When running ABS through an exterior wall for drain and vent, how does fiberglass insulation get put into place?
The existing R-13 Fiberglass insulation was installed 2 different ways. In some stud cavities, the ABS was in front of the fiberglass and paper vapor barrier that comes with it. In these cavities, the fiberglass was squished between the ABS and the exterior wall. Does that reduce effectiveness?
In other cavities, the vapor barrier had been peeled off of the fiberglass, and the ABS was between the fiberglass and paper barrier. In these cavities, the fiberglass was able to flow around the pipes. The paper barrier was stapled to the studs.
I have to replace a good amount of the insulation, so I'll have to choose which way, or some other way to do it.
Thanks.
