Products with a perm rating of 0.1 and lower are considered vapor barriers. Products with a perm rating greater than 0.1 and less than 1.0 are considered vapor retarders. Products with a perm rating greater than 1.0 are called "breathable." Consider ambient conditions and operating temperatures when selecting a mastic. Consider using water-based mastics for environmental reasons.
