Realistic vapour permeability values
There is presently much discussion of the validity of conventional calculation techniques for predicting interstitial condensation. However, the success of any predictive method depends upon the accuracy of the vapour permeability values used as input data. Considerable information is available from standard tests, but the values quoted are generally unique to the conditions of the test and cannot be extrapolated to other conditions. An alternative approach is therefore suggested here, involving the concept of 'differential 'permeability, and a differential permeability curve is generated for exterior quality plywood.
