Just thinking about all the insulation questions and answers that say p/b is moisture -permeable, but then also thinking of all the things I have read that say plaster on walls doesn't breathe.
Can someone explain this for me ? The p/b is highly compressed, has two layers of paper covering and is permeable but plaster applied with the pressure of a float becomes impermeable ??
