SPC Flooring Buyer's Guide: 7 Quality Checks Before You Order
Seven checks to run before you order SPC flooring.
SPC Flooring Buyer's Guide: 7 Quality Checks Before You Order
Cheap SPC flooring fails early — it scratches, gaps and off-gasses within a year. Seven checks stop that happening.
The 7 Quality Checks
1. Total Thickness
SPC planks come in 4mm, 5mm, 6mm and 8mm. Thicker boards hide subfloor unevenness and resist flex. For US homes, 5mm or 6mm suits most rooms. Reserve 8mm for busy hallways and commercial jobs.
2. Wear Layer
The clear film on top decides how long the design survives. 0.3mm scratches quickly. 0.5mm handles family traffic and pets. 0.7mm is the commercial grade. Always confirm the figure in writing before you pay.
3. Click System
Our planks use 5G Click, licensed from Unilin. The joint snaps firmly and holds tight seams. Ask which lock the supplier uses and whether it is licensed. A vague answer here predicts gaps later.
4. Fire Rating
US building codes reference ASTM E84. Class A is the top band: flame spread index 0–25 and smoke development under 450. Request the test report. A listing without one is a warning, not a formality.
5. Emissions
E0 and E1 are the recognised formaldehyde limits. E0 is the stricter of the two. SPC cores contain little formaldehyde, but adhesives and print films can add some. Look for E0 or E1 results from an independent lab.
6. Certifications
Two marks matter. FSC confirms responsible forest sourcing for the print layers. CE marking to EN 14041 confirms the product meets European requirements for resilient flooring. Both should be verifiable by certificate number.
7. Surface and Warranty
Check the pattern range: wood grain, stone and marble designs should vary across boards, not repeat every three planks. Plank sizes like 1220×182mm or 1215×195mm suit most US rooms. Read the 1 year warranty terms before ordering.
Red Flags That Signal Low-Quality SPC
Too-Thin Wear Layer
If the supplier quotes 0.3mm for a living room or kitchen, walk away. That grade suits short-term or low-traffic use only. Homes need 0.5mm or more.
No Fire Rating Data
A product page that never mentions ASTM E84 usually has no test report. Without a Class A result, inspectors may reject the floor in commercial or multi-family projects.
Vague Certifications
Phrases like "eco certified" with no certificate number, issuer or standard mean nothing. Ask for the FSC and CE documents by number, then check them.
Missing Click System Details
If the lock type is unnamed, it is probably a generic profile with loose tolerances. Joints loosen, seams open and water finds its way down.
How US Homeowners Can Verify Before Ordering
Request Samples
Ask for two or three planks, not a small chip. Lay them out to see the pattern repeat and colour consistency.
Check the Documentation
Ask for the ASTM E84 report, the E0 or E1 emission results, and the FSC and CE certificates. Reputable suppliers send these within a day.
Test the Click Connection
Join two sample planks by hand. A good 5G Click joint snaps cleanly and holds when you lift one board. A joint that slides or clicks softly is a weak lock.
Inspect the Wear Layer
Scratch the sample edge with a coin. On a 0.5mm or 0.7mm wear layer, no clear film should peel or cloud. Any lifting film means the protection is thin or poorly bonded.
Good SPC vs Cheap SPC at a Glance
| Check | Good SPC | Cheap SPC |
|---|---|---|
| Total thickness | 5mm, 6mm or 8mm | 4mm only |
| Wear layer | 0.5mm or 0.7mm | 0.3mm or unstated |
| Click system | 5G Click, Unilin licensed | Generic, unnamed profile |
| Fire rating | ASTM E84 Class A report | No report supplied |
| Formaldehyde | E0 or E1 tested | No test data |
| Certifications | FSC and CE (EN 14041) with numbers | Logo walls with no numbers |
| Surface patterns | Wood grain, stone, marble, high variation | 2–3 patterns, obvious repeat |
| Plank sizes | 1220×182mm or 1215×195mm stated | Sizes change between quotes |
| Core cross-section | Dense, uniform, no air pockets | Chalky, streaked or crumbly |
| Sample policy | Full planks sent on request | Chips only, or samples refused |
| Warranty | 1 year written terms | Vague or verbal promises |
Summary
Seven checks stand between you and a failed SPC floor.
What to Do Next
Compare the full specification list on our SPC flooring range page. Contact our team with your room sizes and traffic needs, and we will send samples plus the matching test reports. Download the catalogue for the complete thickness, wear layer and pattern list.
Which wear layer do US homes need?
0.5mm for family traffic and pets. 0.7mm for rentals, shops and busy hallways. Avoid 0.3mm in any room used every day.
Why does ASTM E84 Class A matter in the United States?
It is the top band for flame spread and smoke development, and many codes reference it for multi-family and commercial spaces. Keep the report with your project files.
How do I confirm a supplier's claims are real?
Request full-plank samples, the ASTM E84 report, E0 or E1 emission results, and FSC and CE certificate numbers. Test the click joint by hand before you order.
