How to Keep Dangerous Garage Fumes Out of the House
Should I supply make-up air to my house, or perhaps a well-sealed door between the house and the garage, to keep noxious fumes out?
That’s the question Jack Woolfe poses in a post at GreenBuildingAdvisor’s Q&A forum.
Starting or parking a car in the garage produces carbon monoxide. And the garage is often the place where we store gasoline and other fuels, paint, adhesives and a variety of materials that produce noxious fumes. Woolfe has more than a passing concern because he plans to build an airtight house.
To provide fresh air indoors, Woolfe is planning to install an exhaust-only fan. Will that draw fumes from the garage into the house? Or are their construction techniques that will guarantee indoor air stays healthy?
That’s the subject of this week’s Q&A Spotlight.
