Through the Glass:

    I need to install a pet door but the new house has only two exterior doors, both single heavy wood doors with double pane glass panels.

    Is there any solution to this? Your help is greatly appreciated.

    The door is 35 1/4″ wide by 95″ tall. The double pane glass panel in the door is 21″ x 78 1/2″

    Can a thermal double pane glass panel be cut and still be useful/sealed? Or, do I purchase a new insert to the door that perhaps is a dog door on the bottom with glass above it?
