Our contribution

Part 1

Conforming to ISO 16000, GYPROC products have low ammonia, formaldehyde and other VOC emission levels close to 0. With our A+ ranking according to French VOC regulations and conformity to high international standards in construction products, GYPROC product VOC levels fall far below the maximum standards set by WELL. See the table below for Total VOC and Formaldehydes.

For example, VOC levels are reduced by 70% when using our Activ’Air® /AirRenew® solutions.
