Insulated Glass Garage Doors

Has anyone used any of these before? I’m talking about the commercial-style (think service station bay) aluminum frame sectional doors with insulated glass panels and weathertight seals. I first thought about using them in a home breezeway (NY state) after I visited Burlington, VT, and saw a great number of restaurants were using them (whole side of the restaurant would open up to the outdoors in fair weather). They said they noticed no change in their energy bills before and after installation (but who knows what they had there in the first place…).
Any input? Any idea re: good manufacturers?

Garaga makes some very well insulated garage doors. They have several R-16 and an R-18 model. Even though the seals are very good, they're not going to be as tight against infiltration as, say, an Anderson or Peach Tree type of door, I believe. I'm happy with my Garaga door.

You could also email or write the restaurants in Burlington.
If you're considering a breezeway, don't forget to consider the room the door needs when it's open. Your breezway may need to be wide, or you might need some funky track design.
neighbor has this , looks like an EMS ambulance station
I'd love to have a glass garage door, but then people could see into my garage and I sure wouldn't want that.
