Abstract
An ASHRAE Research Project (RP-1018) that has been concluded at the Institute for Research in Construction, the National Research Council of Canada, has resulted in a unique database on many hygrothermal properties of many common building and insulation materials that are currently used in North America. The properties that are determined include thermal conductivity, equilibrium moisture content, water vapor transmission characteristics, water absorption coefficient, moisture diffusivity and airflow characteristics. The experimental and analytical procedures used in the research project are all based on either International Standards or on well-documented and peer-reviewed approaches. The materials that have been investigated in the project include: several wood-based products, such as oriented strand board, plywood, wood fiberboard and composite wood siding; masonry products, such as clay brick, mortar and aerated concrete; five species of lumber; cladding products, such as stucco, fiber cement board and the exterior coatings of EIFS systems; seven insulation products; six sheathing membranes; interior gypsum board, primer and a latex paint; a natural stone, a cement-based sheathing board and vinyl wallpaper. This paper lists the basic information on all materials that are investigated. It also summarizes the principles of the experimental procedures. Illustrative examples of the information that have been generated in the research project are presented. Results from statistical analyses are highlighted.
