    Abstract

    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.
