Terrace: the standards of flooring

UPEC classification

The UPEC classification lists floor coverings according to their resistance to repeated aggression.
Each letter is followed by an index ranging from 1 to 4. The higher the number, the better the material:

UWear due to walking and abrasion
PPunching due to furniture
EWater resistance
CResistance to chemical agents

Standard ABC

The ABC standard indicates the resistance to slipperiness of a mineral coating barefoot.

ATAverage adhesion (slippery)
BHigh adhesion
CStrong adhesion

Only slabs marked B or C can be placed near a swimming pool.
Class C slabs may be placed in water.

Classes of wood

This ranking determines the level of resistance of wood to moisture.

1 and 2Wood for interior use
3, 4 and 5Wood for outdoor use

The structure of the wood reacts to the climatic conditions. A wood intended for a terrace (or an outside path) must be located at least at level 4 of the classification.
