How it Works

Glass100 supplies and installs dog doors into custom cut replacement panels of toughened safety glass. Once a job is confirmed a Glass100 Accredited Tradesperson attends site to conduct an exact measurement of the glass to be replaced as well as to confirm the required dog door model and location of the dog door in the glass. Back in the factory a replacement panel of glass is cut along with the hole for the dog door. This glass is then sent for toughening. Once the glass has returned from toughening an installation date is confirmed for the replacement glass and dog door.

Product Details

Our dog doors are specifically designed for installation into glass panels and are made from durable, high performance, plastics such as polycarbonate and makrolon. In addition to our standard range of dog doors, Glass 100 stocks a range of doors suitable for large dog breeds as well as an electronic, microchip activated, selective entry pet door suitable for small and miniature dogs.

​Frequently Asked Questions

I already have toughened glass, why don’t you just cut a hole in it for me?

If you attempt to cut glass once it has been subject to the toughening process, the glass will shatter. (In industry talk, the ultimate limit state, ULS, is exceeded). Thus, the glass needs to be cut to the right size and have the hole cut into it prior to instigating the toughening process.

How do I know which pet door is the right size?

The simplest way to test which door is the right size for your pet is to template the dimensions of the cat flap or the dog door (available here) onto a cardboard box, then cut a hole in the cardboard box the same size as the pet flap. Once the hole the same size as the pet flap has been created, gently place your pet into the cardboard box and see if it can fit through the opening to exit the box.

When will my new dog door be ready?

Standard working time from measure to installation is 4 to 8 working days.*Subject to seasonal and supply chain variations.

What warranty does Glass100 provide on Dog Doors?
Glass100 pet doors that are installed into stationary panes of glass, receive a 12 month replacement warranty against faulty workmanship. 

Warranty excludes inappropriate use and malicious damage.
Can my cat use a large dog door?
Well the answer to this question depends on the cat and the height that the large door is placed from the ground. If the cat is cunning and strong then it is possible for the cat to work out that if it pushes the corner of the pet door flap hard enough it can make the flap open just like Ziggy the Cat here. Other ways that cats use large dog doors is to follow a dog through whilst the flap is still moving. We have also been told about cats that have actually trained the household dogs to open the pet door for them. But not all cats are this determined or dominant.
Do you sell microchip activated dog doors for large dogs?
Not currently.

Although Glass100 has trialed many different microchip activated dog doors for large dogs we are yet to find a design that is both functional and robust enough for ongoing use by large dogs in our hot Australian climate. 
Do I need to pay a deposit on my dog door?

For your pet door to be put into production a deposit of $100 is required with the balance being due on installation.
