The moisture buffering capacities of five building materials which are widely used in North America was investigated experimentally. An experiment to quantify the moisture buffering capacity of building materials was developed. Hygrothermal properties of these building materials, reported in this paper, include the density, thermal conductivity, equilibrium moisture content, water vapor permeability, water absorption coefficient, and air permeability. Moisture buffering test results showed that among these materials the fiberboard product has the best moisture buffering capacity, whereas plywood has the lowest among the building products tested.Les capacit\ue9s tampon en mati\ue8re d'humidit\ue9 de cinq (5) mat\ue9riaux de construction largement utilis\ue9s en Am\ue9rique du Nord ont fait l'objet d'une v\ue9rification exp\ue9rimentale. On a ainsi mis au point une exp\ue9rience visant \ue0 quantifier cette capacit\ue9 tampon en mati\ue8re d'humidit\ue9 desmat\ue9riaux de construction. Les propri\ue9t\ue9s hygrothermiques de ces mat\ue9riaux, dont fait \ue9tat ce document, comprennent la densit\ue9, la conductivit\ue9 thermique, le degr\ue9 d'humidit\ue9 d'\ue9quilibre (\ue9quilibre hygrom\ue9trique), la perm\ue9abilit\ue9 \ue0 la vapeur d'eau, le coefficient d'absorption d'eau et la perm\ue9abilit\ue9 \ue0 l'air. Les r\ue9sultats des essais de la capacit\ue9 tampon en mati\ue8re d'humidit\ue9 ont r\ue9v\ue9l\ue9 que parmi ces mat\ue9riaux de construction test\ue9s, le panneau de fibres poss\ue9dait la meilleure capacit\ue9, et le contreplaqu\ue9, la moins bonne.Peer reviewed: YesNRC publication: Ye
