Overview
Pulled from the rack at our Santa Clara showroom, the St. Lawrence sample reads as a weathered warm brown with golden honey undertones — the kind of multi that shifts subtly under different bulb temperatures without ever pulling off-character. The plank surface shows smooth low-relief surface, even board-to-board deep register, very few visible knots, narrow 7-inch width, with minimal-knot, refined character that tracks across the run rather than repeating on a printed cycle. The tight vertical grain with refined figure runs in steady linear sweeps rather than the busy swirl pattern lower-tier printed-vinyl tends toward. Held under our gallery LED at midday, the reads true instead of flickering between cool and neutral the way thinner LVT prints often do. The mood is refined, which is what customers most often say when they set the sample down beside a cabinet door, paint sample card, or tile they brought in. Built on an 7mm WPC core with attached 1mm IXPE acoustic pad — 8mm total assembly. 100% waterproof core. 20 mil commercial-grade wear layer. FloorScore certified.

Why homeowners choose it
✔
Color & pairing. In the install photo our supplier shipped, St. Lawrence sits beneath warm cream walls and white painted built-in and millwork cabinetry — the multi tone carries the floor without competing for attention. That’s what we look for when matching St. Lawrence to cabinet, paint, or tile samples in our showroom.
✔
Thickness & core. The 8mm total plank thickness combines the rigid WPC core with the attached acoustic pad in a single factory-bonded stack. Noticeably firmer and quieter underfoot than thinner WPC at the same step. 100% waterproof — safe for every room including kitchens, bathrooms, basements, and laundry rooms.
✔
Wear layer & finish. The 20 mil commercial-grade wear layer is rated for kitchens, entryways, and pet households — tested for chair legs, pet claws, and daily mop-and-go cleaning. FloorScore certification confirms emissions meet CDPH/EHLB v1.2-2017 — California’s strictest indoor air standard, LEED + WELL accepted, GreenPoint Rated qualifying. Safe for families with infants, asthma, or chemical sensitivities — tested annually by SCS Global.
✔
Acoustic pad. The attached 1mm IXPE acoustic underlayment arrives factory-bonded to the WPC core, ready to install over the subfloor — no separate purchase, no extra-underlayment decisions. The attached pad is the only approved underlayment under the manufacturer warranty; installing additional pad above or below voids the warranty (the plank itself remains physically waterproof regardless). Dampens footfall noise throughout the home.
✔
Surface & edge. Close inspection of St. Lawrence reveals smooth low-relief surface, even board-to-board deep register, very few visible knots, narrow 7-inch width — what actually distinguishes premium WPC from printed-vinyl tier. The tight vertical grain with refined figure catches light directionally; the minimal-knot, refined character of scattered pin knots (under ¼-inch) reads as authentic floor texture, not flat-printed pattern. That’s what makes the floor read as wood at 5 feet rather than vinyl at 18 inches.
✔
Locking & grade. Installs over wood, concrete, or existing hard flooring. No adhesive, no acclimation wait, DIY-friendly with a tapping block. St. Lawrence’s Unilin Uniclic system plus 8mm rigid build works above, on, and below grade — basement to second floor, no construction-type restrictions.
✔

Installation & care
Below are Paradigm’s manufacturer specifications plus installer best-practice notes (author byline at top of page). Paradigm’s warranty follows manufacturer spec; real-world installation often benefits from the extra steps below.
Acclimation:
Acclimate sealed cartons 48+ hours at normal room conditions before install.
Pro tip: If boxes have been stored in a cold truck or warehouse below 50°F, let them sit in the install room for 24 hours before cutting. Rigid-core planks tolerate temperature change better than wood, but extreme cold can make the click-lock edges brittle during installation.
Subfloor flatness:
Subfloor must be dry, sound, flat to 3/16-inch over 10-foot radius. Concrete fully cured.
Pro tip: On older concrete slabs, we measure flatness in multiple directions — not just one straight line. A 3/16-inch dip in a 2-foot circle under a refrigerator telegraphs through even the thickest WPC eventually, regardless of what the 10-foot average says.
Moisture testing (concrete):
Test concrete subfloors per ASTM F2170 (RH) or ASTM F1869 (calcium chloride) before install.
