What Is Underlayment?
Underlayment is a thin layer of material—typically foam, felt, cork, or rubber—installed between your subfloor and the laminate flooring planks. While it might seem small, it serves several essential functions that directly impact your flooring's performance and daily comfort.
Cushioning and Comfort
Laminate flooring is a floating floor, which means it isn’t nailed or glued directly to the subfloor. Because of that, having a buffer layer makes every step feel softer and more comfortable. Without underlayment, laminate floors can feel hollow, noisy, and hard underfoot. Especially in high-traffic areas, a cushioned underlayment reduces foot fatigue and adds a more pleasant walking experience.
Moisture Protection
Underlayment with a built-in moisture barrier can protect your laminate flooring installation from potential damage caused by spills, leaks, or vapor from the subfloor. This is particularly important in areas like kitchens, bathrooms, or basements where moisture is more likely. Without proper protection, moisture can seep into your laminate planks, leading to warping, swelling, and premature failure.
Sound Absorption
One of the common complaints about laminate floors is the sound they make—clicking, tapping, or hollow echoes with every step. Installing laminate flooring with the proper underlayment significantly reduces sound transmission in the room and to the floor below, making your home quieter and more enjoyable.
Subfloor Imperfection Correction
Even a slightly uneven subfloor can result in a bumpy laminate surface. Quality underlayment helps to smooth out minor imperfections, creating a level and stable foundation for your laminate floor installation. This ensures better performance and reduces the chances of planks shifting or separating over time.
Thermal Insulation
If you're installing laminate over a concrete subfloor or in a colder space, underlayment helps maintain a more consistent temperature underfoot. Certain underlayments even provide energy efficiency by reducing heat loss through the floor, a bonus for comfort and cost savings.
