Best Underlayment for Laminate (2 Must-Haves!)

Laminate’s popularity has exploded in recent years, and it’s easy to see why. It’s durable, stylish, and often easier on the wallet than hardwood or tile.

But here’s a secret: the real magic behind a long-lasting, comfortable laminate floor isn’t just the planks themselves. It’s the unsung hero underneath: the underlayment.

Think of underlayment as the foundation of your flooring. It’s the layer between your subfloor and your laminate planks, and it plays a HUGE role in how your floor looks, feels, and sounds.

Ever walked on a laminate floor that felt hard, hollow, or echoed with every step? Chances are, the underlayment was lacking.

So, what are the common mistakes homeowners make when choosing underlayment? They often overlook its importance, choosing the cheapest option or not considering their specific needs.

This can lead to a whole host of problems, from moisture damage to annoying noise.

In this article, I’m going to spill the beans on the two essential must-haves for choosing the best underlayment for your laminate flooring.

These two factors will make or break your flooring experience, so listen up!

We’ll be diving deep into:

• Moisture Barrier: Protecting your floor from water damage.
• Sound Absorption: Creating a quiet, comfortable living space.

Trust me, investing in the right underlayment is like buying insurance for your floor. It’s a small price to pay for long-term peace of mind and a beautiful, functional space. Let’s get started!

Section 1: Understanding Underlayment

So, what exactly is underlayment?

Simply put, it’s a thin layer of material installed between your subfloor (the structural floor underneath) and your finished flooring (in this case, laminate).

It acts as a cushion and a barrier, providing a range of benefits that directly impact the performance and longevity of your laminate floor.

Think of it like the shock absorbers in your car – you don’t see them, but you definitely feel the difference when they’re not there!

There are several types of underlayment available on the market, each with its own unique properties:

• Foam Underlayment: This is one of the most common and affordable options. It’s lightweight, easy to install, and provides decent cushioning and sound insulation.

  • Pros: Inexpensive, easy to work with.
  • Cons: Can compress over time, may not be the best for moisture protection.

  • Cork Underlayment: A natural and sustainable option known for its excellent sound absorption and thermal insulation properties. It’s also naturally resistant to mold and mildew.

  • Pros: Eco-friendly, great sound and thermal insulation.

  • Cons: More expensive than foam, can be more difficult to install.

  • Rubber Underlayment: Offers superior sound and impact absorption, making it a great choice for multi-story homes or areas with heavy foot traffic.

  • Pros: Excellent sound and impact absorption, durable.

  • Cons: Can be expensive, may have a rubbery odor initially.

  • Felt Underlayment: Provides a dense, supportive layer that helps to even out minor imperfections in the subfloor. It also offers good sound insulation.

  • Pros: Good sound insulation, helps to even out subfloor imperfections.

  • Cons: Can be more expensive than foam, may not be the best for moisture protection.

How does underlayment interact with laminate flooring?

It’s all about creating a supportive and protective environment. Here’s a breakdown:

• Sound Insulation: Underlayment absorbs impact noise, reducing the echoing and hollow sounds that can be common with laminate floors. This is especially important in apartments or multi-story homes.
• Moisture Protection: Many underlayments have a built-in moisture barrier that prevents moisture from the subfloor from seeping into the laminate planks, which can cause warping, swelling, and mold growth.
• Thermal Regulation: Some underlayments provide a layer of insulation, helping to keep your floors warmer in the winter and cooler in the summer.
• Subfloor Leveling: Underlayment can help to smooth out minor imperfections in the subfloor, providing a more even surface for the laminate to rest on. This prevents the planks from flexing or creaking.

Choosing the right underlayment is crucial for specific environments.

For example, if you’re installing laminate in a basement, which is typically prone to moisture, you’ll need an underlayment with a robust moisture barrier.

If you’re installing laminate in a high-traffic area like a hallway or living room, you’ll want an underlayment that’s durable and can withstand constant wear and tear.

I always tell my clients to think about their specific needs and priorities when choosing underlayment. Don’t just grab the cheapest option off the shelf!

