Install a pet door through the glass in your sliding glass door or window, sidelight, or French Door

The "in glass" approach is a less obtrusive, cleaner, and more aesthetic approach to installing a pet door in a glass slider, window, door, or sidelight. Installing a pet door directly through glass means you can continue to use your existing locking mechanism (unlike patio panels, which require a wooden dowel or Charley bar). Both are great options, but the In the Glass choices are preferred by those who want to continue using their existing lock. Installing a pet door directly through glass is also an excellent choice if you prefer not to alter the aesthetics of your current glass door or window. The final look is clean and professional while allowing your dog to come and go and keeping your home insulated year-round. 

Helpful Tips

  1. Use a Glazier: The glass in your slider, window, or sidelight is going to be tempered and you can't cut that. The glazier will measure your glass, order a new piece--either single pane or dual--with a cut-out for the pet door and install it for you.  This is not a do-it-yourself job.
  2. If you Have a French Door with Separate Lites: You're in the wrong section. Remove one or more lites, cut down into the cross-piece if you must to make the step-over more manageable for your pet, and order a custom dimension pet door to fit that opening. There's only one--Hale Custom for Doors--and on that product page, you'll see an image of exactly what we're talking about here. (Make really sure those are separate lites and not one big sheet of glass with molding, making it look like separate lites).
  3. You can DIY and Here's How: Forget glass. You're going to use a piece of Lexan (generic name polycarbonate) cut to replace your glass and then cut a hole for a pet door in the polycarbonate. But note:
    1. The polycarbonate needs to be at least 3/16" thick or it's too bendy.
    2. Polycarbonate will scratch more easily than glass so this isn't good for a location, like a slider, that may receive some abuse.
    3. It's expensive as well so a window that isn't so large is a better choice than that big picture window.
    4. You can use a pet door designed to install in a door but if it's self-framing, and most are these days--be sure the thickness of your polycarbonate is in the adjustment range.
    5. If you want to go on the cheap, use plywood.
