1. What Are Vitrified Tiles vs Porcelain Tiles? (Technical Definitions)
Vitrified Tiles – Overview
- Base: Clay mixed with other minerals, fired to achieve a vitreous, dense body.
- Water absorption: Typically 0.5–1.0%, classified as vitreous.
- Use case: Popular as ceramic floor tiles in residential and light commercial projects.
- Look & finishes: Available in matte finish tiles, glossy, lappato, carving, sugar, soft-grip, etc.
- Export positioning: Ideal for buyers seeking a balance of cost, durability, and aesthetics.
Porcelain Tiles – Overview
- Base: More refined kaolin clay, feldspar, quartz and carefully controlled mineral mix.
- Water absorption: ≤0.5%, classified as impervious porcelain tiles.
- Use case: Outdoor porcelain tiles, freeze-thaw resistant tiles, heavy-traffic commercial floor tiles.
- Strength: Higher density and MOHS hardness 7–8, excellent scratch resistance.
- Export positioning: Premium product for high-performance, low water absorption tiles in demanding climates.
Where Ceramic Tiles Fit In
- Standard ceramic tiles:
- Water absorption 3–7% (semi-vitreous) or >7% (non-vitreous wall tiles).
- Best used as indoor wall tiles, low-traffic floors.
- For export buyers: Ceramic floor tiles are still relevant but porcelain and vitrified tiles dominate where technical performance and long-term durability matter.
2. Technical Comparison: Composition, Manufacturing, Water Absorption, PEI, Slip Ratings, Hardness
2.1 Composition & Manufacturing Process
Common manufacturing stages for vitrified and porcelain tiles:
- Raw material preparation (ball mill grinding)
- Spray drying to obtain fine, uniform powder
- Hydraulic pressing to form tiles (higher pressure for porcelain tiles)
- Drying to remove moisture
- Glazing (matte, glossy, lappato, satin, carving, sugar, anti-slip coatings)
- High-temperature roller kiln firing
- Porcelain tiles: ~1200°C+
- Vitrified tiles: ~1030°C
- Standard ceramic tiles: ~1050–1100°C
- Sorting, grading, quality control, packaging and palletization
Key takeaway for buyers:
Porcelain tiles use more refined raw materials and higher firing temperatures, giving higher density, lower water absorption and better technical strength compared to standard vitrified or ceramic floor tiles. When evaluating vitrified tiles vs porcelain tiles, water absorption and slip ratings are the most critical parameters
2.2 Water Absorption, PEI Rating, MOHS Hardness & Slip Resistance
Technical Comparison Table
| Parameter | Porcelain Tiles | Vitrified Tiles | Ceramic Tiles |
|---|---|---|---|
| Water Absorption (ISO 10545-3) | ≤ 0.5% (impervious) | 0.5–1.0% (vitreous) | 3–7% (semi-vitreous), >7% (wall) |
| Classification | BIa GL (porcelain) | Vitreous floor tiles | Semi-/non-vitreous |
| PEI (Glazed) | Typically PEI 3–5 | PEI 3–4 (depending on glaze) | PEI 2–3 mostly |
| MOHS Hardness | 7–8 (very scratch-resistant) | ~6–7 | 5–6 |
| Typical Slip Ratings | R9–R13 / P1–P5 (finish dependent) | R9–R11 / P1–P4 | R9–R10 (limited higher ratings) |
| Freeze-Thaw Resistance | Excellent (suitable for outdoors) | Good in many climates, check data | Poor to moderate |
PEI Rating (Porcelain Enamel Institute)
- PEI 0: Walls only, no foot traffic.
- PEI 1–2: Very light traffic (guest bathrooms).
- PEI 3: Moderate traffic (kitchens, living rooms).
- PEI 4: Heavy residential, light commercial.
- PEI 5: Very heavy commercial traffic (airports, malls, hospitals).
For export buyers, focus on PEI 4–5 tiles for commercial floor tiles and high-traffic projects.
MOHS Hardness
- Porcelain tiles at 7–8 MOHS resist scratching from sand and grit better than most natural stones.
- This is critical for outdoor porcelain tiles, large format tiles in lobbies, and commercial floor tiles where rolling loads and frequent cleaning are expected.
2.3 Slip Resistance – DIN 51130, AS 4586, DIN 51097
DIN 51130 (R-Ratings, shod feet)
- R9: 6–10° – dry indoor spaces (low slip risk)
- R10: 10–19° – kitchens, entrances, occasional wet areas
- R11: 19–27° – frequently wet, commercial kitchens, laundries
- R12: 27–35° – food industries, pool surrounds
- R13: >35° – industrial, very high contamination risk
Architects often evaluate vitrified tiles vs porcelain tiles based on slip resistance ratings like R10, R11 or R12.
AS 4586 (Pendulum test, P-Ratings)
- P0–P2: Low slip resistance (not ideal for wet floors)
- P3–P4: Moderate to high slip resistance
- P5: Very high slip resistance (recommended for outdoor wet areas)
DIN 51097 (Barefoot areas)
- A: Light slip risk (dry/barefoot zones)
- B: Pools, domestic showers
- C: Commercial pools, spa & gym showers, jacuzzis
For R11 slip resistant tiles or R13 non-slip tile for pools, porcelain tiles with textured, carving, sugar or soft-grip finishes are usually the best fit.
3. Thickness, Rectification, Warpage & Shade Variation (How to Avoid Complaints)
3.1 Tile Thickness Options
- Ultra-thin tiles (3–6 mm): Wall cladding, low-load areas.
