Purrfect Pet Doors - In Glass Pet Cat Dog Door
The actual pet door used in this application is the same door that would be used for a wood door installation, and it is made to fit a 1 3/4" door thickness. Glass won't be as thick as a door, and there are two ways to deal with this situation. Hale will include a "buildout" which is an aluminum frame that goes between the glass and the dog door. For example, if your glass is 1" thick, and the doggie door is made to fit 1 3/4" thickness, they would send a 3/4" thick aluminum frame with the pet door. The buildout frame can be installed on either side of the glass, but it will push one side of the dog door frame out 3/4" away from the glass. The other way to deal with this is to cut the pet door frame down to fit the thickness of the glass. Hale can cut the doggy door frame down to a minimum of 3/4". They do not charge for this service, but it does make it a final sale, so no returns. The advantage to using the buildout is that you get more space between the flaps, so should have better insulation. The advantage to cutting the pet door down is that it looks nicer.
