Abstract

This report summarizes the findings of MEWS Task Group 3 on the Properties of the following building materials.

1. Oriented Strand Board 2. Plywood 3. Brick 4. Mortar 5. Stucco 6. Wood fibreboard 7. Composite wood siding 8. Water resistive barrier 9. Exterior grade gypsum board 10. EIFS base and finish coats and 11. Spray polyurethane foam

The properties that have been experimentally determined include:

1. Thermal conductivity of the dry material as a function of temperature 2. Water vapour permeability/permeance as a function of relative humidity 3. Equilibrium moisture content as a function of relative humidity/suction 4. Moisture diffusivity as function of moisture content 5. Water absorption coefficient 6. Air permeability/permeance

For the first eight materials, several products were tested to establish the range of properties shown by each material available in North American market. The main purpose of this investigation was to provide representative material properties as inputs for IRC's hygrothermal model hygIRC.
