Materials made from the renewable, sustainable, low-emission resource wood
Nobody likes polluted air, especially not indoors, where people spend 90 % of their time. That is why we are aware of the growing importance of indoor air quality: We check the emissions of VOCs (volatile organic compounds) of our products ourselves and also have them tested by independent institutes for their suitability for "healthy homes".
Everything you should know about emissions from wood-based materials can be found in our video.

Healthy homes with our products
The following products for furniture and interior design are certified according to the current award criteria of "TÜV PROFiCERT-product interior". This confirms that you are purchasing safe products that are suitable for "healthy homes". The certificate is monitored by an independent testing institute and the producing plants are regularly audited.
It means you are working with products that are both tested for harmful substances and comply with international emission requirements.
Examples of certificates:

What do wood-based materials emit?
Terpenes are natural ingredients that are mainly found in coniferous trees. They form the typical smell of wood - for example the scent of pine or Swiss stone pine.
Aldehydes are formed during the natural air drying of wood. The drying and hot pressing of our boards intensifies this process. The typical smell after mowing the lawn is an example of natural aldehydes (hexanal).
Organic acids are, for example, acetic and hexanoic acid. Acetic acid occurs in the hardwood and spruce wood used. It is a food preservative and is included in the WHO list of essential medicines.
The most common emissions from wood and wood-based materials are terpenes, aldehydes and organic acids. Depending on the type of wood and processing, these occur in different proportions and concentrations.
The health impact of this mix of substances has been scientifically studied: For example, a study by the WKI Braunschweig with the University of Freiburg found that even a multiple of the VOC (Volatile Organic Compounds) concentration measured in homes had no effect on health.*

Indoor air quality
Airtight construction methods are important measures for saving energy. The airtightness of the building ensures that heat, but also emissions, remain in rooms for longer.
Regardless of the construction method, a wide variety of factors influence the indoor air quality. Wood and wood-based materials are among the positively perceived influencing factors*. Ventilation conditions and user behavior subsequently determine the quality of indoor air. In all common rooms, other artificial emission sources also contribute to the indoor air quality in addition to natural ones. Therefore, the impact of interior fittings and related equipment should not be ignored.

Full transparency for our products
We make public all ingredients that are used in our products. There are two different document formats for this: Externally verified EPDs (Environmental Product Declarations), which make the life cycle assessment of our products transparent, and EHDs (Environmental and Health Datasheets).
