Sacie--I've seen Passive Houses specifying Therma-Tru doors lately.  I'm
not that confident they can compete with the euro's in terms of
air-tightness, so have been sticking with Intus...

WRT U-value, Intus offers glazing in their doors at U-0.11  This may not
compare with N American ratings--but Intus claims that their glazing
insulates more efficiently than their frames.  IOW's, it can pay to install
the largest glass area possible...
