Hello. We have been using the Heat and Moisture Transfer (HAMT) objects in E+ for an ongoing project. However, only spruce and plywood are currently available in the E+ dataset. Can anyone share HAMT examples for more wood species? Thank you.

Hamt is based on WUFI. The WUFI program has a library of materials that contain a number of wood and wood-based products. You can make your own E+ property file from the library data. I'm not sure how many of those materials are included in the free versions of WUFI, but you could look there if you don't have access to a Pro version of WUFI.

Hi, I took air layer properties from Wufi database, but it seems it is causing me lot of errors because of the very low sorption isotherm values, any idea how to model air layers in HAMT?

Thanks very much. I've found a rich dataset of moisture property data there.
