Hi again Folks,
   I have a patio door by Therma-Tru that is about 4 years old now, and I had 
to replace the double glazed window twice now because the seal had somehow 
broken and the glass gets vapor and condensation between the two paines.  The 
first time the local distributor replaced it free, the last time this Jan I 
had to pick up the window and install it myself.  I have been told that I 
should expect this problem when these insulated windows receive direct 
sunlight, the cycles of heating and cooling will break the seal.  My neighbor 
has had the same problem with his Peachtree patio doors.  Has anyone else had 
this problem or knows a solution?  Seems like I will have a problem every 
other year and the warranty will be over soon.  Again, any help is 
apprecaited!
   Thanks!
   Take care, Joe
