Smart Vapor Retarder

Post by holtzcjd » Fri Jul 21, 2017 3:50 am -1100

Has anyone modeled smart vapor retarders (like Certainteed MemBrain smart vapor retarder) in WUFI Pro? How does WUFI Pro handle these materials and how does the user input in materials that are smart vapor retarders? What information do we need to obtain from the manufacturer and how do we propperly set-up Wufi simulations?

thanks
david

Dear David,

for calculation the vapor resistance or permeability depending on the relative humidity of the material is needed.
This information can be entered in the hygrothermal functions of a material in the "water vapor resistance, moisture dependent". If given there, the smart vapor retarder is taken in account in the calculation automatically.
