Replacing upvc panel in door without usual plastic beading?

[offmypickle]

Hi all,

We've just moved in to our new place as tenants and I want to temporarily replace a upvc panel in the bottom of our french doors with one with a catflap in. I have done this before at my gf's last place, but there it was just a case of doing the usual - remove the rubber seals on the inside and popping out the beading on the outside, no problems.

With these doors it's different. Inside and out the panels have this hard black plasticky seal around the insides of the frame. It's unbroken at 3 of the corners. I had a try to pull it out at the other corner where the 2 ends meet, but no luck. It's almost like the seals/units are glued or sealed into the frame

Does this sound familiar to anyone? What are my chances to be able to do this? We've tried contacting some local double glazing firms but noone seems to want to know unless we bought the doors from them.

Thanks in advance for any help you can give.

Any chance of a few pictures. If the glass goes in then it must come out.

Yeah I'll put some pics up tonight when I'm back home, but I think I might have found the source of my confusion anyway.

I just talked to a friendly local tradesman (thanks 'Mr Mole'!) and I mentioned about the difference in the doors... he asked whether they are metal doors, and thinking about it, I think they are. Apparently these need to be taken off the hinges and taken apart to remove the units, in which case having no beading makes sense.

So looks like that might be the case here. Will confirm with pics later.

Cheers!

Cool, if your local tradesman is correct then it sounds like a wrap around gasket found on ali doors, if you can get some photos on i could confirm either way
