This property is de pendent on the local moisture content. The experiments that lead to the detailed in formation on the dependence of diffusivity on moisture content are often very so phisticated. However, two recent exercises, as a part of the activities of an International Energy Agency Annex, have shown that a correct estimate of the mag nitude of the moisture diffusivity can provide useful information with regard to its application in hygrothermal analysis. This technical note presents results from a sim ple moisture absorption measurement that led to a good estimate of the moisture diffusivity of building materials. Results from measurements on a sample of spruce are presented.","PeriodicalId":435154,"journal":{"name":"Journal of Thermal Envelope and Building Science","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127128878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The problems have included water penetration, damage to cladding systems and rotting and decay of wood components. The city of Vancouver, the National Standing Committee on Small Buildings and other industry groups have responded to the problem in various ways, and stakeholders have estabhshed the Building Envelope Research Consortium (BERC) to monitor this issue. The objective of this 1996 CMHC study was to examine the relationship between the building envelope problems and their potential causes. The findings would be used to help identify key aspects of the design, construction and operations and maintenance processes leading to the problems, and","PeriodicalId":435154,"journal":{"name":"Journal of Thermal Envelope and Building Science","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124609279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Asphalt-impregnated felt papers, spun-bonded polyethylene, perforated high-density polyethylene films, &dquo;water-resistant&dquo; sheathings, and red rosin felt papers all have their advocates. Unfortunately, building designers frequently specify some of these products that subsequently prove to be incapable of resisting water penetration. A few designers even insist that wood siding alone forms a weatherproof barrier and that you shouldn’t need to install building paper if you have a &dquo;good coat of paint.&dquo; Surface-sealed cladding systems eventually, if not initially, allow water to penetrate beyond the surface layer. Wood siding is no exception. Building paper for application beneath wood siding must be capable of retarding the migration of liquid water before it damages interior finishes and concealed wall components.
