I have a plastic spacer that uses PET polyethylene Phthalate in its al foil section . However , I don't have the conductivity of the PET and its not in the NFRC data base. What can I do when running U simulations?

Hi, if you know who the manufacture and product name of the spacer bar, it might be listed in the BF Two Box method list:

Guide to:

Scroll down to find:

There is also a list for façade profiles too.

Hop this helps,

Phil.
