Patio doors are one of the most common places homeowners choose to install a cat flap. They provide easy outdoor access for pets while keeping the installation discreet.
However, patio doors often use double glazed glass panels, which means the installation must be handled correctly.
Why Patio Door Glass Cannot Be Cut
Many people assume a hole can simply be cut into the existing glass panel, but this is not possible with double glazing.
Double glazed units are factory sealed and contain two panes of glass with an insulating gap between them. Cutting into the glass would break the seal and damage the entire unit.
Instead, installers replace the original glass panel with a brand new double glazed unit manufactured with a hole for the cat flap.
The Installation Process
Installing a cat flap in patio door glass typically involves the following steps:
- Measuring the existing glass panel
- Ordering a bespoke sealed unit with a cat flap cut-out
- Manufacturing the replacement glass panel
- Removing the original glass safely
- Installing the new panel and cat flap
This ensures the patio door continues to function normally while allowing easy access for your pet.
Benefits of Installing a Cat Flap in Patio Doors
Patio doors are often the ideal location for cat flaps because they offer several advantages:
• Direct access to the garden
• Clean and discreet installation
• No damage to doors or walls
• Maintains the appearance of your home
When installed professionally, the new glass panel looks just like the original.
Choosing the Best Cat Flap for Patio Doors
Both manual and microchip cat flaps can be installed in patio door glass.
Microchip cat flaps are especially popular for patio doors because they provide extra security and prevent stray animals from entering your home.
Professional Installation Is Important
Accurate measurements are essential when replacing glass panels in patio doors. A properly manufactured sealed unit ensures the door remains weatherproof, insulated, and secure.
Professional installers also ensure the cat flap is positioned at the correct height for your pet, making it comfortable and easy to use.
