Advice for cat flaps in doors

First of all, it’s worth addressing the question around fitting cat flaps within existing glass. Usually this is not possible and you’ll need new glass. Most doors come with safety glass. Once toughened, this glass type can’t be cut. Therefore you may find it easier to seek the services of a local glass replacement company and have new glass with a catflat replacing your existing pane.

By law, low-level glazing and doors must have safety glass. Therefore with toughened glass needing cutting to the right size before toughening, retrofitting is not possible.

For doors with PVCu panels, if you’re comfortable with the DIY route, you can cut these with the right tools and self-fit a suitable cat flat.

Pet Flaps in new doors

For new doors, we provide your glass ready with a cat flat provided. This method has proved the easiest over time as well as the fastest.

If you have a particular cat flap type and model in mind, it’s worth checking it’s suitability for use within 24mm or 28mm double glazed units. 28mm is the more common thickness of double glass in the latest generation doors.

There’s also a specialist glass adaptor we use making most types of pet flaps suitable, but this is always confirmed with your specific doors and glass types. It’s not usually possible to fit pet flaps within blinds built into the glass units.
