To Vent or Not to Vent

Spray Foam

Danny and Joe welcome callers’ questions each week on the Today’s Homeowner Radio Show.

Here’s a question from our April 11 broadcast:

Edward wants to know if he needs both open vents in the ceiling and a return filter in the attic.  He just recently bought a 6-year-old home with a sealed attic and spray foam insulation.

The biggest advantage to applying spray foam insulation to the rafters in your attic is that you’ll be creating a more energy-efficient envelope around your home, which means you’ll be spending a lot less energy and dollars on heating and cooling.

Any gable, soffit, louver, or power vents in the attic will need to be removed or sealed shut.  This is because the entire attic will be turned into a conditioned space.

Ventilation like a range or bathroom fans do still need to be pushed through to the outside.