It’s an investment that will pay off in the long run by protecting your laminate floor and enhancing your overall living experience.

Section 2: Must-Have #1: Moisture Barrier

Okay, let’s dive into the first “must-have”: a moisture barrier.

Why is this so important? Well, think about it: your subfloor is often concrete or wood, both of which can absorb and release moisture.

This moisture can then migrate up into your laminate flooring, causing all sorts of problems.

I’ve seen firsthand the devastating effects of moisture on laminate floors. Warping, buckling, swelling, and even mold growth are all potential consequences of neglecting moisture protection.

And trust me, replacing a water-damaged floor is a lot more expensive than investing in a good underlayment with a moisture barrier.

A moisture barrier is a layer of material that prevents moisture from passing through it. It’s typically made of polyethylene film or other waterproof materials.

Some underlayments come with a built-in moisture barrier, while others require you to install a separate layer of plastic sheeting.

Here are some common materials used as moisture barriers:

• Polyethylene Film: This is a thin, flexible plastic sheet that’s typically used as a vapor barrier in construction. It’s an affordable and effective option for blocking moisture.
• Specialized Underlayment Products: Many underlayment manufacturers offer products with a built-in moisture barrier. These products are often more convenient to install and provide a more reliable level of protection.

How do you assess moisture levels in your space?

Before you even think about installing laminate flooring, it’s crucial to assess the moisture levels in your subfloor. Here’s how:

• Moisture Meter: A moisture meter is a handheld device that measures the moisture content of wood or concrete. This is the most accurate way to determine if your subfloor is too damp. You can rent these from most hardware stores.
• Plastic Sheet Test: Tape a square of plastic sheeting to your subfloor and leave it for 24-48 hours. If you see condensation forming underneath the plastic, it means your subfloor is releasing moisture.
• Visual Inspection: Look for signs of water damage, such as stains, discoloration, or mold growth. These are clear indicators that you have a moisture problem.

Ignoring moisture problems can have serious consequences. According to the National Wood Flooring Association (NWFA), excessive moisture is the leading cause of wood flooring failures.

While laminate isn’t wood, it still contains wood byproducts and is therefore susceptible to moisture damage.

“Moisture is the enemy of wood flooring,” says Michael Purser, owner of Rosebud Company and NWFA chairman.

“Controlling moisture before, during and after installation is critical to the long-term performance of any wood floor.”

The same principle applies to laminate flooring.

Practical Tips for Choosing a Moisture Barrier:

• Check the Manufacturer’s Recommendations: Always follow the laminate flooring manufacturer’s recommendations for underlayment and moisture barrier requirements.
• Consider Your Climate: If you live in a humid climate, you’ll need a more robust moisture barrier than if you live in a dry climate.
• Look for a High Perm Rating: The perm rating measures the amount of moisture that can pass through a material. A lower perm rating indicates a better moisture barrier.
• Overlap and Tape Seams: When installing a separate moisture barrier, overlap the seams by at least 6 inches and tape them securely with moisture-resistant tape.

I’ve seen homeowners try to cut corners by skipping the moisture barrier or using a cheap, ineffective one.

Trust me, it’s not worth the risk. Investing in a quality moisture barrier is a small price to pay for protecting your laminate floor from water damage and ensuring its long-term performance.

Section 3: Must-Have #2: Sound Absorption

Alright, let’s talk about the second “must-have”: sound absorption.

Ever walked into a room with laminate flooring and felt like you were in an echo chamber? That’s often due to a lack of sound absorption.

Sound absorption refers to a material’s ability to absorb sound waves, reducing noise levels and creating a more peaceful environment.

This is especially important in multi-story homes, apartments, or any space where you want to minimize noise transmission.

Think about it: footsteps, dropped objects, and even conversations can create a lot of noise that travels through the floor.

Without adequate sound absorption, these noises can be amplified and transmitted to other rooms, disrupting your peace and quiet.

There are several materials that offer sound-absorbing properties:

• Cork Underlayment: As mentioned earlier, cork is a natural sound absorber. Its cellular structure helps to dampen sound waves, reducing noise transmission.
• Thicker Foam Underlayment: Thicker foam underlayment generally provides better sound absorption than thinner options. Look for foam underlayment with a density of at least 3 pounds per cubic foot.
• Rubber Underlayment: Rubber is an excellent sound absorber due to its density and elasticity. It’s often used in commercial settings where noise reduction is a priority.
• Specialized Sound-Dampening Underlayment: Some manufacturers offer underlayment products specifically designed for sound dampening. These products often incorporate multiple layers of different materials to maximize sound absorption.

Impact of Sound Transmission on Daily Living:

Sound transmission can have a significant impact on your daily life. Here are some examples:

• Reduced Privacy: Noise from one room can easily travel to other rooms, reducing privacy and making it difficult to have private conversations.
• Disturbed Sleep: Noise from upstairs can disrupt sleep, especially for light sleepers.
• Increased Stress: Constant noise can be stressful and lead to irritability and fatigue.
• Difficulty Concentrating: Noise can make it difficult to concentrate on work or other tasks.

I once had a client who lived in an apartment building and was constantly bothered by noise from the unit above.

They could hear every footstep, every dropped object, and even conversations. It was driving them crazy!

After installing a high-quality underlayment with excellent sound absorption, they noticed a dramatic difference. The noise levels were significantly reduced, and they were finally able to enjoy peace and quiet in their own home.

How to Test Sound Absorption Capabilities:

Unfortunately, it’s difficult to accurately test sound absorption capabilities without specialized equipment. However, here are some things to look for:

• STC Rating: The Sound Transmission Class (STC) rating measures a material’s ability to block airborne sound. A higher STC rating indicates better sound blocking performance.
• IIC Rating: The Impact Insulation Class (IIC) rating measures a material’s ability to block impact sound, such as footsteps. A higher IIC rating indicates better impact sound insulation.
• Manufacturer Specifications: Check the manufacturer’s specifications for sound absorption performance. Look for products that have been tested and certified by independent organizations.

Recommendations for the Best Sound-Absorbing Underlayment Products:

While I can’t endorse specific brands, I can offer some general recommendations:

• Look for underlayment with a high STC and IIC rating.
• Consider cork or rubber underlayment for superior sound absorption.
• Read online reviews and see what other homeowners are saying about the sound-dampening performance of different products.
• Don’t be afraid to spend a little extra money on a high-quality underlayment. It’s an investment that will pay off in the long run by creating a more peaceful and comfortable living environment.

Choosing the right underlayment for sound absorption can make a world of difference in your home.

It can transform a noisy, chaotic space into a peaceful, relaxing sanctuary.

Section 4: Additional Features to Consider

These features may not be as critical as moisture protection and sound dampening, but they can still enhance the performance and comfort of your laminate floor.

• Thermal Insulation: Some underlayments provide a layer of insulation, helping to keep your floors warmer in the winter and cooler in the summer. This can be especially beneficial in colder climates or in rooms that tend to be drafty.
• Durability: The durability of the underlayment is important, especially in high-traffic areas. Look for underlayment that’s resistant to compression and can withstand constant wear and tear.
• Ease of Installation: Some underlayments are easier to install than others. If you’re a DIYer, you may want to choose an underlayment that’s lightweight and easy to cut and install.

Different lifestyles and home environments may influence the choice of underlayment features.

For example:

• Homes with Pets: If you have pets, you’ll want an underlayment that’s resistant to stains and odors.
• Families with Children: If you have children, you’ll want an underlayment that’s durable and can withstand heavy foot traffic and dropped objects.
• Homes with Radiant Heat: If you have radiant floor heating, you’ll need an underlayment that’s specifically designed for use with radiant heat systems.

Here are some specific scenarios where additional features may be beneficial:

• Basements: In addition to a moisture barrier, you may also want an underlayment with thermal insulation to help keep your basement floor warmer.
• Apartments: In addition to sound absorption, you may also want an underlayment that’s fire-resistant to meet building codes.
• Kitchens: In addition to a moisture barrier, you may also want an underlayment that’s resistant to spills and stains.

Ultimately, the best underlayment for your laminate flooring will depend on your specific needs and priorities.
