What is Karndean Flooring Made Of? (5 Key Materials Explained)

Smart homes are getting smarter by the day. From voice-controlled lights to automated temperature control, technology is changing the way we live. But have you ever stopped to think about the floors beneath your feet in all this innovation? Floors are often one of the most overlooked features in smart home design, yet they deserve just as much attention. That’s why when I started hearing about Karndean flooring—a brand that combines style, durability, and practicality—I had to dig deeper.

I want to share everything I’ve learned about what Karndean flooring is made of and why it’s become a favorite among homeowners looking for a smart, stylish flooring solution.

What Is Karndean Flooring Made Of?

Karndean flooring is luxury vinyl flooring (LVF) designed to mimic natural materials like wood and stone. Unlike traditional hardwood or tile, Karndean is engineered from a combination of synthetic and natural materials that make it durable, waterproof, and easy to maintain—all while looking incredibly authentic.

What really makes Karndean unique is the sophisticated layering and choice of materials used during manufacturing. From my experience working on various flooring projects, understanding what goes into the product helps you appreciate its performance and longevity.

Let’s break down each of the five key materials that make up Karndean flooring:

1. Vinyl (Polyvinyl Chloride or PVC) – The Core Material

Vinyl is the backbone of Karndean flooring. It’s a man-made polymer known for its versatility and durability. The vinyl layer in Karndean isn’t just any vinyl; it’s specially formulated to be resilient while maintaining flexibility.

Depending on the product line, the vinyl core thickness can range from 2mm in LooseLay products up to 5mm in the Korlok rigid core planks. This thickness plays a crucial role in how the floor feels and performs. Thicker vinyl means better impact absorption and resistance to dents.

In one project I managed in Seattle, the client chose Karndean Korlok because their toddler was prone to dropping toys. The 5mm vinyl core absorbed impacts so well that no visible dents appeared after months of use.

The vinyl also provides waterproof properties. Unlike hardwood or laminate that can swell or warp when exposed to moisture, Karndean’s vinyl core remains stable in humid environments or even occasional spills.

Vinyl Composition & Manufacturing

Karndean sources high-quality PVC resin mixed with plasticizers to create a flexible yet tough material. Plasticizers are additives that prevent PVC from becoming brittle. This blend ensures the vinyl core can endure foot traffic without cracking.

The manufacturing process uses calendering and extrusion techniques to create uniform vinyl sheets or planks. These sheets are then layered with printed designs and protective coatings for the final product.

2. Polyurethane Coating – The Tough Protective Layer

On top of the vinyl core lies a transparent polyurethane coating that acts as a shield against wear and tear. This coating protects against scratches, stains, scuffs, and UV damage.

Depending on the collection, this wear layer can range from 0.3mm to 0.7mm thick. For example, the Karndean Da Vinci range includes a 0.55mm wear layer designed for residential spaces with heavy foot traffic.

This coating also contains ceramic bead technology—tiny beads embedded in the surface that enhance scratch resistance further.

During an installation at a busy daycare center in Chicago, I observed how this protective layer prevented damage from constant running and toy dropping over six months. The floors still looked new without requiring any refinishing.

Another feature is that this wear layer is easy to clean without special chemicals—just regular sweeping and damp mopping keep it spotless.

3. Glass Beads – Stability Enhancers

You might not realize it, but microscopic glass beads are integrated within the vinyl layers. These beads add rigidity and stability by reducing expansion and contraction caused by temperature fluctuations.

This is especially important in climates with wide seasonal temperature swings—like where I live in Minnesota—where wood floors often develop gaps or warping due to humidity changes.

Glass beads help maintain a flat surface by reinforcing the vinyl’s structural integrity.

Manufacturers typically add these beads during the mixing phase of the vinyl compound to ensure even distribution throughout the layer.

4. Composite Backing Layer – The Support System

Beneath the vinyl core is a composite backing layer made from recycled materials combined with natural fibers like cork or wood flour.

This backing provides dimensional support, sound insulation, and added comfort underfoot. Cork-backed Karndean products are popular because they offer natural warmth and noise reduction benefits.

In one home renovation I did in Denver, installing cork-backed Karndean resulted in noticeably quieter footsteps compared to laminate floors previously installed.

The backing thickness varies but usually falls between 1mm and 3mm depending on product design.

5. Natural Mineral Fillers – Enhancing Texture & Density

Mineral fillers such as calcium carbonate are mixed into the vinyl formulation to increase density and replicate textures found in natural materials like wood grain or stone surfaces.

