Which side of the basement ceiling insulation goes up–faced or non-faced?
Faced insulation should be placed with the facing toward the heated part of the home. Exposed (unfaced) insulation should be covered with an interior panel or finish if the area is going to be occupied or used frequently. Install basement ceiling insulation with the facing on top, and cover the ceiling if the basement is going to be used frequently.Source:energy.ca.gov; Procedures for proper installation of insulation.
