Permeability of materials wufi 6.6

Post by Michael Hurd » Thu Feb 02, 2023 10:06 am -1100

I've noticed that the old perm/in line item has disappeared in WUFI 6.6 and now has "water vapor diffusion resistance factor" in its place - is there a calculation that we can use to convert a manufacturer's perm ratings to this new resistance factor? I read the help article on this and do not understand the path to converting manufacturer's perm ratings to this new factor.

Never mind, my bad, I forgot to make inch-pounds my default when I upgraded to 6.6 :oops:
