Vapor retarders on insulation batts
There are a lot of different kinds of insulation batts sold.
Some have kraft face, others are fully encased in plastic, and some are without any facing on either side.
Most batt jobs I see done by insulation companies are of the bare variety.
All the ones sold at my local lumber yard are either plastic encased or have the kraft paper.
Can someone explain when/where you’d use all these various types of batts.
