Free Condensation in the Building Envelope webinar

Presented by Dow Building Solutions


The Mason Contractors Association of America (MCAA) will host Condensation in the Building Envelope on Monday, December 9, 2013, at 10:00 AM CST, presented by Dow Building Solutions.

A lot of ink has been spilled in describing the movement, condensation and evaporation of water vapor through a building envelope. Unfortunately all too much of it has been incomplete or even downright wrong.

In this presentation the physics of water vapor transport will be described in detail. Some sacred cows will be slain and fundamental concepts regarding more robust envelope designs will be described. The presentation will also take a look at the strengths and drawbacks of various calculation methods including the humble Dewpoint/Glaser method and the vaunted WUFI. Be ready to get re-acquainted with Dihydrogen Oxide on both the molecular and macroscopic scales.
