SB: Warmer doors

[Derek Roff <derek@unm.edu>]

Strawbale wall- R-30+.  Door in strawbale wall- R-3?  I am thinking 
about the design of better insulated doors.  So far, I have concluded 
that they must be thicker, and as free from thermal bridges as 
possible.  Hinges and hardware look like a problem area.  Air seals 
are important, but seem tractable to me.  An airlock entryway is said 
to make a big difference, but the door in the wall still deserves 
improvement, in my opinion.

Has anyone else on the list worked on this problem?  I would like to 
hear other ideas, problems and solutions.
