Insulation - The Endura Flap consists of a sealed unit that is slightly thicker than a dual-pane glass unit and provides comparable insulation qualities.

Heat Transfer Barriers - Heat transfer across an air space in a sealed unit is caused by air currents moving within the space. These currents are caused by the continuous heating and cooling of the air inside the unit. The Endura Flap is divided by horizontal barriers which serve to reduce the effect of these air currents.
Adjustable Magnets On Both Edges and at Threshold

Wind Resistance and Training
The worst performance a pet door can have is when it blows open in the wind. Then it's really leaking a lot of air!
The Endura flap pet door has been proven in a wind tunnel to resist blowing open in winds in excess of 50 mph! In the same comparison testing, two of the largest selling pet doors on the market blew open at approximately 20 mph. (One was in the high 'teens', the other in the low 20's).
Nearly all customers have been satisfied with Endura flap wind resistance "out of the box". However, magnet kits are available to further increase wind resistance. Each size will accept up to two additional magnet pairs across the bottom of the flap which increases the magnet strength in that area by 50% to 300% depending upon the size of the flap.
Some users would like the flap to be easier to push open while training. The Endura flap design allows for temporary elimination of magnets on the sides as well as across the bottom.
When these magnets are removed, the Endura flap is extremely easy to push and the floating threshold remains in the low position.
