To achieve better indoor air quality, products designed for use in buildings and indoor spaces have to meet strict chemical emission limits, which contribute to the creation of healthier interiors. The aim of the voluntary emission classification is to enhance the development and use of low emitting building materials.
Emission Classification is product-specific.
All materials have emissions at some level – even pure nature materials have emissions. Building materials and interior decorations emits various chemicals into indoor air. The Emission Classification of Building Materials presents the emission requirements for the used materials with respect to good indoor air quality. The M1 class stands for low emissions.
The M1 classification is used only in Finland. The Building Information Foundation RTS maintains and publishes a directory of currently classified products and the holders of right of use on its website.
Voluntary labelling system
“The emission classification of building materials is a voluntary labelling system open to all manufacturers, importers and exporters of building products. The classification does not overrule official building codes or interpretations of them. However, many developers, architects and designing engineers favour M1 classified products when selecting materials for their projects. The Finnish Association of Building Owners and Construction Clients (RAKLI), the Finnish Association of Architects (SAFA), and the Finnish Association of Consulting Firms (SKOL) recommend to their members the classification system in order to promote high-quality construction.“
