   Norman,
   Two brands usually rise to the top of the list:

   Endura Pet Door

   Freedom Pet Pass

   Norman,

   This is Don from Freedom Pet Pass. If you're frequenting Green Building Advisor, then our pet doors are likely for you. We're the only doors on the market that meet California's Title 24 building code, and we have third-party documented air leakage rate (0.03 cfm/sq ft, not a typo) and U-factor. If you're going to look at the Endura or any other brand of pet door out there, look very carefully at any "green" or "efficiency" claims - they're usually going to be very high on bluster and hand-waving, very low on data.

   Good luck with your search!

   Thanks, Donald.

   Martin, it looks like that Endura site has gone belly up. Here is another site for them.
