Question: Which way should vapor barrier face?
Mark writes from New Bedford, Massachusetts: "I have garage under house the floor is insulated face to heat with vapor barrier. I intend to insulate garage ceiling creating 10 inch space under this insulation I will sheet rock. Which way should vapor barrier face? Garage is not heated and 10 inch space will have plenty of ventilation from heated basement."
Answer: If there is already faced insulation under the floor of the living space, I would not recommend using faced insulation but rather unfaced insulation instead.
