Ventilation

It is important to consider ventilation when creating an energy efficient, airtight home.  Proper ventilation allows you to control the flow of air so you don't seal in indoor air pollutants.

Ventilation works along with air sealing to give you an energy efficient home that is still able to exchange indoor air with outdoor air.

Ventilation also helps control moisture, another important consideration for a healthy, energy-efficient home.

Purpose of Ventilation

Your home needs ventilation to exchange indoor air with outdoor air.  Proper ventilation will help reduce indoor pollutants, moisture, and odors.

Contaminants such as formaldehyde, radon, etc. can accumulate in poorly ventilated homes, causing health problems.

Excess moisture in a home can generate high humidity levels, leading to mold growth.

There are many common vents, such as ridge vent or box vents, that will properly ventilate your home with controlled air flow.
