Most pet owners do not enjoy being disturbed in the middle of a spine-chilling scene on the television or in the middle of an interesting conversation with your neighbor so that they can take out their pets. The best option to avoid these interruptions is to purchase a pet door.

There is a huge variety of pet doors available in the market today, but if you are looking for a door that can be installed without cutting any holes in the door or walls, then a patio pet door is the answer. These patio doors are available in all sizes, so whether its a Great Dane who needs a walk or a kitty that needs to go out, its safe for all of them.

Patio doors have different models to choose from. There is the single-pane window, which can be fitted as a temporary or semi-permanent door on any glass door or screen door track. It is best suited for vinyl-clad sliding doors. There are also the thermo-panel patio doors, which provide the advantage of a dual-pane glass with the easy installation of a spring load and height adjustment feature of a quick panel. These sheathed or insulated dual-glass door panels are assembled using pre-fabricated glass units for efficiency. The height of these panels can be adjusted using the spring load assembly, which is totally tool free.

It is recommended that the patio pet door be as tall as the shoulder of the pet; a pet can duck, but it is better if he does not have to crouch his way through. Make sure he can pass through without much discomfort. These pet doors are also available in electronic versions, which operate with a magnetic key attached to the pets collar. Before an electronic patio door is installed, you must make sure that you have enough room to move about. A patio door panel takes off about twenty-one inches from the sliding glass door opening. It is always better to check an electronic patio pet door to see if it works properly before installation.
