March 2018 Educational Seminar and Meeting

Ventilation is used to manage moisture and temperature in attics and crawlspaces, yet most ventilation is undersized and poorly incorporated.  As many as 4 different trades must coordinate on a new home to properly ventilate the attic.  A lack of coordination results in most attics being poorly ventilated.   While attics and crawlspaces are physically connected to a home, the air, moisture and pollutants in these spaces should not be exchanged with the rest of the home.  The attic and crawlspace ventilation must be separate from the ventilation that provides fresh air to the living space.

Topic Two "Air Leakage: The 3rd Most Destructive Home Issue"

Air Leakage: The 3rd Most Destructive Home Issue

Keeping homes dry and warm is essential for an effective controlled environment.  Controlling air flow has been overlooked as a key aspect of achieving these goals.  Air flow affects indoor air quality, comfort, building durability, condensation, combustion safety, recurring mold, icicles and more.  We will explore these and other issues and show how uncontrolled air flow can be the common link among many problems in homes. Air sealing solutions will also be presented. While "homes have to breathe", we will discuss what that means in a practical sense rather than it being a justification for sloppy installations and poor assemblies.
