Today we added our water resistant barrier (WRB) to the tiny house. WRBs with a score of 5 perms (short for permeance) are required by code. The plastic barrier we used scores anywhere between 5-50 and will prevent water entering the house, but will allow water to exit the house. This feature will help prevent water damage to the drywall, insulation, and wood frame.

After looking on lowes.com, the perm score of the wrap we used is 15.
