What is Under Linoleum Flooring? (5 Secrets You Didn’t Know!)

I’ve spent years working with different flooring materials, and one thing that always surprises people is how much the right underlayment can affect noise reduction. When you’re walking around on linoleum, the sound your footsteps make isn’t just about the surface itself—it’s also about what’s underneath. I remember one project where a client was frustrated with the echoey noise in their kitchen. We swapped out the existing underlayment beneath their linoleum, and suddenly, the whole room felt quieter and cozier. That got me thinking: what exactly is under linoleum flooring, and why does it matter so much?

What Is Under Linoleum Flooring?

So, what is under linoleum flooring? At its core, the layer beneath linoleum serves as a foundation and cushion. Typically, it’s called an underlayment. This can be made from various materials designed to provide stability, moisture protection, and yes—noise reduction.

The most common types of underlayment under linoleum include:

• Plywood or Particleboard: A rigid base that offers structural support.
• Cork: Natural material known for sound absorption and insulation.
• Foam or Rubber Pads: Soft layers that reduce impact noise and add comfort.
• Asphalt Felt Paper: Used as a moisture barrier in some installations.
• Self-leveling Compounds: Applied on uneven subfloors to create a flat surface.

Each option has its pros and cons depending on what you want from your floor. For instance, cork underlayment is excellent if noise reduction and warmth are priorities, but it might be pricier than foam options. On the other hand, plywood offers great stability but adds little in terms of sound dampening.

Why Noise Reduction Matters with Linoleum Flooring

Have you ever walked across a linoleum floor and noticed how “hollow” or loud your footsteps sound? Linoleum itself is a hard surface; it doesn’t absorb sound well. Without proper cushioning below, every step can echo, especially in rooms with bare walls or high ceilings.

When I first started installing linoleum floors, I had a couple of clients complain about “footstep noise” right after installation. It wasn’t that the linoleum was faulty—rather, they had either no underlayment or used just plywood. That’s when I realized how vital the layers underneath are for a comfortable living environment.

Noise isn’t just an annoyance. Studies show that excessive noise inside homes can increase stress levels and reduce overall comfort. According to data from the World Health Organization, noise above 55 decibels during the day can cause health issues like increased heart rate and difficulty concentrating. So quiet floors contribute to better well-being.

Comparing Different Underlayment Options I’ve Tried

Over the years, I’ve experimented with several underlayment materials beneath linoleum to find the best mix of durability, comfort, and noise control. Here’s a quick rundown of what I learned:

1. Plywood Base

Using plywood as an underlayment is pretty straightforward. It’s strong and helps prevent linoleum from cracking or shifting. However, plywood doesn’t do much for noise reduction. If you’re someone who wears hard-soled shoes indoors or has kids running around, expect some echoing.

On one renovation job in a townhouse, we installed linoleum over a plywood subfloor without additional cushioning. The floor looked great but sounded like a drum when walked on. The client was surprised because they thought plywood would be enough.

2. Cork Underlayment

Cork has been a favorite in many projects because of its natural sound-absorbing qualities. It’s slightly springy underfoot and reduces footfall noise significantly. Plus, cork is environmentally friendly, which appeals to many homeowners today.

One interesting case was a library I worked on where the client wanted minimal noise from footsteps. After installing cork beneath linoleum, the decibel levels dropped by about 15%, which was impressive.

Cork also has thermal insulation benefits—keeping floors warmer in winter and cooler in summer. It resists mold and mildew too since it naturally repels moisture to some extent.

3. Foam or Rubber Pads

Foam underlayment is lightweight and easy to install. It’s good at softening the impact of walking, but cheaper foam can compress over time, reducing its effectiveness.

Rubber pads are more durable and provide excellent sound insulation but come at a higher cost.

I once replaced an old foam layer with rubber pads in a busy daycare center’s linoleum flooring. The difference in noise control was noticeable immediately.

Foam tends to be cost-effective for residential use but may not hold up well under heavy traffic areas compared to cork or rubber.

4. Asphalt Felt Paper

This material acts mainly as a moisture barrier rather than noise control. It’s useful in basements or areas prone to dampness but offers no cushioning.

In one basement installation I supervised, asphalt felt was layered beneath linoleum over concrete to prevent moisture issues. It did its job perfectly but didn’t help with sound at all.

5. Self-Leveling Compounds

While not an underlayment in the traditional sense, these compounds create a flat surface for linoleum installation on uneven subfloors.

They don’t impact noise but are crucial for preventing damage to the linoleum over time.

In one case with an older home where the concrete slab was uneven, applying self-leveling compound before laying the linoleum prevented cracks that would have otherwise appeared within months.

Why Does Underlayment Matter So Much?

You might wonder: isn’t linoleum itself enough? Well, linoleum is a solid surface—durable but somewhat hard and noisy when walked on without cushioning underneath.

The right underlayment does several things simultaneously:

• Noise Control: Reduces footfall sounds and echoes.
• Moisture Protection: Prevents damage from dampness coming from below.
• Comfort: Adds a slight cushion for walking comfort.
• Longevity: Helps prevent cracks and extends flooring life.
• Temperature Regulation: Some materials help insulate against cold floors.

In one home renovation I did, skipping a proper underlayment led to creaking noises after just six months. Adding cork later resolved this issue entirely.

Detailed Data on Noise Reduction with Underlayment

To give you some numbers based on studies and my own observations:

Notice how cork and rubber stand out for noise reduction but come at higher costs. Balancing budget and performance can be tricky.

