Considerations For Insulation, Noise, & Antimicrobials

Its R-value measures the heat conductance of a substance. With a higher R-value, more heat can pass via the underlayment, and the greater the R, the lesser insulation that underlayment offers. 

In the wintertime, an elevated r value underlayment would make your floor seem warmer underneath.

Noise reduction: Certain types of underlayment for laminate flooring can help to reduce noise transmission. It is crucial in some workplaces where silence was required and in bedrooms wherever peace & quiet.

 Laminate flooring can be noisy, but a suitable underlay could help reduce noise transmission.

Antimicrobial qualities: Some underlayment substances include antimicrobial properties, which can improve the health of your laminated flooring installation. Some materials, like cork, are organically endowed with certain traits, whereas others have them.

Laminate Underlayment Types

Using carpet padding and another soft, dense underlayment inside to improve comfort when walking on some kind of laminate flooring is a typical mistake. However, this will simply cause the floor to flex significantly, potentially loosening joints. 

Underlayments for flooring should be fragile foam sheets that soften the surface slightly but just don’t permit perceptible motion underfoot. 

Spreading these materials over the flooring & sealing the gaps with glue strips occasionally pre-attached to the subfloor is how they are installed.

Underlayment Made Of Standard Foam:

Between the bottom & the laminate, there is a slight coating of foam that works as cushioning. It is the simplest popular type of laminate underlay, & it’s commonly utilized for placing laminate flooring on plywood / OSB. However, because it lacks vapor barrier properties, it must not be used in high-moisture locations. It was rolling down regular foam underlay over the foundation.

Underlayment Made Of A Combination Of Foams:

This form of underlayment mixes ordinary foam with the vapor barrier layer to protect your installation against moisture, as the name implies. Such underlayment is somewhat more costly than conventional foam, but it is suitable for plywood/OSB & concrete subfloor or may be utilized in various settings. That’s the kind of underlay that should be used in damp areas like bathrooms & basements.

The Underlayment Of Cork:

When noise reduction becomes necessary, this substance is employed in flooring constructions. Cork is among the most costly underlayment options, adding up to 50% to the laminate floor installation costs. Though it does not add any cushion or warmth to a hardwood floor, it could level off rough edges across rooms. It also possesses natural antibacterial properties.

STEICO Flooring Underlayment


  • Manufacturer- Steico
  • Color- Green
  • Material- Wood Fiber
  • Size- ⅛ thickness
  • Shape- Rectangular
  • Usage- Commercial/ Residential

Because of the great thickness of wood fiber natural insulating, it is outstanding in decreasing aerial sound like a conversation, music, & traffic sound and impacting sound like a footstep, moving equipment & rain noises via walls, carpets, & other surfaces.

The capacity to withstand pressure while being non-foamy ensures that flooring does not creak at the cracks. Rather than being soft & elastic, underlayment must be strong & flexible. It maintains the floors firm & strong under the feet, preventing “floating” & “springy” effects when moving. It also keeps your doors from breaking & extends the life of the hard floor.

Implement strategies that are most beneficial to you. For example, you can put it in multiple layers to increase the level (if necessary) and add soundproofing to drywall. Ideal for use in radiant heat pumps installed beneath the floor.

It could adjust to changes in the amount of moisture in the atmosphere where it’s positioned. Because of its propensity to collect extra water from the atmosphere and then release it when the weather is clear, it also acts as a naturally indoor microclimate controller within these spaces. This procedure reduces the likelihood of stale odors by preventing mold & mildew development beneath the flooring coverings.


Air could circulate thanks to “Vapor Open” innovation. Because it is a unique & porous substance, it may collect 20% from its original weight and prevent a minor leak.

Final Thoughts:

The purpose of the underlay for the panels is to ensure that the surface is equal and solid. Unfortunately, several factors influence the selection of a specific material. As a result, it’s challenging to find one which will meet all of your requirements.

What if the ground isn’t level? We do not recommend putting underlay directly on top of it because the boards may collapse and disintegrate within a short period. As a result, such a surface must be leveled. Consider purchasing. What is the finest underlay on uneven floors?

Many laminate flooring now comes with underlay cushioning incorporated into the bottom of the surface. You won’t need to buy or install an additional foam cushioning underlayment with any of these products. These flooring components are often laid directly on top of a plywood / OSB foundation. Some varieties can be used in wet environments without the need for a vapor barrier seal.
