Is a single flap enough for severe winter weather?

A single flap Endura Flap pet door is extremely energy-efficient and capable of withstanding winds up to 50 mph. Because of its secure magnetic seal, it will insulate your home more than the average single flap door.

If you commit to a single flap door, you can increase the insulation value by increasing the magnetic strength.

Why is there a difference in pet door flap size for the single versus the double flap models?

Since each flap is dual walled, they are much thicker than average pet door flaps (about 7/8" thick). This means that when the pet puses through a double flap door, the inner and outer flap can stack on top of each other and take up more space. This means that there is a loss of about 1" at the top of the entryway. It's vital for your pet's long term health that they have enough clearance to walk through the pet door without scraping their backs; to help customers find the best fitting flap more easily, we calculate the loss of space into our flap size recommendations.
