Anyone who works with insulating materials or lives in insulated buildings rightly asks themselves whether the material used is really harmless to health. With the SAGLAN glass wool from SAGER, the answer is clear and verifiable: Yes.

Whether during processing on the building site or during decades of use indoors, our SAGLAN glass wool fulfils the strictest international health requirements. Independent Certificates like RAL, EUCEB and the renowned Indoor Air Comfort Gold from Eurofins confirm the high level of health protection for processors and residents.

In this article, you will find out why our SAGLAN glass wool fibre technology is considered harmless to human health and how we ensure first-class indoor air quality in your projects.

Maximum safety during processing: fibres with rapid degradability

Respiratory protection is a key issue for tradespeople and installers. If particles are inhaled when cutting or installing SAGLAN glass wool, the so-called biopersistence is decisive. It describes how long a fibre remains in the body before it is biologically degraded.

Scientific analyses of the Fraunhofer Institute for Toxicology and Experimental Medicine (ITEM) confirm the high level of safety of our products. Study no. 02G07016 proved that our glass wool has a very low biopersistence. The half-life for the degradation of long fibres (> 20 µm) is only 11 days. This value is well below the legal limit of 40 days.

This means that SAGLAN glass wool fulfils the requirements of Note Q of European Regulation EC No. 1272/2008 and is officially classified as non-carcinogenic. Processors can rest assured that any fibres inhaled are quickly and effectively eliminated from the body.

This rapid biodegradability is a decisive advantage, especially in the professional construction environment. It ensures that SAGLAN glass wool does not remain permanently in the organism and therefore fulfils the highest health protection requirements. For planners, site managers and processors, this means additional safety in their daily work on the construction site.

Quality controlled by RAL and EUCEB

Safety is no coincidence, but the result of consistent quality controls. Our production at the Dürrenäsch plant is continuously monitored by neutral, external experts.

The RAL quality mark 388 regularly confirms that our mineral wool products are chemically composed in such a way that they remain harmless to health. The conformity of the SAGLAN line is officially confirmed twice a year by RAL GGM.

In addition, the EUCEB certificate (European Certification Board for Mineral Wool Products) guarantees that our products correspond to the tested reference fibre. This international certification gives architects, builders and processors the assurance that they are working with a material that meets the highest European health standards.

These continuous tests ensure that every SAGLAN glass wool produced fulfils the defined quality and health requirements. Transparency and comprehensible test reports create trust and enable a safe choice of material for new buildings and renovations.

First-class indoor air: certified by Eurofins Indoor Air Comfort Gold

Not only the fibres themselves, but also the emissions of volatile organic compounds play an important role in indoor air quality. That's why we at SAGER rely on maximum transparency through the Indoor Air Comfort Gold certificate from Eurofins with the certificate number IACG-332-01-01-2025.

This seal is regarded as the gold standard for product emissions in Europe. It confirms that our SAGLAN castors not only fulfil the legal requirements, but also meet the strictest voluntary quality seals such as the Blue Angel (DE-UZ 132), the French VOC class A+ and the German AgBB requirements.

Especially in living spaces, schools or office buildings, a low emission rate is crucial for the well-being of users. SAGLAN glass wool actively contributes to a healthy indoor climate and supports construction projects in which healthy living and sustainability are key criteria. For the occupants, this means a healthy indoor climate without harmful vapours.

Conclusion: Health and safety without compromise

The decision in favour of SAGLAN glass wool is a decision for uncompromising health. Thanks to the rapid biodegradability of the fibres and the extremely low VOC emissions, confirmed by Eurofins Indoor Air Comfort Gold, our products offer maximum safety during processing and a healthy living environment for subsequent use.

We guarantee you a product that has been scientifically tested and certified by leading European institutes.
