Laminate Underlayment: Which Type Is Best? (1 Mistake!)

Have you ever walked into a room with a beautiful laminate floor, only to feel like you’re walking on a drum?

Or maybe you noticed a chill creeping up from the floor, even with the heat on?

What if I told you the secret to a comfortable, quiet, and long-lasting laminate floor isn’t just the laminate itself, but what’s underneath?

That’s right, I’m talking about underlayment.

As a flooring contractor with years of experience, I’ve seen firsthand how crucial underlayment is.

I’ve also seen the mistakes people make when choosing it, and trust me, they can be costly.

In this article, we’ll dive deep into the world of laminate underlayment, exploring different types, their pros and cons, and most importantly, the ONE critical mistake you absolutely must avoid.

Section 1: Understanding Laminate

Flooring and Underlayment

1. What is Laminate Flooring?

Laminate flooring has become a staple in modern homes, and for good reason.

It’s affordable, durable, and can mimic the look of hardwood, tile, or stone.

But what exactly is it?

Laminate is a multi-layered synthetic flooring product fused together through a lamination process.

Typically, it consists of:

A wear layer: This is the top layer that protects against scratches, stains, and fading.
A decorative layer: This layer features a high-resolution image that gives the laminate its realistic appearance.
A core board: This is the thickest layer, usually made of high-density fiberboard (HDF) or medium-density fiberboard (MDF), providing stability and impact resistance.

A backing layer: This bottom layer provides moisture resistance and helps prevent warping.

Compared to traditional hardwood, laminate is more resistant to scratches and dents, making it a great choice for busy households with kids and pets.

And unlike tile, it’s warmer underfoot and easier to install.

2. Role of Underlayment in Flooring Systems

Now, let’s talk about underlayment.

Think of it as the unsung hero of your flooring system.

It’s a thin layer of material installed between the subfloor (the structural floor beneath) and the laminate flooring itself.

But why is it so important?

Underlayment serves several crucial functions:

Sound Absorption: It helps to reduce noise transmission, making your floors quieter to walk on.

Ever heard that hollow echo when walking on laminate? Underlayment can minimize that.

Moisture Barrier: It protects the laminate from moisture rising from the subfloor, preventing warping and mold growth.

This is especially important in basements or areas with high humidity.

Thermal Insulation: It provides a layer of insulation, making your floors warmer and more comfortable, especially during colder months.
Subfloor Leveling: It can help to smooth out minor imperfections in the subfloor, providing a more even surface for the laminate.

Without underlayment, your laminate floor would be noisy, cold, and prone to moisture damage.

Trust me, you don’t want that!

3. Types of Laminate Underlayment

Okay, so now you know why underlayment is important.

But with so many options available, how do you choose the right one?

Here’s an overview of the most common types of laminate underlayment:

Foam Underlayment: This is the most common and affordable type.

It’s lightweight, easy to install, and provides basic sound absorption and moisture resistance.

Cork Underlayment: Cork is a natural, eco-friendly option that offers excellent sound insulation and thermal properties.

It’s also naturally resistant to mold and mildew.

Rubber Underlayment: Rubber underlayment is a premium option known for its durability and superior sound absorption.

It’s often used in commercial settings or high-traffic areas.

Felt Underlayment: Felt underlayment is a dense material that provides good insulation and cushioning.

It’s also a good choice for uneven subfloors.

Each type has its unique features and benefits, which we’ll explore in more detail later.

Section 2: The Importance of Choosing

the Right Underlayment

1. Impact on Performance and Longevity

Choosing the right underlayment can significantly impact the performance and longevity of your laminate floor.

Think of it as building a house: you need a solid foundation to ensure the structure lasts.

The same applies to your flooring.

The right underlayment can:

Reduce Noise: A good underlayment can dramatically reduce the sound of foot traffic, creating a quieter and more peaceful environment.

I’ve seen homes where simply upgrading the underlayment transformed the entire atmosphere.
Protect Against Moisture: Moisture is the enemy of laminate flooring.

The right underlayment will act as a barrier, preventing moisture from seeping up from the subfloor and causing warping, buckling, or mold growth.
Extend the Life of Your Floor: By providing a stable and even surface, underlayment helps to prevent wear and tear on the laminate, extending its lifespan.

On the other hand, using the wrong type of underlayment can lead to a host of problems, including:

Squeaking Floors: This is often caused by friction between the laminate and the subfloor due to inadequate underlayment.
Moisture Damage: If the underlayment doesn’t provide adequate moisture protection, your laminate can warp and become damaged.

Reduced Lifespan: Without proper support and protection, your laminate floor will wear out much faster.

2. Cost vs. Quality

When it comes to underlayment, it’s tempting to go for the cheapest option.

After all, it’s just a thin layer of material, right?

Wrong!

While cost is certainly a factor, it’s important to consider the long-term value of investing in quality underlayment.

Think of it this way: spending a little more upfront on a good underlayment can save you money in the long run by preventing costly repairs or premature replacement of your laminate floor.

I’ve seen homeowners try to save a few bucks on underlayment, only to end up spending hundreds or even thousands of dollars fixing the problems it caused.

Here’s a simple analogy: Would you put cheap tires on an expensive car?

Probably not.

You’d want tires that provide good traction, handling, and longevity.

The same principle applies to underlayment.

3. Common Misconceptions

There are a lot of myths and misconceptions surrounding laminate underlayment.

Let’s debunk a few of the most common ones:

“Any Underlayment Will Do”: This is simply not true. Different types of underlayment are designed for different purposes and environments.

Choosing the wrong one can lead to problems.
“Thicker is Always Better”: While thickness can contribute to sound absorption and cushioning, it’s not the only factor.

The type of material and its density are also important.
“I Don’t Need Underlayment if My Subfloor is Perfectly Level”: Even if your subfloor is perfectly level, underlayment still provides essential moisture protection and sound absorption.
“My Laminate Already Has Attached Underlayment, So I Don’t Need Extra”: While attached underlayment is convenient, it may not provide adequate protection or sound insulation, especially in certain situations.

Consider adding an extra layer of underlayment for added benefits.
