Everything concerning the adequate application of WUFI in the USA and Canada depending on local conditions e.g. architecture, building codes, standardization, laws et cetera.

What are the correct values to enter into the Material Database for the popular "Zip Wall" product.
Is it similar to the material that is distributed named "Fibreboard Plain High"?

Hi Roger,
One way would be to use a regular OSB board from the database and add a 1mm thick membrane to it, the 1 perm vapor retarder from the database would work. Then you need to adjust the perm-inch value (or mue value in case you are a metric guy) of the membrane to reflect the correct vapor permeance of the air barrier. Get the data sheet from Huber to do so.

The other option is contact Huber and they provide you with data.

When you say add a 1mm thick vapor barrier, you mean to draw a rectangle on the outside of the OSB? In other words, membranes should be modeled with thickness instead of a boundary condition between 2 materials?
When I import a .dxf with <mm membranes drawn, they don't graphically show in WUFI 2D. I can assign a material to the polygon in the Materials dialog though.
