Are there any entry doors that are made in north america that are suitable in a Passive House?  Would adding a storm door help?  I kinda cringe at the idea of importing doors from europe.

We just put in Thermatru fiberglass doors in our new build.  I'm pretty sure they have u-values, infiltration, etc., on their website.  From all accounts, they are one of the more efficient doors you can buy, and are not horribly expensive.  We did a craftsman style front entry door with side lights and a transom, & it was about $1500..

this is the door we installed..

edit - I found the u-value info.  The door is .24
