Insulated Pet Doors for Hot and Cold Climates!
In any pet door, the biggest heat and cooling loss is in the flap itself. The Security Boss Insulated pet doors address the heat and cooling loss in the flap using multiple methods. First of all, the pet flap itself is a high quality vinyl that hangs well and won't shrink up in the cold weather. Next is the seal of the flap itself. The Security Boss Insulated pet doors use alnico magnets. These magnets are stronger and ensure the flap seals correctly every time. Then, there is the pile material that lines the flap again ensuring a great seal on the flap each time your cat or dog uses the insulated pet door. The final factor is the dual flap system. There is one flap on the inside and one on the outside creating an air gap between the flaps. This works similarly to your dual pane windows where the air gap itself creates a barrier of insulation between the flaps. Finally, if weather is really bad and you do not want to have your pets using the insulated pet door anyway, there is an insulated slide-in blocking panel for an additional layer of insulation when the pet door is not in use.
