Don't know if it saves energy from heating and cooling costs, but I would assume it does due to how well it seals and the thickness of the door. I also like it because you can see through it. Like any door, they will wear out, but I'll definitely buy another one when it does.

This door seals up better than ANY dog door I've ever owned...and I've had many! It's sturdy, the quality good. Can't say enough great things about it! A+++++

Simple installation the three piece design didn't pinch my puppies paws like one piece doors typically do when they are checking it out while teaching them to use the door.

Replaced an existing three-panel door that was falling apart....Like these because they really keep hot or cold air out and my dogs like the door. Excellent!
