Essential - General - Why Are The Flaps Different Between Sizes?

Modified on Thu, 8 May at 2:59 PM

The Small and Medium Essential Pet Doors feature a flexible clear PVC flap, while the Large size uses a rigid polycarbonate (PC) flap.

This difference in flap material is due to several practical reasons:

Durability for Larger Pets
Bigger dogs exert more force when passing through the door. A flexible flap may tear or wear out more quickly, while a rigid flap can better withstand frequent use and impact.
Improved Weather Resistance
Large flaps cover a bigger area, so a solid flap helps seal the opening more effectively. This reduces drafts, keeps rain or snow out, and helps maintain indoor temperature.
Structural Stability
Flexible materials can sag or warp at larger sizes, which affects performance. A solid flap keeps its shape and continues to close properly over time.
Better Usability for Big Pets
Rigid flaps swing more consistently and don’t get stuck as easily. For larger pets, this makes using the door smoother and less awkward.
