Why Spray Foam Insulation Impacts Ventilation Needs

Spray foam insulation goes from a liquid to a solid, allowing it to make excellent contact with your walls, blocking air flow. Since spray foam inhibits natural airflow to an extent, you will need to readjust your home’s ventilation in order to accommodate this. Without updating your ventilation, you may begin to experience some undesirable side effects, including stale air, trapped moisture in insulated rooms and indoor air pollution.

Understanding the Basics of Home Ventilation

Home ventilation consists of different elements that contribute to airflow throughout your house. There is natural ventilation, spot ventilation and whole house ventilation. 

  • Natural Ventilation: An example of this would be opening a window to allow fresh air into a space.
  • Spot Ventilation: This involves a dedicated ventilation component for a specific area in your home. For example, having an exhaust fan in your washroom. 
  • Whole House Ventilation: This is simply the combination of vents in your home that draw in air from outside to facilitate fresh airflow. 

Finding ways to increase each of these three types of ventilation will help support your newly insulated home. 

Ventilation Strategies for Spray Foam-Insulated Homes

  • Add Exhaust Fans: Adding spot ventilation in the form of exhaust fans in your kitchen and washrooms can help ensure that these areas have constant airflow when in use. Just ensure that you install one that is sufficient in size.
  • Utilize Windows: Regularly opening your windows can help stale air exit your home and fresh air enter. If possible, you can even look into adding additional windows throughout your home. 
  • Install Mechanical Ventilation Systems: Install a whole-house ventilation system in order to eliminate stale air and excess moisture.
