The moisture performance of framed structures—A mathematical model

Abstract A mathematical model is developed for the moisture performance of a framed structure (e.g., a flat roof or a wall), containing a hygroscopic framing material and a cavity filled with air or insulation. A formula is developed that connects the enclosed and unenclosed drying time constants for the framing material. The enclosed drying time constant alone describes the longer term moisture behaviour of the structure (much greater than one day) under any driving forces given the linearity assumptions used. The model allows for anisotropic framing materials with initial moisture contents above or below fibre saturation.
