The BF-Bulletin 004 ‘Guide to warm edge for windows and facades’ is a good introduction to the topic of warm edge. It is a manual for the often used BF-data sheets with representative Psi-values for windows and for facade profiles and explains the boundary conditions for the use of the BF-data sheets according to ift-guideline WA-08 (windows) and WA-22 (facades).

By the request of many, the bulletin was translated into English and French language.

You can find both versions on the literature page of my website, or you can directly download the English paper here and the French one here.
