Resistance to repeated aggressions, slipperiness, moisture, respect of the principles of sustainable development: System D helps you to see clearly in the different classifications of external flooring.
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:
|U||Wear due to walking and abrasion|
|P||Punching due to furniture|
|C||Resistance to chemical agents|
The ABC standard indicates the resistance to slipperiness of a mineral coating barefoot.
|AT||Average adhesion (slippery)|
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 2||Wood for interior use|
|3, 4 and 5||Wood 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.
Several labels certify the origin of wood that meets the principles of sustainable development.
|FSC||Forest Management Board|
|PEFC||Forest Certification Recognition Program|
|TFT||Organization for the forest|
|CTB-B +||FCBA quality label (technological institute)|
