Migration of water by capillarity / by Armand Patenaude. : NH15-177/1997E-PDF

"The main objective of this research project is to predict capillary ascension in a crack or tube for various construction materials present in building envelopes. Secondary objectives involve the determination of: angle of contact of the water with the material, maximum height between two horizontal surfaces which allows the adhesion of rain water between them, and the maximum height which water can attain on a horizontal surface. The experimental analysis of the parameters defined above was conducted for over 30 base materials and for 6 hybrid systems. Certain recommendations as the design of windows and other exterior siding components are also developed"--Summary.
