How to Tell If Your Luxury Vinyl Plank Flooring Is Actually High Grade

Two vinyl planks can look almost the same in a showroom. One lasts ten years. The other lasts twenty-five. The difference is not the color. It is the grade.

Grade is not a marketing word. It is a real classification, built from four things: wear layer thickness, core material, backing construction, and warranty terms. This guide breaks down what actually determines the best grade of luxury vinyl plank flooring, so you can compare planks by spec instead of price tag.

We will cover how LVP grading works, the specs that matter most, and what to check in person before you buy.

What Is the Best Grade of Vinyl Plank Flooring?

The best grade of luxury vinyl plank flooring has a wear layer of 20 mil or thicker, a rigid SPC or WPC core, and a warranty that matches how hard your household uses the floor. Grade comes down to four factors. Those are wear layer thickness, core material, backing construction, and installation rating.

Higher-grade planks resist scratches, dents, and moisture longer than lower-grade planks.

How Is Luxury Vinyl Plank Actually Graded?

Luxury vinyl plank is tested and rated for residential, light commercial, or commercial use. Each rating reflects a different amount of daily traffic the plank can handle.

These ratings are not made up by manufacturers. ASTM International sets the testing standards behind them. ASTM F1700 classifies solid vinyl tile by type and grade. ASTM F3261 covers rigid-core SPC and WPC vinyl products specifically.

A higher price tag does not always mean a higher grade. Some planks are priced for their color or texture, not their performance specs. See our full cost breakdown by material type to see what you should actually expect to pay. A side-by-side comparison of samples, checked for wear layer and backing, is the most reliable way to feel the difference before you decide.

The 4 Specs That Determine Grade

Four specs decide where a plank lands on the grade scale. Check each one before you compare price.

Wear Layer Thickness

The wear layer is the clear top coat that protects the plank. It is measured in mils, or thousandths of an inch.

• 6–12 mil: entry-level residential. Fine for low-traffic rooms like bedrooms.
• 20 mil: the higher grade tier for active households with kids or pets. Also rated for light commercial use.
• 28 mil and up: full commercial grade, built for heavy foot traffic.

Wear layer and plank thickness are not the same thing. See our full thickness guide by room to pair the right mil rating with the right mm thickness for your space.

Core Material

The core is the rigid layer beneath the wear layer. Most high-grade LVP uses SPC or WPC.

SPC cores are denser and sturdier underfoot. WPC cores feel softer and hold heat better. Both are fully waterproof, which is why grade depends more on the wear layer and backing than the core alone. Compare LVP durability to other floor types if you're weighing it against tile or hardwood.

Backing Layers

Backing affects comfort, sound, and moisture resistance. A cushioned backing adds warmth and cuts down on noise between floors.

A rigid backing skips the cushioning but often pairs with a thicker overall plank. Some rigid-backing planks include an attached underlayment already built in.

Installation Method Style

Grade also connects to how the plank goes down. Click-lock, floating installation works across most residential grades.

Glue-down installation is more common in commercial-grade settings. It holds up better under rolling loads, like carts or heavy furniture.

What High-Grade Vinyl Plank Should Include

A few specs separate a truly high-grade plank from an average one. Look for these before you buy:

• A waterproof core, not just a water-resistant surface
• A wear layer of 20 mil or thicker for busy households
• A warranty that reflects heavier residential or light commercial use
• Testing to ASTM F1700 and F3261 standards, listed on the spec sheet

If a plank checks every box above, it will handle daily life without showing wear too soon.

How to Verify Grade Before You Buy

Specs on paper are one thing. Here is how to confirm them in person before you commit.

1. Ask for the spec sheet, not just the sample. A sample shows color and texture, not wear layer or core rating.
2. Get the warranty in writing. Residential warranties often run longer than commercial ones, since commercial floors see far more daily traffic.
3. Compare two or three planks side by side. Grade differences are easier to feel than to see.
4. Watch for planks marketed as premium but tested only to residential standards. A mismatch between marketing and tested grade is a mistake worth watching for.

Find High-Grade Luxury Vinyl Plank in Spokane

Grade comes down to four things: wear layer, core, backing, and warranty. Check all four before you buy.

Spokane winters run cold, and indoor heating pulls humidity well below 30%. Summers are warm and dry. That swing in temperature calls for a stable core, since a lower-grade core can shift over time under those conditions. A rigid SPC or WPC core built to ASTM F3261 standards holds up better through Spokane's seasons.

Ask to see the spec sheet on any plank you're considering, not just the sample. That is the fastest way to know you are getting the grade you are paying for. Pro Floors and Blinds carries graded LVP options built for Spokane's climate, and you can browse our full wood and laminate flooring supply to compare LVP against hardwood and laminate side by side.
