Most Commonly Used Pet Doors for Thinner Applications
Installing a pet door in a storm door is just as easy as installing a door mount
model pet door in a regular door. The main consideration is the
thickness of the door.
Storm doors basically come in two different types, thin metal-bottomed type and the thicker insulated versions. Some storm doors might have a panel
design on the lower portion as well. You can install a pet door in
panel-design doors, but may want to caulk or shim around the frame of
the pet door for weather sealing.
Special Note:Be aware that ordering storm doors with pet doors
already installed from online retailers often are expensive to return if they do not fit and most always have a hefty restocking charge.
