Insulation tape

904 Views 6 Replies 4 Participants Last post by  Gary in WA
I have paper faced insulation in the attic that has some tears in the paper. I'm going to replace the sections that are real bad, but in the areas that just have small tears, I want to tape it up. Is there a proper type of tape for this?

The insulation is directly under the roof decking. House is a colonial built in '43 with a walk up attic.
As far as I can tell, there is no air gap between the insulation and the roof. The only rigid air barrier that has ever been there is a some thin luan paneling. Probably been in place since the early seventies. The attic is unvented save two small windows at each end.

I understand the concerns, but the existing insulation has worked for 73 years with no mold or moisture issues. All I'm looking to do is restore the integrity of what's there. That said, I'm not opposed to doing more, but I'd need more convincing since I have a functioning system with no evidence of a problem anywhere.
