Get a Healthier Home with Proper Ventilation


Ventura Hidden Vent


Families breathe easier when fresh, clean airflow circulates in and around the home.


Did you know that people spend on average 90% of their days inside? Between home, office, shopping and the car, we’re inside more than we think. According to the US Environmental Protection Agency, indoor air can be up to 2 to 5 times more polluted than outside air due to off-gassing from interior finishes like paint, carpet and flooring and from activities such as cleaning, cooking and bathing.

Humidity from cooking and bathing can result in mold, mildew and other allergens that adversely affect people with asthma and allergies. Proper home ventilation helps prevent moisture buildup and contributes to a healthier living environment. While mechanical features such as updated kitchen exhaust fans can enhance ventilation, there’s a lot going on behind the scenes to ensure natural ventilation creates a healthier building envelope.


Roofs, Walls and Soffits are Used to Create Ventilation

Due to increasing energy efficiency standards, many homes are tightly sealed to prevent air leakage, but several parts of the home have natural ventilation built in from the start.

Roofs – Most roofs are designed with vents in them to create natural airflow through vented soffits in the lower parts of the roof and escape through roof ridge or gable vents. This keeps the attic cooler and prevents moisture from building up inside it.

Walls – Homes are designed to include utility vents in walls to promote airflow that removes moisture and prevents the buildup of polluted air inside.

Soffits – The horizontal space between the roof’s eaves and the wall, soffits allow for passive ventilation up into the roof.

Vents or vented materials on walls and roofs work together to take advantage of passive ventilation. That means hot air rises and escapes through vents high in the roof, while cooler air flows in through vented soffits and wall vents.
