I use Alu extrusion that is used on commercial windows, got it twenty years 
 ago, but they may still use it.  Bert

My  experiences placing my thunderbolt board in various insulated 
containers show  little or no improvement over simply putting a cardboard box over it 
to keep  drafts away.   As time allows I'm going to re run some of the 
tests  using my 5370 and an external standard vs relying on the data from the  
thunderbolt itself but I'm not expecting to see any significant  changes.

I've also started to run some tests with disciplining turned  off on the 
thunderbolt and the drift of the ocxo is quite  apparent.

I'll likely get a heavy die cast box for my thunderbolt at  some point.
