The Patio Pacific Endura Thermo Panel 3E Pet Door with the Endura Flap is a single pane sliding door pet door, that uses low 'E' glass.

This design is perfect for areas with extreme weather because helps retain heat in a house in a freezing blizzard, or keep the cold air in during a heat wave. The single pane, low 'E' glass minimizes and sometimes eliminates condensation on the glass.

In addition, the Thermo Panel 3E features the award winning Endura Flap Pet Door, the only pet door design that has won the Dog Fancy and Cat Fancy Publication's Editors' Choice Award for Creativity and Innovation. 

This Thermo Panel IIIe model - is identical to the Quick Panel III.  Both are dog doors for sliding glass doors, but the other Quick Panel model uses a single pane glass, which is less effective for extreme climates.

• Easy Installation - Does not require tools or a drill to install.  It features an easy to use and unique user adjustable step-over to adjust to the pet door opening to any height that your pet might need.
• Built-in Room for Measurement Errors (aka "Anti Whoops" Feature) - In the event your measurements are slightly off, you have the chance to save the situation by using the "anti-whoops" feature, allowing for 3/4" change in adjustment range.
• Keeps Your Home Safe and Secure - The Thermo-Panel IIIe includes an easy way to lock any sliding door as well as a secure metal frame and a robust locking pet flap cover.  The sturdy locking cover comes with every Endura Flap pet door, and has been designed to have a strength equivalent to 1/16" steel plate.
• Safe for Your Pets - The patented flexible nature of the Endura flap is safer than other pet door with a rigid door designs, because it removes any of the flap pinching or snagging on your dog or cat, in the event they pull back quickly while walking through the door (this can happen if he/she gets scared while walking through)
• Strong Insulation - The Endura flap combines single-pane glass, which offers superior insulation for greater energy efficiency.  You will save money on energy bills.
• Built to Last - The cost of replacing the flaps on most cheap pet doors often exceeds the original cost of the door. Most pet door flaps begins to split, wear, and eventually break after repeated use.  The Endura flap uses a unique pivoting design, to avoid wear and breakage.
• Environmentally Friendly - The Endura Flap is made using non-toxic, recyclable, and green for the environment a polyolefin-based polymer (similar to material used in food storage containers).  Most other pet doors are made with PVC, or vinyl, which is very harmful to the environment.
