Friendly materials


The healthiest building materials get a recognition medal: gold, silver or bronze.

The assessed products re-ceive an evaluation report with the summary of the analysis process.

Achieved medal

Three different medals may be obtained: gold, silver or bronze. In case the assessed product does not achieve a score high enough to receive a medal it will be given the word “rated”.


All the medals are valid for a one year period.


Each product will be included in it's corresponding category, enabling comparison with its peers. There are 9 main categories that subdivide into more specific categories. All the categories and sub-categories may be consulted at

How does the scoring system work?

The Friendly Materials’ medals are grouped by categories and each category has its own maximum score of FMPs.

The maximum score represents the highest number of points that a material from that category is able to achieve. Setting a maximum score for each category ensures the comparison of a building material with its peers, once there is no point in comparing paints with wood or ceramics with adhesives.
