How To Cat Flap in Double Glazed Glass Door 

Just done an outside catio for our house cat. It is big lean to against back of house with double glazed windows. Fed up of having window open. What a find, your tutorial is awesome. This will work with windows as well. Great instructions and video.

Doing an instructional video with one hand.Well done, mate.👍🏻💯 Now that I've seen it done, with some patience this looks more straight forward than I'd imagined.

Thanks, it hadn't occurred to me that I'd need a glass manufacturer to do the hole, but now seems completely obvious that's the only way to do it in double glazing! Good tutorial for removing the beads and putting back in.

Thank you very much for this, we're being quoted £200 to £300 plus but now i'm going to do it.

£96 including vat! I got 5 minutes in before I realised the fellow wasn't going to show me how to do it myself!

That’s the same brand as I just bought, to replace a broken unit. The glazier had cut the old cat flap mounting, but this wasn’t necessary as the double glazed door is wider than 5mm and had a sealed gasket put in. I Found it very difficult to line up the screws with the holes as they would move just as I lined it up and the new unit had a wider rubber strip. I tried three times it’s easier with the long screws and the leaflet says to use a collar under the screw head but then I can’t line them up I think it might be easier if two people fit it. So I used long screws and it moves a little but too scared to overtighten as it may strip out the plastic screw mounts. Good video.

Has anyone had any luck getting this done in the USA? Every single place I call - even custom glass companies - say that they don’t do insulated double glazed doors with premade holes for cat flaps.

Good video.. answered a lot of questions . Well done 👍👍👍

Great job! 👍 Thanks for sharing.☺

Many thanks! That was very useful.

Bravo! You’re very clever. I wish I could do the same, but I’m not so handy. Thanks for great instructional video :-)

How accurate did the dimensions of the new window glass have to be? It appeared to slide in pretty neatly. Unless it's a standard size they can work to.

Great video - very helpful....thank you

Hello great video thank you. may i ask who did this for you ? as i need this doing too many thanks

Cheers for this 👍 great job

Can anyone tell me how close the hole can be to the edge of the sealed unit?

Where did you purchased this? I am in England.

I work with Signature Home Improvements and if someone wants a cat flap we just install it free of charge on the day of installation

Brilliant! Thank you!

You are very brave

there is noise when the cat use the door? thanks

Cool Video! - have added it to my Fav's...as i'm planning to get a Cat!.....the quotes i've had from 'Cat-Flap' fitters are so expensive...and unbelievable! - :(

thank you beautiful man!

I thought this was going a whole different way as Iv been watching diy videos. May I ask roughly how much the pre cut glass panel cost. Iv just realised Iv got similar doors front snd back.

Hello! Can you help me please to find that guys who helped you with the new glass with hole for cat flap? Are you still in UK?

I was gonna pay a glazier to do the whole thing! I'm moving to Kent and need a cat flap in a double glazed unit. This video showed me how easy it is. Diamond Glass in Medway it is. Thanks

What is the make and model of the cat flap please?

what was the cat flap make and type please.

Nice job, well done 👏. Thanks for sharing, Just subbed. Take care, Steve.👍👍

The unit wasn't fitted correctly, the unit hasn't been set right with spacers it's lob sided.

Just make sure if you put a cat flap in a door unit it must be Toughened glass.

Thanks a lot 👍🐯

If you're going to pay for new glass why not have a go at cutting it yourself?
