5mm SPC Click
Flooring Manufacturer
4mm Rigid Core + 1mm IXPE
The engineering case for 5mm is straightforward: above 4mm core thickness, dimensional stability reaches the same ≤0.10% threshold regardless of additional core depth. Consequently, specifying 6mm or 7mm for a hotel guest room or apartment does not improve performance — it only increases logistics cost per m². We recommend 5mm for every project where the subfloor is flat to ≤2mm/2m and the utilisation class does not exceed Class 33.
Achieved at 4mm.
Not Improved Beyond It.
What the Numbers Mean for Your 5mm Project.
Every SPC manufacturer publishes the same parameter list. The difference is whether those numbers are explained in the context of real installation conditions. Consequently, each parameter below is described in terms of what it means for a US multi-family building, a UK hotel renovation, or an Australian retail fit-out — the three environments where 5mm SPC is most commonly specified.
| Parameter | Value | Standard & Market Context |
|---|---|---|
| Total Thickness | 5mm (4+1) | 4mm SPC rigid core + 1mm IXPE pre-attached. No separate underlay required. |
| Core Density | 1.95–2.05 g/cm³ | Limestone-PVC composite. Same density target as 6mm and 7mm — stability is compound-dependent, not thickness-dependent. |
| Dimensional Stability | ≤ 0.10% | EN ISO 23999 · ASTM F2199 — stable across US radiant heating range 15–28°C and Australian summer-winter delta. |
| Impact Sound | △IIC 21 dB | ASTM E2179 — pre-attached 1mm IXPE. Contributes to US IIC ≥50 assembly requirement in multi-family construction. |
| Peel Resistance | ≥ 50N / 50mm | ISO 24345:2006 — co-extrusion bond, not adhesive. No delamination risk over product lifetime. |
| Residual Indentation | avg. 0.05mm | ISO 24343-1 — below visual detection threshold at standing-height inspection distance. |
| Fire Rating | Bfl-S1 / ASTM E648 CI | EN 13501-1 for EU/UK · ASTM E648 Class I for US. Both available — specify destination market on inquiry. |
| Slip Resistance | R10 / DS | DIN 51130 · EN 13893 — dual-certified for wet and dry zone commercial applications. |
| Wear Layer Options | 0.3 / 0.5 / 0.7mm | EN 660-2 Group T all three options. 0.5mm most specified for US hotel and UK residential. |
| Click System | Uniclic / Välinge 5G | Both systems available. Uniclic for standard floating install; Välinge 5G push-down for faster renovation. |
| GREENGUARD Gold | TVOC ≤ 0.22 mg/m³ | UL 2818 — qualifies for LEED v4 IEQ credit 4.3. Required for US school and healthcare SPC specifications. |
| FloorScore | SCS-FS-05154 | CDPH Section 01350 — required for California market and LEED-certified US commercial projects. |
| FOB Price Range | US$6.35–7.00/m² | 0.3mm from $6.35 · 0.5mm from $6.60 · 0.7mm from $7.00 — FOB Shanghai or Ningbo. MOQ 800 sqm/SKU. |
Correct specification for multi-family residential, rental apartments, and guest rooms with low foot traffic. At 0.3mm, the wear layer provides 10–15 years of residential lifecycle under normal use. Specifying 0.5mm in these environments does not extend the lifecycle — it increases cost without a performance return.
The volume standard for US hotel guest rooms, UK commercial renovation, and Australian light commercial fit-outs. At 0.5mm, the wear layer achieves Class 31/33 utilisation and a 15–20 year commercial lifecycle under normal hotel and office foot traffic. Furthermore, 0.5mm is the minimum wear layer required for most US hotel brand specifications and UK commercial building warranties.
Heavy commercial specification on 5mm core. Correct for retail, healthcare corridors, and educational environments where Class 42 utilisation is required but the project budget does not accommodate 6mm or 7mm SPC. Specifically, 0.7mm wear layer on 5mm core is the US specification for commercial spaces where ASTM F1700 Type III Grade 1 compliance is required.
