What material in the database can you use to model the following??
1. Standing seam metal roof
2. Steel metal roof deck

1. Standing seam metal roof
none, I would create a metal layer
2. Steel metal roof deck
available in the Pro 6.1 database
3. Glass Mat Gyp Coverboard
There are a generic gypsum and a gypsum product available in 6.1 Pro database. I would use one them and adjust thickness and perm value according to spec.

Hi tmartincps,
the metal roof/ roof deck I would take in account by just setting an sd-value in the boundary condition and switching off the rain at the same time. The calculation will be much faster that way.
Effective sd-values would be 25-50m for the standing seams and 300m if the seams are sealed. You also could assume there are no seams, which could be expressed by an sd-value of 1500m.
For the coverboard I would use a gypsum board, which should be rather similar.

PS: Did not see, that Manfred already answered. But it is better to use no diffusion tight layer directly on the surface in WUFI 2D. Use the sd-value instead.
