While the Durisol material is inert with no VOCs
or off-gasing, the cement content of the Durisol
material creates an above average pH
environment at the wall surface , that inhibits the
growth of fungi and mold. Furthermore, the
hygroscopic nature of the material moderates
relative humidity levels (65% RH maximum) and
provides an inherent moisture regulator that keeps humidity low and further serves to repress any
type of fungal growth.