Pro tip: ASTM F2170 in-situ RH is the gold standard test, but the number you want is lower than most installers think. Manufacturers commonly cap at 80-90% RH, but slabs hovering at 85% can still cause long-term gasket and adhesive issues. If your slab tests above 80% RH, slow down and investigate the source before scheduling install — high readings rarely fix themselves.
Moisture barrier (concrete subfloors):
Below/on-grade concrete: install 6-mil polyethylene moisture barrier with 6-8″ sealed-tape lap joints.
Pro tip: We recommend 6-mil polyethylene vapor barrier over every concrete subfloor regardless of test results. Seasonal moisture shifts, future plumbing leaks, and unseen slab cracks mean a clean moisture test today doesn’t guarantee a dry subfloor in five years. 6-mil poly is $30-50 for a whole room — inexpensive protection. Overlap seams by 6-8 inches, seal with waterproof tape, run 2-4 inches up the walls (hidden by baseboard). This is industry-standard per NWFA and what we’d do in our own home.
Underlayment (do not replace the attached pad)
IXPE/EVA acoustic pad pre-attached — do not add underlayment beneath floor.
Pro tip: Customers sometimes ask about adding a thicker pad under Insignia 20MIL for more softness. Don’t. Insignia 20MIL ships with a 1mm IXPE acoustic pad already factory-attached to the WPC core — this is the only approved underlayment, and adding any second pad creates an unstable stack-up that causes click-lock seam failure over time. The warranty specifically voids structural-integrity coverage if a non-manufacturer pad is used.
Installation method:
Floating click-lock per Unilin Angle-Angle method. Maintain 3/8″ expansion gap at all walls and transitions.
Pro tip: For rooms wider than 25 feet or longer than 40 feet continuous, add a T-molding expansion break. WPC is dimensionally stable but not dimensionally inert — large rooms need room to breathe. Ignore this on thicker WPC at your peril; the extra thickness makes seam pressure more pronounced when expansion has nowhere to go.
Radiant heat compatibility:
Hydronic radiant systems compatible up to 85°F (29°C) surface. Increase temperature gradually after install.
Pro tip: Turn the heating system on at least two weeks before installation to purge slab moisture. After installation, raise temperature in 5°F increments per day back to operating level. Never go from room-temp to full heat in one day — thermal shock can compromise the click-lock edges and 1mm IXPE acoustic pad adhesion.
Daily maintenance:
Sweep or vacuum daily. Damp-mop with vinyl cleaner.
Pro tip: Use a cleaner specifically labeled for luxury vinyl or WPC — Bona Pro Series Luxury Vinyl Floor Cleaner works well. Avoid ‘mop and shine’ products that leave a film; they trap dirt and dull the RTS Scratch-Resistant Coating finish over time.
What to avoid:
Avoid abrasive cleaners, bleach, ammonia, wax, oil-soaps. Do not drag furniture. Avoid latex/rubber-backed mats.
Pro tip: Steam mops are the #1 warranty-void cause on Paradigm floors — Paradigm’s master warranty explicitly denies coverage for any damage caused by steam cleaners, and the moisture/heat breaks down the adhesives in the plank construction. Customers sometimes say ‘but it’s waterproof’ — the core is waterproof; the seams and adhesives are not designed for pressurized hot water.
Furniture and pet protection:
Use felt protectors under furniture legs. Wide non-marking casters for rolling chairs. Walk-off mats at exterior doors.
Pro tip: Office chairs with plastic wheels are harder on WPC than pet claws. Paradigm’s warranty specifically excludes damage from caster wheels unless they’re wide rubber — swap plastic wheels for rubber or silicone, or use a chair mat. This is in the written warranty, not a suggestion.
Frequently asked questions
How do I estimate how much flooring I need?
Pro tip: Don’t shortchange the 10% buffer. If you end up with 3-5 extra cartons, keep them — don’t return them. Even if you reorder the same SKU in 3 months, it’ll be a different manufacturing batch with slightly different tone and grain. It won’t match your existing floor. The extras are insurance against leaks, furniture damage, or cracks down the road.
Can I install WPC myself?
Most common case: DIY is allowed, but install mistakes (missed expansion gap, bad subfloor prep, wrong stagger, skipped moisture barrier) void that portion of coverage. Material defects from the manufacturer remain covered.
