I need to fit a cat flap in double glazed patio doors - there really isn't other place it can go...

I'm certainly not going to try DIY on double glazing - but has any one else done this? Or can recommend someone who can do it (without sucking their teeth, telling us the previous double glazing fitter was a cowboy & trying to sell us whole set of doors, rather than just one panel!)?

many thanks,

wmp

I'm don't think it's possible to fit a cat flap into double-glazed glass. It can be done in single-glazed but in double it's trickier and I expect would lead to the double-glazing failing and condensation problems. We had this debate last year as we had a fully double-glazed back door. In the end we admitted defeat and just bought a new door and got the door company to install the cat flap for us prior to fitting. I'm no expert though and someone else might be able to offer a solution but I'm sure when I researched it, I read that it wasn't possible.

I'm afraid it is not possible. Firstly the glass that is in the door should have been toughened for safety and any cutting needs to take place prior to toughening. Secondly, if you could cut a hole, the seal on the double glazed unit would be broken and you would lose all the benefit.

The only way to incorporate a cat flap into any door would be to have a plain, solid panel at the bottom. This is usually made of melamine faced chipboard and can easily be cut. Of course, this means having new, custom-made doors.

I think it depends on the design of the doorframe. If you have a PVC door with black rubber strips around the sealed double glazed units you can just replace the section with some painted board. There's a bit of a knack to it but after you've replaced the glass a couple of times you'll get the hang of it...

1/ remove thin black rubber strips on inside edges
2/ push glass from outside into gap created by removal of strips
3/ push the white pvc triangles into gap and unclick from surrounding
4/ remove glass outwards
5/ measure thickness of sealed unit as well as width and height
6/ cut board to size and reverse the instructions to re-fit

I used Walsh Glazing in Lordship Lane (020 8693 8254) to get new sealed units made up for my windows. I paid about £300 for six sealed units made up with laminated glass both sides (normally you'd only do laminated on the outside).

There's also a large glazier in South Norwood opposite the Ship pub in Penge Road. They have a lot of equipment behind the scenes and could probably do some specialist services like cutting glass then toughening it, if that's possible. I'm sure they could advise you further.

Many thanks for the replies - I've done a bit more research myself & come to the conclusion that either we get rid of the dishwasher (which we never use anyway), re-do the plumbing, box in the existing sink units & have a cat tunnel through the wall & cat steps down onto the patio, or I get a new patio door with the cat flap cut by the manufacturer - as it is all one large pane of glass, there's no crossbar for a panel at the bottom... A to B Glass was recommended somewhile ago on this forum, & the neighbours also suggested them, so they are coming to have a look at it this week.

Rehoming a cat is proving be rather expensive!

Another option would be to remove the door take it down to a double glazing shop, or where they actually make windows and doors and ask them to fit you a mullion / mid rail to the bottom of your existing door, insert a plastic panel which could then be cut to take the cat flap. You would obviously have to get this all done in the same day to avoid having no back door overnight.

You would then only need one replacement pane of glass, one new mullion and one foam packed plastic panel for the cat flap. I have had to do something similar to this in the past and I used a factory in Bensham Grove, Thornton Heath. The company I think was called Synseal or something like that, but it can be done.

I had the same dilemma a few years ago, double glazing, no possibility of a cat flap, so on a trial basis we just saw how it went. We got down to a routine whereas she was out all day in summer (where she did her toileting), or I'd let her out in the mornings in winter, and I'd let her in in the evening, it worked really well, you'd be surprised how easily they adapt.

There was only the one occasion pop-pop came running up the forty foot garden and crashed headlong into the closed sliding doors ouch ! :wacko:

I'm now living in a fourth floor flat since the last year, which I was worried about, but she is more than happy getting her 'outdoor fix' sitting on the balcony.

I did have a cat that was quite happy without a cat flap (mind you, she had brain damage & walking/breathing was a challenge, let alone using a catflap) - but we tried to rehome a Battersea cat & they, like several other rescue places, now won't allow you to re-home if you haven't got a cat flap. :( So it's a new patio door for me...

Hiya,

We recently had a set of french doors (in UPVC fully glazed) with a cat flap fitted by Bespoke Windows from East Dulwich. The only proviso that they needed to have was 10cm clearance from the sides of the glass to the fitted flap. So you need to be careful that any step to the door doesn't make it too high for kitty.

Overall Bespoke are a bit more expensive than some of the more dodgy salesmen and less expensive than Everest etc. etc. but they were the only ones that said they could do this rather than have a plastic panel.

The salesman that visited us actually talked through alternative openings etc for the windows and doors and suprisingly didn't blather on about the windows too much. The fitters were good guys, polite tea drinkers that got on with the work and tidyied up reasonably well afterwards too.

Fitted the windows make a terrific difference to our flat - it is so much less windy (couldn;t have described it as drafty really). Generally speaking I am happy to recommend Bespoke and as a local company I felt that it was worth the extra cash - quotes ranged from 1750 - 2700 and Bespoke came in in the middle of this. The lowest quote came from a strange man that gave me a card for a company that had no website or fixed landline, so you could almost discount that entirely..

Matt

For a very reasonable 34 you can get a gate that includes a cat flap from http://www.bettacare...s_Cat_Flap.html

A cat flap? In a gate?

How fat does your cat have to be to be rendered incapable of jumping that?

Whatever next? :rolleyes:

Well, I'm not endorsing the product, just letting people know in case it helps solve a problem. Perhaps you want the back door open in the summer, a toddler kept indoors but let the cat out. Or maybe you want to keep a toddler out of the kitchen but let the cat in to its food. I'm sure quite a few cats would take the easy option of a flap rather than a scramble... my neighbour's cat is so old he can only just about get onto a chair. It would suit him.
