Low-emission materials and furniture

The criteria for M1-certified building material was developed and published for the first time over 20 years ago in 1996. M1-classification sets limit values for the emission of VOC, formaldehyde, ammonia also the acceptability of the odour associated with the material is assessed.

M1-label on the product tells that the product complies with the M1-criteria for emission and odour. The aim of the classification is to enhance the development and use of low-emission building materials and furniture.

M1-classification is product and company specific

The Building Information Foundation maintains and publishes a freely accessible database. All products with valid M1-certificate can be found in the database using the search function.

Companies which have been granted the right of use of the M1 label may use it for marketing purposes. The classification label shall not be used in marketing in such a way that it refers to the company as a whole or to products which have not been granted M1 classification.

Voluntary labeling system

The emission classification of building materials is a voluntary labeling system open to all manufacturers, importers and exporters of building products. Many developers, architects and designing engineers favour M1-certified 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 their members the M1-classification system in order to promote high-quality construction.

The M1 certification body is the Building Information Foundation RTS sr

The Building Information Foundation RTS sr is Finland’s leading information service for the building and construction sector. Its mission is to foster and promote good architect and engineering practices in the building sector as well as sound property management procedures. The Foundation is a private institution with representatives from 54 Finnish building organisations.

Classification work is developed and supervised by the Committee Indoor Air Classification (PT 17) appointed by the Director General of the Building Information Foundation RTS sr. M1-applications and matters relating to classification decisions are examined by a separate technical classification working group elected by the Committee. The application form and all the product related information provided by the applicant are kept confidential.

The Classification of Indoor Environment 2018

The emission classification of building materials is part of the Classification of Indoor Environment 2018, which is used in the design and construction of healthier and more comfortable buildings and their mechanical systems.

The first version of the emission classification was developed by the Finnish Society of Indoor Air Quality and Climate (FiSIAQ) in 1995 as part of Classification of Indoor Climate, Construction, and Finishing Materials.
