I’m getting close to the point where I need to turn the plywood sheathing of a double stud wall (which will be insulated with dense packed cellulose) into a proper air and water barrier. One approach I’m considering is to use Blueskin VP alone. Or should I consider taping the seams first?
Any concerns with using a vapour impermeable tape, such as 3M’s 8067? I’m somewhat restricted in the products I can use. Prosoco’s R-Guard system was my preferred approach, but didn’t get the green light from my building department.
