What you’re looking for in a retractable screen door depends on your needs. If you have pets in the house (ones that can scratch, chew, and are fairly powerful), then a pet resistant screen is a good choice for you. These can be up to ten times as enduring and tear resistant than normal retractable screen doors. These doors with pet resistant screens will ensure that your dog or cat will not be able to punch a hole through the screen, if they find an interesting animal pattering around outside. Another choice is a heavy-duty screen, which is about five times heavier in weight than the standard bug resistant screen door. This will not only ensure that your pets do not break through the screen by running at them, but it will be impervious to chewing, which can slowly wear away some pet resistant screens. When you’re shopping around for a retractable screen door, just ask questions and make sure you’re getting a door that fits your needs. A last option that may be less desirable to most people is a pet guard, that covers the bottom half or third of your door. It is usually made out of aluminum and will prevent tears from pets jumping up on the screen door.
