I received the pet door very quickly and in perfect condition.  I had it unpacked and installed in less than an hour and it works exactly as advertised!  I am very pleased with myself for deciding to spend the extra money and get a patio pet door and not only does everything it says it does, but matches my dual pane slider so well that it looks like it was made for it.  And it does insulate as advertised.  I live in Phoenix and it is already over 100 degrees here.  My AC is set for 72 degrees (I am not a native desert dweller - I am originally from Washington State so I am more comfortable keeping my home a little cooler than most people do) and the room in which the pet door is stays at the same 72 degrees as the rest of my house.  Now that's a perfect example of how insulating the Thermal Panel III is!  Oh, and let's not forget the Edura Flap, it also works as promised.  The Endura Flap so superior to the typical vinyl pet door flap that it is ridiculous to even try and compare the two!

Thank you so much for providing such an exceptional product!    Regards,  Cherrie S.

 p.s. please feel free to use me as a testimonial and/or a reference (It is extremely rare for me to be so satisfied and happy with a product that I purchased that I would go so far as to write the company about it!)

The Endura Flap Pet Door for Sliding Glass Doors -
The Original Thermo Panel III Patio Pet Door - was a major upgrade to the very successful Thermo Panel II. The difference was that the Thermo Panel III used the new award winning "Endura" flap--the best pet door flap ever made--while the Thermo Panel II used flaps and framing made by other manufacturers. The benefits of the Endura Flap are far more important than whether the glass is single pane or dual pane.

Now introducing the Thermo Panel IIIe -
All of the features of the Thermo Panel III with the addition of "Low E" glass for the insulated glass units. Low E glass consists of a special coating on the inside of the unit which greatly improves the energy efficiency of the insulated glass unit.

There are quite a few details that might be important for you to think about in purchasing any panel pet door. Begin with 'Key Points' to get a quick overview of the most important issues. Then study the 'Comparison Chart' and read the information on the Patio Panel FAQ page which cover the fine points of patio pet doors. 

Hot Tip: People almost always visually over-estimate the width of the flap needed by their dog. To avoid this problem, call the dog through a doorway opened only enough for him to comfortably pass. Then measure the gap. 

Then measure the height of the dog at the withers (top of the shoulder).  Inspect the chart to the right to ensure that your pet is no taller than the maximum height value available for that model. If your pet is taller than the maximum or if you need a shorter rise (for another, smaller pet for example) go up to a larger size.

1 'Rise' is the height of the flap above the base of the pet door. We suggest that 'flap height' + 'rise' should about equal pet shoulder height. Unlike any other panel pet door on the market, the Thermo Panel IIIe can be adjusted by the user to the rise dimensions shown in 2" increments. Here's more info on the 'Adjustable Rise'. Custom orders cannot be resold. Therefore, they must be a final sale once built. Note that the insulated glass units for custom height orders take three to four weeks for delivery from the tempering plant and that we need about 1-2 weeks to schedule the assembly after the glass unit arrives.
