What Is M1 Certification?

Building materials for interior use, such as paints, can be classified according to the compounds they emit into the air. In Finland, the Sisäilmayhdistys association for good indoor air has published a building material classification that divides products into three classes (M1, M2, M3). The classification has also used in the other Nordic countries and in the Baltic countries.

The M1 class is for materials that emit extremely low levels of compounds into the room space, while materials belonging to the M3 class generate the highest amounts of emissions. Materials that have not been tested do not belong to any class. M1 certification is granted by the Finnish Building Information Foundation to products that have been examined by an accredited testing laboratory and have undergone an organoleptic assessment. Many of Tikkurila’s products are M1-certified.
