Summary 

Ventilation is extremely important to the well being of a structure. Air changes will reduce or eliminate moisture-laden air. Proper ventilation considers the natural high-low convection of warm and cool air.

 Condensation and ventilation rules: 

• Warm air has more ability to hold water than cold air.

• Moisture vapors only move from the warm side to the cold side.

• High-low ventilation takes advantage of the natural thermal convection of air.
