Splendid for Fairbanks Winters!

Hi, I purchased a door earlier this year based on the hope that it would hold up to the harsh Fairbanks winters. So far we have seen temperatures drop to -47 degrees Fahrenheit and there’s no draft! A little frost forms from my dogs going in and out, but it is just amazing! A severe wind storm took out some trees in our yard and blew open an attic hatch that was NAILED in, but the darn dog door didn’t budge. Thank you for making such a great product!