A few brands go further — their warranty requires “professional installation by a licensed contractor” as a coverage condition, so any DIY = warranty void even without mistakes. Check your brand’s warranty language before deciding.
Pro tip: when a claim is filed, the manufacturer sends a licensed flooring inspector. DIY that followed manufacturer spec to the letter passes inspection; DIY that cut corners won’t. We recommend: price out a licensed contractor quote first, read your warranty carefully, and decide based on your comfort with the procedure — not just labor savings.
Will it work in my basement?
Layer 1 — concrete moisture epoxy applied directly to the slab (manufacturer-approved liquid-applied membrane). Allows ~25 lbs/1000sqft/24hr vapor transmission vs the 8 lbs/1000sqft/24hr ASTM F1869 requires.
Layer 2 — 6-mil polyethylene sheeting on the cured epoxy. The epoxy resists normal slab conditions; the plastic above is insurance against slab cracks from settling or seismic movement (common in older Bay Area homes built on fill). If the slab cracks in year 12, the plastic stops moisture before it reaches your WPC.
Cost: $600-1,100 for a typical basement vs $50-100 for plastic alone. For a floor lasting 20+ years in a moisture-prone slab, double protection pays for itself the first time the slab shifts.
How does WPC compare to real hardwood?
Real hardwood investment = engineered with 3mm+ veneer. That’s the threshold where the floor becomes refinishable (2-3 refinishes over 50+ years, updated stain colors as trends shift). Appraisers factor genuine hardwood into home value; they don’t factor WPC.
Caveat: engineered hardwood with 1-2mm veneer (common in budget lines) is functionally the same as WPC — can’t be refinished, lasts 20-25 years. If you’re paying hardwood prices, verify the veneer spec. We carry both categories — happy to walk through specifics based on your rooms and refinishing expectations.
Do you offer samples I can take home?
How fast does it ship?
What’s your return policy?
Always covered at no cost: manufacturing defects, wrong product shipped, delivery damage documented on receipt. Call (408) 753-3220 to report.
Why not returnable by default: reverse freight on a pallet runs $300–800 with damage risk through 6 handoffs — Kapriz carries that exposure.
Rare written exceptions: 25% restocking fee + customer pays freight. Never for opened cartons, custom orders, or discontinued runs.
Pro tip: call (408) 753-3220 to arrange a sample loan before a large order — confirm the color is in the showroom (inventory rotates).
What does it look like installed in a real room?
Our website shows a fraction of our showroom inventory. We carry 80+ flooring brands in person, including samples not yet listed online. Bring Pinterest references, designer drawings, or specific brand/color targets to our Santa Clara showroom — we’ll cross-check against current availability and supplier catalogs. Many designers come with clients to browse the full collection and pull cabinet + tile + flooring samples side-by-side. Don’t see what you need? Text photo to (408) 753-3220 or stop by.
Will it match my cabinets?
Where it gets harder: very dark espresso cabinets can compress visual contrast — consider a lighter floor for those. Bring a cabinet door sample to our Santa Clara showroom; we’ll pull St. Lawrence for direct side-by-side comparison.
Best way to confirm a match: bring your cabinet door or paint card to our Santa Clara showroom — we’ll compare it against St. Lawrence under real lighting. Don’t have cabinets yet? We carry Boxy Cabinetry on-site (framed, frameless, regular shaker, slim shaker, flat panel — 11 finishes from Ivory White to Black Walnut) — use Boxy door samples to dial in your cabinet + flooring combination in one showroom visit.
What does the plank look like up close?
Sample tip: the difference between $2/sqft printed-vinyl and St. Lawrence only shows at close inspection. Hold samples side-by-side in daylight at 12 inches.
Will it look this bright in a windowless basement?
Windowless spaces: the multi tone reads slightly cooler under artificial-only lighting. Hex stays same; perception shifts.
Best test: grab a 24×24 sample from our showroom for an hour-long basement test.
Is this floor suited for plant-heavy interiors?
One concern: direct sun under south-window fiddle-leaf can fade some WPC tones over years. UV-filtering film worth pairing for maximalist plant + sun setups.
