"W" (not that W) writes from Cleveland, Ohio: "I am remodeling a addition to our home and have 3 outside walls with Kraft faced R-11 31/2" insulation in the walls, ripped out old paneling and drywall. I also want to use Film-Gard Polyethylene Sheeting Product #B0408 as an extra vapor/air/moisture barrier. Can I do this without any problems down the road? I also have some tears in the insulation; what can I do for those? Duct tape?"

Answer: The only way you can use two vapor barriers within one assembly is if the vapor barriers are in direct contact with each other.

Yes, you can repair small tears in Kraft paper with duct tape.