These fillers make the floor feel more substantial and realistic underfoot compared to thinner, hollow-feeling vinyl products.

They also contribute to durability by reinforcing the vinyl matrix against wear.

From conversations with Karndean reps, I learned that these fillers are carefully calibrated based on the design style. For instance, floors mimicking rugged stone have a rougher texture thanks to these mineral additives.

How Karndean Flooring Is Made: A Step-by-Step Overview

Understanding how these materials come together helps clarify why Karndean floors perform so well:

1. Vinyl Layer Production: High-grade PVC resin mixed with plasticizers and mineral fillers is formed into sheets or planks.
2. Printing: Using high-definition printing technology, realistic wood grains or stone patterns are applied onto the vinyl surface.
3. Protective Coating: A polyurethane wear layer containing ceramic beads is applied on top.
4. Backing Attachment: Composite backing layers with cork or other materials are laminated underneath.
5. Cutting & Finishing: Planks or tiles are cut to size with precision.
6. Quality Control: Finished products undergo testing for thickness, wear resistance, slip resistance, and color accuracy.
7. Packaging & Shipping: Ready for installation worldwide—from Europe to North America.

Detailed Cost Breakdown

When my clients ask about Karndean flooring costs, I break it down into material and installation:

For example, a typical 1,000 sq ft kitchen + living area project might cost between $9,000 and $18,000 including installation.

Compared to hardwood floors ($8-$15 material + $6-$10 installation), Karndean is competitive but offers advantages like waterproofing and easier maintenance.

Maintenance Tips Based on Material Composition

Karndean’s material makeup makes upkeep simple but here’s what I recommend:

• Regular Cleaning: Sweep or vacuum weekly to remove dirt particles that could scratch.
• Mopping: Use damp mop with mild cleaner; avoid abrasive tools or harsh chemicals.
• Protective Pads: Add felt pads under furniture legs to prevent indentations.
• Spill Management: Wipe spills immediately—vinyl core resists water but prolonged exposure isn’t ideal.
• Avoid Direct Heat Exposure: Keep heat sources like radiators away as excessive heat can soften polyurethane coatings.
• UV Protection: Use curtains or blinds if floors receive intense sunlight for prolonged periods to prevent fading despite UV-resistant coatings.

Clients often ask how Karndean compares with laminate or hardwood for maintenance:

Comparing Karndean With Other Flooring Options

I often get asked whether Karndean is worth it compared to hardwood or laminate.

Hardwood vs Karndean:

• Hardwood feels warm and authentic but is vulnerable to water damage.
• Karndean mimics hardwood looks but offers waterproofing and easier maintenance.
• Hardwood requires refinishing every few years; Karndean does not.
• Hardwood is pricier ($8-$15 material + $6-$10 install) versus Karndean ($6-$12 + $3-$6).

Laminate vs Karndean:

• Laminate is generally cheaper but less water-resistant.
• Laminate tends to have hollow sounds underfoot; Karndean feels more solid.
• Karndean offers more realistic textures due to mineral fillers.
• Laminate can swell if exposed to moisture; Karndean won’t warp.

In my experience helping dozens of clients choose floors, those wanting durability plus style lean toward Karndean as a balanced choice.

How Long Does Karndean Flooring Last?

With proper care, Karndean flooring typically lasts between 15 to 25 years.

The polyurethane coating protects against scratches while the vinyl core prevents warping—a common issue with other flooring types over time.

I know a couple who installed Karndean in their Florida home over 20 years ago—the floor still looks great despite kids and pets running around daily!

Installation Insights From My Projects

Installation methods vary depending on product type:

• LooseLay: Uses a non-glue system allowing planks to be laid directly over existing floors.
• Glue Down: Adhesive applied directly to subfloor for solid placement.
• Click System (Korlok): Interlocking planks snap together for floating floor installation.

I usually recommend LooseLay for DIYers due to simplicity but Korlok offers better sound insulation for larger homes.

Preparation is key—make sure subfloors are clean, dry, and level before installation.

Environmental Impact & Sustainability

Karndean has made strides in sustainability:

• Use of recycled content in backing layers reduces waste.
• Low VOC emissions contribute to healthier indoor air quality.
• Some collections include cork backing sourced from sustainable forests.

When I discussed this with one of their reps at a trade show, they emphasized continual improvements toward greener manufacturing processes.
