Is the Certainteed MemBrain smart vapor retarder listed in any of the material databases? I have looked but cannot find an entry that seems to match...
If not, how should it be represented?

Hello Steven,
the Certain Tedd Membrane is not listed in the database. The properties should be similar to the PA-Membrane from the Fraunhofer IBP-Source.
If needed adapt the values for the water vapour diffusion in accordance to the values from the producer. Doing that please don´t forget, that the values for membranes in the Wufi-DB are entered for a layer thickness of 1mm. So you probably have to convert the µ-value.

My understanding is that these are the same products. Originally developed in Europe, then brought to the USA.
