The Flooring Budget Dilemma: Korlok vs. Opus
When I sat down to plan our Q3 flooring refresh for a 12,000 sq ft commercial space, I had two options on the table from the same brand: Karndean Korlok (the click-lock LVT) and Karndean Opus (the glue-down sheet vinyl). Both are premium products. Both carry the Karndean name. But the total cost picture? Completely different.
Here's the thing: As a procurement manager who's tracked every dollar across six years and $180,000 in cumulative flooring spending, I've learned that unit price is a trap. The real question is: Which system costs less to install, maintain, and replace over a 5-year lifecycle?
Let's break this down across the five cost dimensions that actually matter in a B2B context.
Dimension 1: Material Cost Per Square Foot
At face value, Karndean Korlok generally runs $6.50–$8.50 per sq ft (as of Q2 2024, verified against distributor quotes). Karndean Opus comes in lower: $4.50–$5.50 per sq ft for the sheet material. That's a 30-40% premium for Korlok on material alone.
Simple: Opus is cheaper. Period. But here's the catch: That 40% premium on Korlok includes the click-lock underlayment system (the Korlok pad is integrated). Opus requires a separate underlayment layer—typically $0.80–$1.20 per sq ft for a quality 2mm foam. Suddenly, the per-sq-ft gap narrows.
Verdict: Opus is cheaper upfront, but not by as much as the headline suggests.
Dimension 2: Installation Labor & Complexity
This is where the comparison gets interesting—and where many procurement managers miss the hidden cost.
Korlok (click-lock): Requires a qualified installer. Subfloor prep is critical (must be flat within 3/16" over 10 feet—standard TCA guidelines). Installation time: roughly 1,000–1,200 sq ft per day per experienced crew. Labor rate: $2.50–$3.50 per sq ft.
Opus (glue-down sheet): Requires a specialized installer. The sheet material needs precise cutting, seam welding, and adhesive application. Installation time: slower—maybe 600–800 sq ft per day. Labor rate: $3.50–$4.50 per sq ft.
But here's the kicker: Subfloor prep for glue-down is more demanding. Any moisture or unevenness can cause adhesive failure. We paid an extra $0.60 per sq ft for moisture testing and leveling compound on one Opus project.
Verdict: Korlok wins on labor cost and speed. Opus requires premium labor, which eats into the material savings.
Dimension 3: Maintenance & Cleaning Over 5 Years
This is a dimension most comparisons skip—but I've tracked it in our own system.
- Korlok: Sealed surface. Daily: dry mop or vacuum. Weekly: damp mop with Karndean cleaner. After 3 years, we needed a light buffing to restore sheen in high-traffic corridors. Annual maintenance cost: roughly $0.15 per sq ft (labor + product).
- Opus: Seam-welded surface. Daily: same dry mop. But seams can trap dirt if not maintained. After 18 months, we noticed discoloration at seams in a break room. Required a professional deep clean (cost: $0.30 per sq ft). Annual maintenance: $0.20–$0.25 per sq ft.
Not a huge difference, but over 12,000 sq ft over 5 years? That's a $600–$900 difference in maintenance spend.
Verdict: Korlok is slightly cheaper to maintain, but both are low compared to carpet or tile.
Dimension 4: Repair & Replacement Cost per Incident
Here's where the comparison flips. (I've seen this happen twice.)
Korlok: Individual planks can be replaced. If a plank gets damaged, you cut out a corner and click in a replacement. Cost per repair: roughly $2–$5 per sq ft (material + labor), assuming you have spare planks (always keep 5–10% extra).
Opus: You cannot patch a sheet. If a section is damaged, you replace the entire sheet (which may be 12' x 60'). Cost per repair: easily $200–$500 in material and labor for a small area. And matching the pattern? Good luck if the lot number differs.
In Q2 2023, a forklift scrape in our warehouse damaged a 2-sq-ft section of Opus. The repair cost: $340 (replacing a full 15-sq-ft sheet + labor). Same scrape on Korlok? Would have cost about $12 for two planks and 20 minutes of labor. (Yes, I documented both in my cost tracking system.)
Verdict: Korlok is dramatically cheaper to repair per incident. Opus is a risk in high-traffic or high-damage zones.
Dimension 5: End-of-Life & Replacement Cycle (Total Cost of Ownership)
This is the dimension that surprised me—and it's where a procurement manager earns their pay.
Korlok: Average commercial lifespan: 10–15 years. At end-of-life (say year 12), the planks are removed individually. Disposal cost: minimal—they're recyclable. Replacement: you can replace only the worn areas. Total TCO over 12 years (material + installation + maintenance + repairs): roughly $8.50–$10.00 per sq ft per year.
Opus: Average commercial lifespan: 8–12 years. At end-of-life, the entire sheet must be removed and adhesive scraped. Disposal + labor cost: $1.50–$2.00 per sq ft. Replacement: full removal and reinstallation. Total TCO over 10 years: roughly $7.50–$9.50 per sq ft per year.
Wait—Opus is cheaper on TCO? That surprised me too. But the lower material cost offsets the higher labor and repair costs over a full lifecycle—if you don't have major damage incidents.
Verdict: Opus has a slightly lower TCO over a full lifecycle in low-risk environments. Korlok is the safer bet in high-traffic or damage-prone areas.
So Which Do You Choose? (A Procurement Manager's Cheat Sheet)
After comparing quotes, tracking repairs, and calculating TCO across three projects (two Korlok, one Opus), here's my honest recommendation:
Choose Karndean Korlok if:
- Your space has moderate-to-high foot traffic (corridors, break rooms, open offices)
- You expect occasional damage (forklifts, moving furniture, high heel traffic)
- You want faster installation to minimize downtime (e.g., a retail space that can't close for long)
- You have a maintenance team that can handle basic care
Choose Karndean Opus if:
- You have large, open, low-traffic areas (conference rooms, executive offices, showrooms)
- You have a tight upfront budget (the material savings are real)
- You have access to a specialized Opus installer (rare in some markets)
- You're willing to accept slightly higher repair costs for lower material cost
Our choice: For the 12,000 sq ft project, we went with Korlok after a 3-month vendor comparison (8 vendors, 3 rounds of quotes). Why? Because our projected damage risk over 5 years—based on our own incident tracking—was higher than our initial estimate. The Opus savings would have been wiped out by just two repair incidents. Your mileage may vary if you have a low-damage environment.

“I can only speak to mid-size B2B commercial spaces with moderate foot traffic. If you're a school, hospital, or retail environment with constant heavy traffic, the calculus might be different—you might need a completely different product like Karndean Knight Tile or a commercial-grade sheet vinyl.”