- Standard wall tiles (6–8 mm): Kitchens, bathrooms.
- Residential floors (8–10 mm): Bedrooms, low-traffic floors.
- General floors (10–12 mm): Living rooms, standard commercial.
- Heavy-traffic floors (15–20 mm): Malls, stations, outdoor patios.
- Outdoor/driveway tiles (20+ mm): High load capacity, weather resistance.
For exporters and buyers, thickness directly affects:
- Breaking strength & modulus of rupture
- Weight per box and per container
- Container capacity optimisation
3.2 Rectification & Dimensional Accuracy (ISO 10545-2, ANSI A137.1)
Key tolerances you should demand in a ceramic tile specification sheet or porcelain tile technical data:
- Dimensional tolerance: ±1.0% up to max ±2 mm (standard), ±2.0% (commercial).
- Straightness of sides: ±0.5–0.6% of tile size.
- Rectangularity: ±1.0% deviation from true 90°.
- Surface flatness (center curvature): ±0.5–1.5% of diagonal.
Rectified tiles (precisely cut edges) allow:
- Narrow grout joints
- High-end modern look
- Better alignment for large format tiles (600×600, 600×1200, 800×800)
But they also magnify substrate and warpage issues, so QC is critical. In most international markets, the choice between vitrified tiles vs porcelain tiles depends on climate and durability needs.
3.3 Warpage / Bowing Limits
- ISO 13006: Maximum ±0.5% of tile edge length.
- Example: For a 600 mm tile, max allowable bow is ~3 mm.
- ANSI A137.1: Similar limits, with stricter rules for large format tiles.
- For 24″ (≈610 mm) tiles, warpage tolerance can be ~0.75% (~4.5 mm), but best-in-class manufacturers stay much lower.
Buyer tip:
In specifications and pre-shipment inspection checklists for warpage-free flat tiles, insist on:
- Warpage test results as per ISO 10545-2
- On-site lippage and flatness tests during installation
- Substrate flatness within ±1/8″ in 10 feet
3.4 Shade Variation (V1–V4 Scale)
- V1 – Uniform: Almost no variation (solid colour).
- V2 – Slight: Some variation, overall consistent.
- V3 – Moderate: Noticeable variation across pieces, more “natural stone” feel.
- V4 – Substantial: Very high variation, each tile may look unique.
When marketing digital printed tiles, carving tiles, or textured floor tiles, always clearly communicate the V-rating to avoid surprises for the end customer. The biggest difference in vitrified tiles vs porcelain tiles comes from their water absorption and firing temperature.

11. FAQ: Vitrified Tiles vs Porcelain Tiles – Technical Buyer Questions
Q1. What is the difference between porcelain and ceramic tiles?
Porcelain tiles use more refined raw materials, are fired at higher temperatures (around 1200°C+), and have water absorption ≤0.5%, making them denser and more durable. Standard ceramic tiles have higher water absorption and are best suited to walls and low-traffic floors.
Q2. Are vitrified tiles better than ceramic floor tiles?
Yes, for floors and export projects, vitrified tiles usually outperform basic ceramic floor tiles:
- Lower water absorption (0.5–1.0% vs 3–7%+).
- Better abrasion resistance (higher PEI).
- More consistent performance for residential and light commercial floors.
Q3. When should importers choose porcelain tiles over vitrified tiles?
Choose porcelain tiles when:
- You need freeze-thaw resistant tiles for cold climates.
- You supply outdoor porcelain tiles or non-slip tile R13 for pools.
- You target heavy commercial projects where PEI 4–5, high MOHS hardness and robust performance are critical.
Q4. How is water absorption measured in tiles?
Water absorption is measured according to ISO 10545-3:
- Tiles are dried, weighed, immersed and reweighed.
- The percentage increase in weight due to absorbed water determines the water absorption class.
Q5. What is PEI rating and why does it matter?
The PEI rating measures glaze surface abrasion resistance. Higher PEI ratings (4–5) indicate a tile can withstand heavier foot traffic, making it suitable for commercial floor tiles.
Q6. What causes tile warpage?
Tile warpage can result from:
- Uneven shrinkage during firing.
- Inconsistent raw material mix.
- Excessive tile size with insufficient firing control.
That’s why buyers must check warpage measurement standards, lippage calculation and tolerance, and insist on rectified tiles from stable production lines.
Q7. Why are large format tiles harder to install?
Large format tiles (e.g. 600×600 porcelain tiles, 800×800 ceramic tiles, slabs) magnify:
- Substrate unevenness.
- Warpage and lippage.
Installers must follow large format tile installation guidelines and use suitable levelling systems and expansion joints.
Q8. What is lappato finish compared to glossy?
- Lappato tiles: Semi-polished, a balance between matte and glossy, with soft reflections and better practical slip resistance.
- Glossy tiles: High-shine, reflective surfaces, great for walls and dry areas but more slippery when wet.
Q9. Which tiles are best for commercial kitchens?
- Anti-slip ceramic tiles for commercial kitchens or porcelain tiles with:
- R11–R13, P4–P5 slip ratings
- Chemical resistant tiles, stain resistant tiles
- PEI 4–5, high MOHS hardness. Understanding vitrified tiles vs porcelain tiles is essential when comparing water absorption and PEI ratings
Q10. How should tiles be packaged for export?
Key points:
- ISPM-15 certified pallets.
- Boxes with internal cushioning and corner guards.
- Moisture barrier wrap.
- Clear labelling with batch, shade, size and weight.
- Careful container loading requirements tiles to avoid overloading and damage.
