Permeance- Meaning in Hindi - HinKhoj English Hindi Dictionary

WebWater vapor permeance, or “perms,” is the amount of allowable moisture migration within a concrete slab. The application of the concrete, as well as its mix, can determine permeability. For example, water vapor permeance is generally acceptable at less than 0.3 perms. However, a higher perm rate can be accepted in residential circumstances.
