How does home ventilation work?
When hot, humid air meets a cold surface or area, the air will condense and form water droplets. If hot, humid air cannot properly circulate out of your home, condensation will build up in your attic, on your ceilings, or in your roof, causing major damage.
A ventilation system allows your home to breathe and cycle out old, dirty, moisture-filled air for new, fresh air through the use of intake vents and exhaust vents, which work in conjunction with one another. Insulation is another important component to a properly functioning as it helps to keep conditioned air in the living space of a home.
