Air resistant - protects the wall assembly from air infiltration to increase the comfort of the building by reducing drafts and increasing energy efficiency. Allows trapped moistre to escape form wall to help promote drying in walls. Durability - has the ability to withstand the elements of the weather and tough jobsite conditions. UV Protected. Moisture vapor permeability - perserves the integrity of the wall assembly by allowing the moisture as vapor to escape to the outside..
