Ventilation
When we talk about ventilation, we actually are talking about two different things: interior ventilation and structural ventilation.
Proper interior ventilation is vital to the health and comfort of your family. It helps your home rid itself of moisture, smoke, cooking odors, and indoor pollutants. Structural ventilation controls heat levels in the attic, moderates dampness in the crawlspace and basement, and keeps moisture out of uninsulated walls.
