High Tech Pet Products Armor Flex Low-E Patio Regular Height Pet Door
I had a Petsafe door for 4 years and this one is exponentially better for keeping out weather. It stays shut in even the highest winds. Very weather tight. Holding up to 3 large dogs slamming through it constantly. Only downside so far was the installation method. I would recommend getting rid of the factory lock tab and just screwing it to the frame in the same manner Petsafe is installed. Otherwise it will not seal well.
It’s cold when temperature drops. Top sliding piece has no insulation. Door frame itself seems to be hollow. It does stay shut in high wind but the plastic in the dog door becomes brittle and breaks over time. I glued the bottom flap on one fix but when the door broke at the top and the entire dog flap was outside, the door is done. Expensive, cold and doesn’t last
