LVT is the most popular floor type in Central Ohio right now, and for good reason — it's waterproof, durable, realistic-looking, and installs fast. But walking into a flooring store or scrolling product pages, you're hit with a wall of specs: 12 mil wear layer, SPC core, AC4 rating, 6mm total thickness, EIR texture.
Here's what each of those actually means in plain language, and which ones matter most when you're making a buying decision.
The Wear Layer — The Number That Matters Most
The wear layer is the clear protective coating on top of the decorative design. It's measured in mil (1 mil = 0.001 inch). This is the spec that determines how long your floor will look good under real-life foot traffic, pet nails, and furniture.
Core Type: SPC vs. WPC
Modern LVT uses one of two core constructions. Both are waterproof — the difference is in rigidity and feel underfoot.
- Rigid, dense core (limestone powder + PVC)
- Better for concrete subfloors — bridges minor imperfections
- More dimensionally stable in temperature swings
- Harder underfoot — usually paired with underlayment
- Most common type for below-grade installation
- Foamed core, less dense, softer underfoot
- Built-in underlayment common
- Better acoustic performance (quieter foot traffic)
- Less rigid — better over existing resilient floors
- Not recommended for basement/below-grade slabs
For most Columbus homes — especially those with concrete subfloors or basements — SPC is the better choice. It handles temperature fluctuation and is the standard spec for below-grade installations.
AC Rating: Abrasion Class
The AC rating system (AC1–AC5) comes from the European standard EN 13329 and measures resistance to surface abrasion. It's more commonly referenced with laminate, but LVT products use it too.
- AC1–AC2: Light residential. Bedrooms, closets. Not for main living areas.
- AC3: General residential. Living rooms, dining rooms, home offices.
- AC4: Heavy residential / light commercial. Kitchens, hallways, open-concept main floors. Good choice for most Columbus homes.
- AC5: Heavy commercial. Restaurants, retail. Overkill for home use but maximum durability.
What "Waterproof" Actually Means
Every LVT product advertises itself as waterproof. Technically, it's true — the vinyl plank itself won't absorb water or swell. Spill a glass of wine, leave it for hours, wipe it up, floor is fine.
What waterproof doesn't mean: the floor protects your subfloor from moisture migrating upward from below. If you're installing on a wet concrete slab or in a basement with active moisture, the LVT plank stays fine — but the subfloor below it can still be damaged, and mold can grow in the gap between the plank and the slab. Test and address moisture before you install, not after.
Installation Method: Click-Lock vs. Glue-Down vs. Loose-Lay
- Planks snap together, float over subfloor
- No adhesive required
- Faster install, easier replacement of damaged planks
- Slight movement and sound possible at joints
- Best for most residential installs
- Full-spread adhesive to subfloor
- Zero movement, quieter underfoot
- More stable in large open areas
- Harder to repair individual planks
- Better for commercial or very large rooms
For most Columbus homes, click-lock is the right choice. The install is faster, individual planks can be swapped if something goes wrong, and with a quality SPC product the stability is excellent. Glue-down is primarily a commercial or high-traffic application.
Total Thickness and Underlayment
Total LVT thickness ranges from about 4mm (thin, entry-level) to 12mm (premium). The core of that number is the SPC or WPC layer — the wear layer adds only about 0.3–0.5mm on top.
Thicker floors feel more substantial underfoot, cover minor subfloor imperfections better, and have better acoustic properties. For a main living area on a concrete slab, 6–8mm SPC is the sweet spot. Thinner products (4–5mm) are better suited to wood subfloors where they're well-supported.
Many products come with a pre-attached underlayment pad. If yours doesn't, a 1–2mm foam underlayment over concrete adds comfort and a small noise benefit. Don't go thicker than 2mm — it allows the floor to flex too much at the joint.
EIR Texture: The Realism Factor
EIR stands for Embossed-In-Register — it means the surface texture is digitally aligned with the printed wood grain design beneath it. Knots, grain lines, and texture match up exactly, the way real wood looks. Non-EIR products have a generic emboss that's visibly out of sync with the print.
If you're choosing LVT because you want it to look like hardwood, EIR texture is the single biggest visual upgrade. It's available in mid-tier and above products — generally anything priced at $2.50+/sq ft for the material.
Frequently Asked Questions
What wear layer thickness do I need for a family home?
12 mil is the minimum for a busy household. If you have dogs or heavy traffic, go 20 mil. The cost difference is small and the durability difference is significant — especially under pet nails.
What does "waterproof" actually mean for LVT?
The LVT plank itself won't absorb water or be damaged by spills. But "waterproof" doesn't protect the subfloor from moisture migrating up from below. Always test and address subfloor moisture separately — especially in basements and on-grade slabs.
Click-lock vs. glue-down — which is better?
For most Columbus homes, click-lock. It floats over the subfloor, installs faster, and individual planks can be replaced if needed. Glue-down is preferred in very large commercial spaces or high-traffic settings.
What AC rating do I need for residential use?
AC3 for light-use rooms, AC4 for main living areas, kitchens, and hallways. AC5 is commercial-grade and overkill for home use, though it provides extra longevity in very high-traffic spots.
Is LVT the same as LVP?
Same core technology, different formats. LVT typically refers to tile-format products (stone, square looks), LVP to plank formats (wood looks). The specs — wear layer, core type, AC rating — apply the same way to both.
