This innovative system doesn’t need to alter your existing sliding door frame. Instead, it replaces the glass panel with a pane of glass that has the doggy door built-in. The Patio Pet Door uses a unique mounting system, requires no special fasteners, and is custom built to the size of the existing glass unit. Your patio door will slide, function, and lock just like before. The sliding door dog door won’t interfere with secondary locks or existing alarm systems, and the pet opening itself is both easy to use and features a solid security panel.

Insulated Sliding Glass Dog Door with Advanced Components

Inexpensive pet door inserts have flooded the market. These contraptions, usually single-paned glass in an aluminum frame, wreak havoc on homeowner’s utility bills because they are designed to be cheap, not energy efficient. On the other hand, the sliding glass pet door from Advanced Window Products saves big in the long term thanks to the insulated safety glass, dual seal silicone, and highly energy efficient vinyl frames. Last but not least, it features a major upgrade on the most important part of any pet door: the pet flap.

The Endura Pet Flap, made from a specially designed polyolefin-based polymer, stands above all other pet flaps on the market.

  • Rigid pet doors may pinch or otherwise injure your pet, but our pet flap is soft and flexible.
  • This flap seals quickly and securely after your pet comes in, keeping poor weather and unwanted wild animals outside where they belong.
  • Magnetic strips line the sides and bottom of the pet flap, creating a tight seal. Most commercial pet flaps hang loosely or, at best, use one or two magnets on the edges.
  • Soft vinyl flaps need frequent replacement because they will wrinkle and crack in the sun and stiffen or break in cold conditions. Whereas, our pet flap lives up to its name as a durable, UV retardant flap that stays flexible at up to -40 degrees Fahrenheit.

4. Why Not Just Cut Into the Existing Glass Door or Window?

Glass doors and windows are actually made from any one of a number of kinds of glass.  Each one of these will need a different procedure to cut into or replace. Attempting to cut a hole in tempered or dual pane glass will shatter it. Other kinds of glass will crack badly, creating an unsightly and potentially dangerous hazard.

5. Are These Doors Easy to Install?

Our professional installers have the training and experience to get your new pet door set up in as little as 30 minutes.

6. How Do I Keep Other Pets from Getting in My Home?

Worried about the neighbors’ dogs or annoying wildlife getting in? This common concern is rarely an issue. Insects and very small animals are not strong enough to push through the door, and most larger ones won’t attempt to press against something that is tightly sealed to the frame and floor. There are no gaps around the edges of the Patio Pet Door thanks to our product’s high weather stripping, strong magnets along all free edges, and stainless steel strikes. However, it’s always a good precaution to keep food and water away from the pet door so hungry animals aren’t tempted to follow their noses inside.

7. Will I Have to Train My Pet to Use the Door?

Some pets pick up the trick of using this door and immediately start exercising their freedom to come and go, but others need a little help. If your companion needs training, try these tips:

  • Lift the flap yourself and show them the way in.
  • Sit on the opposite side of the door from your pet and call them, squeak their favorite chew toy, or offer a strong-smelling treat to lure then through.
  • If that doesn’t work, try propping the door open. When your dog or cat gets into the habit of accessing the yard through the Patio Pet Door, you can lower the flap again.

8. Are Pet Doors Energy Efficient?

New advancements in technology have made pet doors significantly more energy efficient to protect against extreme weather. Learn more about how energy efficient our doggy door for sliding glass door is.

I've been thinking about replacing my windows for awhile now but never quite got around to it. I was in a customers (I'm a handyman) home a few days back and noticed just how much nicer it felt in there since they had replaced their windows with the new energy efficient glass. A few days later a young man came to my door and gave me his sales pitch. Usually I just send them on their way, but somehow I liked his demeanor so I heard him out. Then after talking motorcycles for a bit, I agreed to meet with one of their sales reps. They called the next day and set up and appointment. At the appointed time Cassidy King came by and walked me through how their windows are manufactured and how she would take measurements of all of my windows and then give me a price that would be out the door so to speak. After that they would send out a fellow to take very accurate measurement and then they would build them custom fit to my home. When the build was complete (only a week or two as I recall) they set an installation appointment. Five guys showed up and went to work, positioning each window at the correct place it needed to be. Then they started removing the old windows and then installing the new. Having been in the trades for so many years, I watched them install that first window from start to finish. I was so relieved to see that they did it exactly as I would have done it myself. These five guys worked like a well oiled machine and each one knew exactly what his job was and they did it. It wasn't until they had cleaned everything up that they called it a day.At the end of the day all of the windows had been installed and the difference was felt immediately noticed. I no longer hear the cars that use my street and the F-35's flying overhead are now hardly noticeable. The next day a crew of two came back and trimmed everything out on the inside making everthing look great. I'm now on my third day of enjoying them and I notice that my A/C unit is cycling much less often then it was. Although I don't think I will need it, the lifetime warranty is a nice thing too! - 11/13/2025

Brad and Heliman installed our new windows and were fast and kind. Brad caught a measuring issue with our new sliding glass door… it had to be re-ordered and installed at a later date but our installers and the company handled it for us with no other issues. We are very happy with the customer service, installers and product. Thanks to Brad and Heliman for taking such good care of us. - 11/10/2025

Getting new windows was actually a fun experience, believe it or not. Jordan is not a typical pushy sales person. He provided information, options, and answered questions without pressure. He really cares. The installers were also kind, respectful, and hard working. We enjoyed having them there and visiting from time to time. Our house is a little unique with a pitches, slick, metal roof. Javier got up there in his bare feet and took care of business. He and Willy worked so well together. Willy called to let me know about times and check on things. Thank you everyone!!! - 11/10/2025
