Slab vapor barrier sill sealing question
What’s the best way to integrate sub slab vapor barrier into the exterior air barrier?
I’m getting ready to flash openings and install my WRB on my house this weekend.
-Prosoco Joint& Seam Filler and Prosoco Fast Flash for seams and window openings.
-6mm Sub Slab Vapor Barrier, left long under sill sealer.
Should I cut fold down the vapor barrier, bridge the sill plate with a butyl tape, then lap over that with the VP100?
Use Joint and seam filler along the sill plate, cutting the vapor barrier short, then lap over that with the VP100?
Fold vapor barrier UP and cover it with VP100?
I’ve found a number of different detail drawings, but am not sure of the downsides to different methods.
