Describes the development of a new method for measuring water vapour transport through common building materials. States the method represents an improvement in accuracy and flexibility over the standard ASTM (American Society of Testing and Materials) cup methods. Also supplies preliminary test results using gypsum wallboard materials.KEYWORDS: Materials, measuring, testing, water vapour, accuracy, flexibility, gypsum plasterboard