The global standard for SPC floating floor installation. Uniclic-compatible joints engage with a fold-down motion — the long side of each plank clicks into the previous row at a shallow angle, then lowers flat. Consequently, no mallet is required on the long side, and the joint achieves the lock strength needed for Class 33 commercial utilisation without tools. Available on all 5mm SPC configurations.
The Välinge 5G system uses a patented plastic locking strip on the short end — the plank pushes straight down to engage both long and short side joints simultaneously, without the rotation step required by standard Uniclic. Specifically, installation speed is approximately 30–40% faster than Uniclic on the short side, making 5G the preferred system for US hotel room renovation where the project timeline is measured in hours per room.
12 Trending Decors. All Available in 5mm SPC.
All 12 colours below are produced from the same décor film library as our 6mm, 7mm, and 8mm SPC. Consequently, a project specifying 5mm in guest rooms and 7mm in corridors can use the same colour code throughout — and we produce both thicknesses from the same print run for guaranteed colour consistency. This is our Universal Colour Matching guarantee across all SPC thickness specifications.
Hotel & Hospitality · Class 31/33
5mm SPC with 0.5mm wear layer is the standard hotel guest room specification across US, UK, and Australian hotel brands. The 5mm total profile installs within standard door clearances without frame modification — a critical constraint in hotel renovation projects where rooms must return to service within 24–48 hours. Furthermore, the Välinge 5G push-down click system reduces installation time by 30–40% versus Uniclic on the short side, supporting tighter renovation schedules.
Multi-Family Residential · US Market
5mm SPC is the dominant specification for US multi-family residential new build and renovation — driven by three factors: it meets IIC requirements with pre-attached IXPE without a separate underlay, it fits within standard apartment door clearances, and it delivers the lowest FOB cost per m² in the click SPC category. Consequently, US multi-family developers and property management companies specify 5mm as the default SPC grade for market-rate and affordable housing projects.
Light Commercial · Office & Retail
For light commercial environments — boutique retail, open-plan offices, and educational spaces with Class 31/33 utilisation — 5mm SPC with 0.7mm wear layer delivers the performance of a heavier specification at the 5mm price point. Specifically, the 0.7mm wear layer achieves Class 33/42 utilisation on the 4mm core, making 5mm a viable commercial specification for spaces that do not require the sustained wheeled-load performance of a bonded Dryback installation.
Which SPC Thickness Is Right for Your Project?
SPC thickness is an engineering decision, not a quality decision. The correct thickness is determined by three factors: the EN 685 utilisation class required, the subfloor flatness available, and the logistics budget per m². Specifically, 5mm is not a compromise — it is the engineering optimum for the majority of residential and light commercial projects. The following comparison explains when to stay with 5mm and when to upgrade.
The volume standard for hotel guest rooms, multi-family residential, and light commercial across the US, UK, and Australia. At 1.95–2.05 g/cm³, the 4mm core achieves the same ≤0.10% dimensional stability as heavier SPC — at the lowest FOB cost and lightest container weight in the click SPC range.
The correct upgrade when subfloor flatness exceeds ≤2mm/2m — the additional 1mm core depth increases the plank’s bridging capacity over minor subfloor irregularities. Furthermore, 6mm is specified for projects where door clearance permits the extra thickness and budget allows the modest FOB premium.
The EU heavy commercial standard. The 6mm core delivers enhanced bridging over subfloor irregularities and greater resistance to sustained point loads — relevant for retail shelving, medical equipment, and hospitality trolleys in Class 42/43 commercial environments. Additionally, 7mm is the default SPC specification for EU social housing in Germany and the Netherlands.
The maximum click SPC specification. The 7mm core delivers the highest bridging capacity and point-load resistance in the click format. Consequently, 8mm is specified for the most demanding click SPC applications — large-format commercial, high-footfall retail, and Middle East hospitality projects where subfloor preparation budgets are limited and maximum performance is required without switching to bonded Dryback.
