Below, we’ll talk you through the process of selecting a dog door for vinyl sliding door or a dog door for sliding glass door, as well as other items:

Vinyl and Aluminum Sliding Doors

For many years, you could only get Aluminum frames for your patio door or sliding glass doors. However, Vinyl doors have become increasingly common and cheap to make.

Vinyl sliding doors are made from a plastic-based material, but are just as strong as Aluminum, and significantly lighter. Vinyl patio doors tend to be more energy-efficient, as the vinyl does not transfer heat as much as Aluminum. Vinyl sliding doors have thicker frames and wider tracks than Aluminum ones.

Aluminum is the more standard and common material used for sliding doors, particularly for older homes. Aluminum doors are often inexpensive and require little to no upkeep for many years. Aluminum sliders are thinner and have a smaller track width than their vinyl cousins.

However, if you already have a sliding door that you simply want to put an Endura Flap® panel into, you will need to select the correct material type to match your existing slider, and don’t have as much choice for which material panel you want.

 

Identifying Your Sliding Door Material

You want to make sure the material of your new dog door panel matches the material of your existing slider. If you put an Aluminum pet door panel into a vinyl track, it may work, but will not fit or seal as well as a vinyl panel. It is very important to correctly identify your sliding door material. 

The best way to know the material of your slider is to tap it with your fingers or a pen. The noise that you hear will tell you what material it’s made of. If it makes a panging noise like a frying pan, it is aluminum. If it makes a muted thunk, it is made of vinyl. 

Another way of guessing at the material is to measure the track and look at the wall thickness. Vinyl frames will be thicker and have a wider track. This is less accurate than the tapping method because different door brands will have different thicknesses and measurements. There is no such thing as a standard sliding glass door.
