Questions

Is the Endura Flap pet door good for cold climates?

Yes. The Endura Flap uses a flexible polyolefin polymer flap and magnetic sealing design that helps reduce drafts and improve insulation. The flap remains flexible even in temperatures as low as −40°F.

How long do Endura Flaps typically last?

The lifespan depends on usage and weather exposure, but Endura Flaps are designed to last significantly longer than standard vinyl flaps. Many homeowners only need to replace them after years of heavy use.

Should I choose a single flap or a double flap?

A double flap traps a pocket of still air between the two panels, and that air gap is what does the insulating. If you have real winters, real summers, or a door that faces prevailing wind, the second flap is the difference you will actually feel.

A single flap is easier for a hesitant, small, elderly or recovering pet to push through, and it is the better choice in a mild climate or on an interior opening where insulation is not the point. If you are torn, consider which matters more day to day: the energy bill, or how confidently your pet uses the door.
