What is Vinyl Plank Flooring Made of? (5 Key Materials Explained)
What is Vinyl Plank Flooring?
When I first started working with vinyl plank flooring, I quickly realized how much it could transform a space. One moment you have a dull, tired floor, and the next — with a few boxes of vinyl planks — you’re looking at a room that feels warm, stylish, and surprisingly durable. For many homeowners and contractors like me, vinyl plank flooring offers a perfect blend of beauty, practicality, and affordability.
So, what exactly is vinyl plank flooring? At its core, it’s a type of synthetic flooring designed to look like natural materials such as hardwood or stone but built to handle everyday life with greater resistance to wear and moisture. Think of it as a carefully layered product where each layer plays a vital role in making the flooring strong, comfortable, and visually appealing.
I’d like to walk you through the five key materials that make vinyl plank flooring what it is. Along the way, I’ll share my experiences—both good and bad—and some data-backed insights that can help you understand why this flooring option has become so popular.
The Five Key Materials in Vinyl Plank Flooring
1. PVC (Polyvinyl Chloride) Core
Let me start with the heart of vinyl plank flooring: the PVC core. This is the thickest layer and provides the essential structure and strength. PVC is a type of plastic known for being both flexible and durable. In my early days as a flooring contractor, I was amazed at how resilient this material was, especially compared to traditional hardwood or laminate.
PVC’s resistance to moisture makes it especially useful in areas prone to spills or humidity—like kitchens, bathrooms, and basements. One of my clients had persistent water damage problems with their hardwood floors in the kitchen. Once we installed vinyl planks with a PVC core, those worries were gone. The floor handled spills without warping or staining.
From an industry standpoint, PVC’s popularity is no surprise. The global sales of vinyl flooring have grown steadily by about 8% annually over the last few years. This growth correlates strongly with the demand for floors that can withstand daily wear and moisture without needing constant maintenance.
But PVC isn’t perfect. It can emit volatile organic compounds (VOCs), especially during manufacturing and shortly after installation. This raised concerns for me in some projects involving young children or people with respiratory issues. That’s why I always recommend using low-VOC-certified products and ensuring proper room ventilation during and after installation.
Did you know? According to a study by the EPA, using low-VOC vinyl products can reduce indoor air pollution by up to 60%, which significantly improves air quality.
2. Wear Layer
Next up is the wear layer — a transparent protective coating that sits on top of the printed design layer. This layer is crucial because it shields the floor from scratches, stains, scuffs, and fading.
I once installed vinyl planks in a busy family room where kids and pets ran around constantly. Thanks to a wear layer around 20 mil thick (which is considered commercial-grade), the floor still looked great after two years without any visible damage. On the flip side, I’ve seen cheaper floors with thinner wear layers (6-8 mil) start showing wear marks within months.
The thickness of this wear layer really matters. The Resilient Floor Covering Institute (RFCI) reports that floors with wear layers above 12 mil tend to last up to 50% longer under heavy use than those with thinner coatings.
Additionally, many wear layers are treated with substances like urethane or aluminum oxide to improve scratch resistance and protect against UV light. This means rooms with lots of windows won’t see their floors fade or discolor as quickly.
A personal note here: I once made the mistake of installing a budget vinyl product without proper UV protection in a sunroom. Within a year, the color faded unevenly, making parts of the floor look worn out while other sections remained bright. That taught me to always match product specifications with the room’s conditions.
3. Printed Design Layer
This layer is where all the magic happens visually. The printed design layer contains high-resolution images that replicate wood grains, stone textures, or tile patterns. Modern digital printing techniques bring these designs to life with incredible detail.
When I started in this industry 15 years ago, vinyl floors looked obviously fake — shiny plastic surfaces that lacked depth or texture. Now? You’d have to get down on your hands and knees to spot the difference between some high-end vinyl planks and genuine hardwood.
The printed layer is protected by the wear layer above it, but it can still face challenges such as fading if exposed to harsh sunlight or chemicals. In one project where clients used harsh cleaning solvents daily without realizing their effects, the design layer began to dull prematurely.
Quality printed layers are usually sealed tightly under wear layers to prevent damage from moisture or abrasion. The technology behind these prints has evolved so much that some planks even include embossed textures matching their visual patterns to give an authentic feel underfoot.
4. Backing Layer
Beneath the PVC core sits the backing layer — a material that stabilizes the entire plank and prevents warping or bending after installation.
Backings are commonly made from fiberglass or composite materials that provide strength without sacrificing flexibility. When I worked on a commercial flooring project for an office space that needed extra durability due to heavy rolling office chairs and foot traffic, we chose vinyl plank flooring with fiberglass backing for added support.
This layer also contributes significantly to sound absorption and insulation. Many homeowners have told me how their vinyl floors feel warmer and quieter than tile or concrete because of this backing.
One issue I’ve encountered with lower-quality backing layers is uneven thickness, which caused uneven floors after installation. That’s why I stress checking product specifications for backing uniformity before buying large quantities.
5. Optional Cushion Layer (Attached Underlayment)
Some vinyl planks come with an attached cushion layer or underlayment for additional comfort and sound control. This cushioning is often made from foam or cork-based materials.
I’ve installed these cushioned planks in apartments where noise reduction was critical because neighbors below were sensitive to footsteps. The difference was noticeable — less echoing and a softer feel when walking.
That said, not every job calls for built-in cushioning. For example, when installing over concrete slabs prone to moisture issues, I prefer using separate moisture barrier underlayments instead of relying on attached cushions.
My Journey: Successes and Challenges With Vinyl Plank Flooring
I’ve installed hundreds of vinyl plank floors over the years — each project teaching me something new about these materials.
One standout success story was helping transform an old coffee shop with cracked tile into a cozy hangout spot using wood-look vinyl planks. The client loved how quickly we completed the job without tearing up existing subfloors — plus how easy it was to clean afterward.
But I’ve also faced challenges.
Once, I worked on a large residential project where uneven subfloors caused planks to buckle and separate soon after installation. That experience hammered home how critical proper subfloor prep is for long-lasting results.
Another time, I recommended a cheaper brand for a rental property only to have it fade unevenly under intense sun exposure within two years — disappointing for everyone involved.
Through these ups and downs, I learned that understanding each material’s role helps prevent common pitfalls — from selecting low-quality products to ignoring environmental factors like sunlight or moisture.
