Our contribution

Part 1

ISOVER products release a very low amount of Volatile Organic Compounds (VOCs) and can meet the highest requirements for WELL certification. In several countries, ISOVER products are certified by independent institutes such as Greenguard (USA), Blue Angel (Germany), RTS M1 (Finland) or the mandatory product labeling in France. For example, the majority of our French products are rated at A+, which means that the level of VOC is less than 1000 μg/m³.

The innovation process of Saint-Gobain ISOVER is permanently targeting lower VOC emissions or products with materials that are free from formaldehyde.

Our glass wool products show a low amount of formaldehyde and can meet the WELL certification requirement. To learn more about the specific value, please refer to your local team.