In my experience working on dozens of projects across different budgets, investing slightly more upfront on quality underlayment like cork or rubber often saves money long term by reducing complaints and floor repairs.

Personal Story: Choosing Underlayment for My Own Home

When I decided to redo the kitchen floor in my house with linoleum, I wanted something quiet and comfortable. Initially, I went with plywood alone—thinking it was enough for support. But every time my kids ran around, the noise echoed loudly.

After some research and testing samples, I switched to a cork underlayment. The difference was night and day. The kitchen felt warmer, softer underfoot, and way quieter. The investment paid off because it transformed how we enjoy the space.

I learned that sometimes cheaper isn’t better if comfort is important to you—and this applies especially to flooring layers you don’t see but feel every day.

Five Secrets About What’s Under Linoleum Flooring You Might Not Know

Here are five secrets I’ve picked up over time:

Secret 1: Not All Subfloors Are Equal

The type of subfloor beneath your underlayment—whether concrete, plywood, or OSB—affects what underlayment you should choose.

Concrete requires moisture barriers; plywood needs sturdier bases.

One time on a concrete slab project without any moisture barrier beneath the linoleum led to bubbling after heavy rainstorms due to trapped moisture—something that could have been avoided with proper layering.

Secret 2: Thickness Matters

Thicker underlayments usually mean better sound absorption but can complicate door clearances or transitions to other flooring types.

I had a client complain after installation because their doors wouldn’t close properly due to an overly thick cork layer plus linoleum thickness combined. This meant trimming doors—a hassle if planned poorly.

Secret 3: DIY vs Professional Installation

Some underlayments like foam are easy for DIYers to install; cork or rubber pads often need professionals for proper fitting and avoiding issues like bumps or gaps.

I encourage clients who want quiet floors but no installation headaches to hire pros—there’s more than meets the eye when installing multiple layers correctly.

Secret 4: Environmentally Friendly Options Exist

Cork is renewable; some foam pads are made from recycled materials.

For eco-conscious homeowners like myself, these choices make a difference beyond just performance.

Secret 5: Underlayment Can Affect Linoleum Adhesion

Certain materials may interfere with glue or adhesive used for linoleum installation.

Always check manufacturer guidelines carefully—using incompatible underlayments can cause peeling or bubbles down the line.

Moisture Control: The Silent Enemy Beneath Floors

Linoleum is sensitive to moisture coming up from below because it’s natural material derived from linseed oil mixed with other substances.

If moisture penetrates from concrete slabs or damp basements without barriers:

• The linoleum can warp or blister.
• Adhesives may fail.
• Mold or mildew can develop underneath causing health risks.

In one basement kitchen project I worked on recently, we layered polyethylene sheeting beneath cork underlayment before applying linoleum tiles. This combo prevented mold growth completely over three years of monitoring—a big relief for the homeowner.

How Do You Pick the Right Underlayment?

Ask yourself these:

• How much foot traffic will this floor see?
• Is noise reduction a priority?
• What’s my budget for underlayment?
• Do I have moisture issues in this area?
• Am I installing over concrete or wood subfloor?

Answering these helps narrow down materials effectively.

If you want a quiet floor for an apartment or office space with lots of foot traffic—rubber pads might be worth it despite higher costs.

For residential kitchens or bedrooms where warmth matters—cork often wins out.

If budget is tight and moisture isn’t an issue—foam might suffice temporarily but expect replacement sooner than later.

A Case Study From My Work

I recently worked on a small office renovation where reducing noise was key for productivity. We installed rubber pad underlayment beneath commercial-grade linoleum tiles.

Before installation, ambient noise from footsteps averaged 70 dB (decibels).

After installation, it dropped to about 52 dB—a significant improvement that satisfied the client completely.

The total cost was higher than foam alternatives but justified by long-term comfort and acoustic benefits.

This project reinforced how investing in quality underlayment pays off especially in commercial environments where noise distractions impact work quality directly.

Installation Tips That Make All The Difference

When installing underlayment beneath linoleum:

• Ensure subfloor is clean & dry: Any debris or moisture will affect adhesion.
• Use recommended adhesives: Some require specific adhesives compatible with both linoleum & chosen underlayment.
• Allow acclimation time: Let materials sit in room temperature before installation to avoid shrinkage or expansion issues.
• Seal seams carefully: Prevent moisture intrusion at joints.
• Check thickness compatibility: Doors & thresholds must accommodate new floor height.

One mistake I often see is rushing installation without proper prep—it leads to bubbling, peeling, or uneven surfaces quickly after installation.

Maintenance Tips for Linoleum and Its Underlayment

Linoleum floors with good underlayment last longer if cared for properly:

• Avoid excessive water spills to prevent moisture seeping through.
• Use felt pads on furniture legs to reduce impact damage.
• Periodically check edges for lifting or bubbling which may indicate adhesive or underlayment issues.
• Clean with pH-neutral cleaners to avoid damaging surface or layers below.

Taking care of your floor means protecting both visible linoleum and invisible layers underneath—don’t overlook either!

My Final Thoughts on What Lies Beneath Your Linoleum

What’s under your linoleum is just as important as the surface itself—sometimes more so. The right underlayment can solve noise problems, protect against moisture, add comfort, and extend the life of your floor.

If you’re planning a new linoleum floor or replacing an old one, take some time to explore your underlayment options carefully.

Don’t hesitate to combine materials if needed (like layering moisture barriers with cork).

And if noise bothers you at all, investing in quality underlayment pays off quickly—even if upfront costs feel steep now.
