Floor boxes and data sheets often show codes such as AC4 or class 32. These ratings help you choose a floor that will last in a home, an office or a shop. This guide explains what they mean in simple terms.
Key points
- AC ratings (AC1 to AC5) describe the abrasion resistance of laminate floors.
- Use classes describe where a floor can be used: 2x for homes, 3x for commercial spaces, 4x for light industrial.
- For homes, AC3 or class 23 is usually enough. For offices and shops, look for AC4 or class 32 and above.
- Always check the rating on the product specification, not only on marketing material.
AC ratings for laminate
The AC rating comes from the European laminate standard EN 13329. It shows how well the surface resists abrasion and wear.
| AC rating | Typical use |
|---|---|
| AC1 | Light domestic use, such as bedrooms |
| AC2 | General domestic use |
| AC3 | Heavy domestic and light commercial use |
| AC4 | General commercial use, such as offices and boutiques |
| AC5 | Heavy commercial use, such as busy public areas |
Use classes
Use classes come from EN ISO 10874. The first number shows the area type, and the second shows the traffic level.
| Class | Area | Traffic |
|---|---|---|
| 21 | Domestic | Light |
| 22 | Domestic | General |
| 23 | Domestic | Heavy |
| 31 | Commercial | Light |
| 32 | Commercial | General |
| 33 | Commercial | Heavy |
| 34 | Commercial | Very heavy |
| 41 to 43 | Light industrial | Light to heavy |
How to choose
| Project | Suggested minimum |
|---|---|
| Bedrooms and living rooms | AC3 / class 23 |
| Busy family homes | AC4 / class 23 or 31 |
| Offices and hotel rooms | AC4 / class 32 |
| Shops and busy corridors | AC5 / class 33 |
What about SPC and vinyl?
SPC and vinyl floors are not rated with the laminate AC scale. Their durability depends mainly on the wear layer thickness. They are classified with use classes in the same way. A thicker wear layer suits commercial use.
Tips for buyers
- Ask for the rating in writing for each design you order.
- Match the rating to the busiest part of the project.
- Remember that sand, chair legs and pets wear floors faster. Use mats and felt pads.
Frequently asked questions
Is AC4 better than AC3?
AC4 has higher abrasion resistance and suits commercial spaces. AC3 is usually enough for homes.
Does a higher AC rating mean the floor is waterproof?
No. The AC rating is about surface wear, not water resistance.
What rating do your floors have?
It depends on the collection. We confirm the rating and wear layer for each product in your quotation.
