Does anyone tape the joints of kraft faced insulation? I was told that to maintain the vapor barrier all of the joints should be taped. Is this true.

Rd: I don't think that many of the folks who use krat faced bats care about maintaining a continuous vapor barrier. Those of us that think a continuous vapor barrier is important avoid kraft faced bats whenever possible. Chase
*Thanks for the info. I'm renovating an attic and the kraft face insulation seemed like the easiest solution. I guess not.
*RD. Will you have useable space in the atic or are you ust insulating the attic floor? Youi best bet if the latter is blown in cellulose. GeneL.
*How do you guys install FG kraft-faced insulation? I always attach it to the face of the studs, but this FH article installing fg says you should staple to the side of the studs. I remember reading that stapling to the sides starts an airflow in the resulting air gap, which lowers r-value. Any thoughts on this?jim
*I will have usable space. I'm creating two bedrooms and a bathroom. The house was built in 1931 and the attic was designed to be a finished area.
*IMHO: If you have to use kraft faced bats ... applied to the face of the stud offers a much tighter job. The reason folks around here staple it to the side is to make it easy for the dry wall hangers to find the studs.
*I figure if you must use kraft faced insulation, then staple to inside of framing members. Can you say loose drywall?If you desire a vapor barrier then use 6 mil poly.joe d
