TL;DR: In this paper, the critical moisture levels for ten building materials with a range of expected critical humidity levels (wood-based materials, gypsum boards and inorganic boards) were evaluated.

TL;DR: Viitanen et al. as mentioned in this paper proposed a dose-response model by which onset of mould growth can be predicted for an arbitrary climate history of combined relative humidity phi and temperature T. The model is applied to predict time to onset of mold growth under natural outdoor climate (under shelter) as well as mould development in building attics and in crawl space foundations.

TL;DR: In this paper, a laboratory study was conducted to investigate the effect of changing humidity and temperature on the growth of mould in a building, and the results showed that when the period of unfavourable/favourable conditions was longer (1 week), growth was affected more than if the duration of these conditions was short (12h).

TL;DR: In this article, the authors used accelerated laboratory tests, at constant temperatures and relative humidity (RH) favorable to mould growth, to determine a critical moisture level for mould growth. But, the results serve well to indicate mould growth within a building construction.

TL;DR: In this paper, an innovative laboratory test method for determining the critical moisture level (RH crit) of a material is described and discussed, and the results from testing a material according to the method gives information to make the correct choices.
