Pet Doors for Sliding Doors: Panel, Glass or Flyscreen Options
Choosing a pet door for a sliding door in Australia: compare a panel insert, a pet door fitted into the glass and a pet door mounted in a flyscreen.
Researched and edited by the PouchMe team Updated 19 October 2026 Every fact linked to its source
A sliding door gives you three routes: a panel insert that fits the door opening, a pet door fitted into the glass, or a pet door mounted in a flyscreen. The main decision is whether you want the pet door in the glass itself or an option that leaves the glass alone.[1],[2],[3]
Before any glass is cut or replaced, check the current glass rules for doors with the Australian Building Codes Board or your state building authority.[4]
Three ways to fit a pet door to a sliding door
| Route | Is the glass changed? | How permanent it is | What it suits |
|---|---|---|---|
| Panel insert | A retailer listing for a PetSafe sliding glass pet door says it needs no cutting or drilling.[1] | The same listing says the door adjusts to fit your existing sliding glass door.[1] | A slider where you want an option that needs no cutting or drilling.[1] |
| Fitted into the glass | Yes. The pet door goes into the glass itself. A Sydney installer says sliding doors and fixed glass panels can be fitted with pet doors.[2] | Toughened safety glass (glass cooled rapidly during manufacture so it is much stronger than ordinary glass) usually needs a custom replacement panel, according to a Sydney installer.[2],[5] | Sliders or fixed glass panels where you are happy to change the glass.[2] |
| Flyscreen mount | No. It goes into the mesh door, not the glass.[3] | A manufacturer says the door is secured through the mesh with screws.[3] | A slider that has a flyscreen mesh door. Pillar Products describes a slimline design to suit sliding doors.[3] |
Panel insert. One Australian retailer lists a PetSafe sliding glass pet door that adjusts to fit your existing sliding glass door, with no cutting or drilling. Bunnings lists the Hartman 300 x 180mm Medium Pet Door for Patio and Sliding Doors. It also lists the Hartman 385 x 270mm Large model, which is a two-piece aluminium unit with a stated height range of 1980 to 2100mm.[1],[6],[7]
- 1Open the sliding door and measure the track height at the lowest corner of the bottom track.[8],[9]
- 2Compare that figure with the height range stated for each model, and pick a model whose range includes it.[8]
- 3Be cautious if your measurement sits at the short end of a range, because the panel may be hard to squeeze into the track.[8]
Fitted into the glass. A Sydney installer says sliding doors and fixed glass panels (panes that do not slide) can be fitted with pet doors. Bunnings says its installation service covers single or double-glazed glass, screen and timber doors. One Australian retailer lists a glass pet door that fits glass and panels from 3mm to 10mm thick, so check your glass thickness against the stated range.[2],[6],[10]
Flyscreen mount. Pillar Products makes a flyscreen pet door that allows access through flyscreen mesh doors, and it is sold exclusively at Bunnings Warehouse. Its listed sizes are 202x254mm (Medium) and 305x406mm (Xlarge). For choosing a size for your pet, use the sizing advice in the hub guide.[3]

Sliding door questions
Can a pet door go in a flyscreen or security screen door on a slider?
Yes, for the screen door on a slider. Pillar Products makes a flyscreen pet door that allows access through flyscreen mesh doors, and describes its slimline design as suiting sliding doors. An Australian retailer describes the Petway security screen pet door as slim so the door can slide past, and says it can be fitted without taking the security screen door off.[3],[11],[12]
