FAQs
More on our pet doors in glass
Here are some of the most commonly asked questions to help you decide the right door for your pet.
We offer a range of glass-compliant pet doors from renowned brands that are made from tough polycarbonate plastic, which is ideal for installation into glass. To ensure a safe and long-lasting installation, each of our pet door types has a minimum panel requirement.
To assist with your enquiry, please have measurements of the glass panel (and photos as well).
We have a tried and tested range of pet doors available for installation. There are three sizes available – small, medium and large, and suit both cats and dogs (of up to a Labrador size). See our pet door range above
Remember if you have a puppy, you will need to ensure the door you select is big enough to accommodate your pet when it is fully grown.
Our consultants can help you choose the best door for your pet and discuss what you need to consider when thinking of where to place the pet door as well.
We recommend you choose a door that will suit your full-grown pet. Refer to the weight-range guide (for each pet door in our range) as an indicator of the most appropriate door size to choose. View our range of pet doors above.
If you are unsure, our expert glazing consultants can help you choose a suitable pet door – if you can confirm your dog’s breed, weight, chest width & shoulder height.
The location of your pet door should allow your pet easy or level access to a garden or safe space away from busy roads. At O’Brien Glass, we only install pet doors in glass, most suited to low-level glazed panels in a door, sidelight or a lowlight panel located on the perimeter of a room.
We also install pet doors on sliding glass doors, as long as appropriate consideration is given to allow for the passing gap when the doors are opened.
We suggest that your pet door should not be easily visible from the street as this could be an access point for burglars.
When our glaziers visit your premises for the initial visit, they’ll work with you to recommend the best location for your pet door that’s safe for your pet and your family.
No. It’s important to first determine a few important details before deciding on where the best place is to install your pet door.
Things to consider include:
– the size of the pet door
– the minimum glass panel size for the chosen pet door and
– the type of window or door that you’re thinking of installing the pet door into. For example, some pet doors cannot be installed in sliding doors.
Our O’Brien Glass solutions team will be able to assist in determining if where you’re thinking of putting the pet door will work. Be prepared to provide measurements of the glass panels (and photos) to help with your enquiry. If you are unsure where to put the pet door, our O'Brien Glass glazier can help when they visit your premises for the initial visit. We’ll work with you to recommend the best location for your pet door that’s safe for your pet and your family.
At O’Brien Glass, we only install pet doors in glass as this is our speciality. Our chosen range of pet doors are glass compliant, so you can be sure that your chosen door solution will be safely and securely installed, keeping your family and pet safe.
For safety and durability purposes, we only use toughened glass. This custom-made glass has to be precisely cut to size to suit your requirements, including the hole where the pet door will be installed. Toughened glass is more resilient to the constant flexing and knocking it will endure as your pet goes in and out of the door.
