Measuring effect of Activ’Air

As part of a school renovation project in Kallo, Belgium, Gyptone conducted tests of two almost identical rooms to document the effect of Activ'Air. Gyptone ceilings were installed without Activ'Air in one room, but with Activ'Air in the other.

Activ'Air was shown to have a lasting effect: one tile from each room was removed three months after installation for testing in a laboratory. The results showed that Gyptone Activ'Air continued to help reduce the formaldehyde concentration.
