Explication of the pictograms
To be able to project a clear view of all our products, we use worldwide standardized icons. The user now is able to simply recognize the special properties of all the individual subfloor systems. A clear explanation of the icons we use on our site, is to be found on this page.

There are 7 fire Classes: A1, A2, B, C, D, E en F. When referred to flooring, the class is recognisable when it is followed by the indication “fl” (floor) in subscript: for exampel: Bfl . A1 is the highest class which indicates these products will not contribute in any form to a fire. Products with hardly any contribution to fire will be classed A2. When a material is not tested or does not meet the requirements of E Class, automatically it will be classed as Ffl. |
