All three brands are considered the highest quality pet doors on the market, and that is the reason we carry all three. In terms of the differences they are the following:
1) PlexiDor pet doors are going to be the highest quality in terms of materials. They use a very strong shatterproof and insulated acrylic panels. The doors open similar to swinging saloon doors, whereas most other pet doors are tradition flaps. PlexiDor is the best for any dog who loves to chew
. They also offer a 10 year warranty. While insulation is great, a "double" flap version of either Patio Pacific or Hale may be better at insulation.
2) Hale Pet doors is the brand with the most options to customize in terms of size, wall depth, training flap, etc. In general, smaller dogs have an easier time opening Hale doors than the other two brands. Insulation is about on par with Patio Pacific when purchasing a "double" flap, which is recommended for winters in NJ. Hale makes a fantastic door, and is a fantastic company to work with. Warranty is 5 years.
3) Patio Pacific Endura Flap wall mounted pet doors are definitely our most popular selling doors. As mentioned previously, the insulation with a "double" flap is on par with a Hale door. There is less customization overall, but the installation is probably the easiest of the three brands of doors. They also have a 10 year warranty.
