UPVC window beading very close to reveal

[dave_104]

Hi
I'm fitting some insulation and new PB to the window reveals but am concerned that it's going to finish far too close to the window beadings which could make a broken pane replacement very difficult. I've currently put 25mm insulation up there dry-fit to test and by the time 12.5mm PB goes on and it's skimmed then we're right on the edge.
Options I can think of -
a. use 15mm insulation instead and 9mm PB (I don't like this).
b. find the window manufacturer and buy some spare beading so I can cut the old beading apart to weaken it to pull it out.
c. find a really good removal tool which is claw shaped and strong enough to pull the beading away without levering into or damaging the reveal - does anyone know of anything like that and could recommend something??

Thanks,
Dave

Insulating a window reveal

Hi all, I'm internally insulating a North facing wall in my house. I've removed all the existing plaster and now I've measured up I think I'm going to have an issue with the reveals. My original plan was 25mm celotex, 9.5mm plaster board and allowing for 3mm skim that comes to 37.5mm...

Thank you very much for that
I did look before posting and the search results came up with nothing.
Great tip on your post about thinning down the insulation too - I've just ended up buying some 15mm stuff because I couldn't think of how to cut the 25mm boards down neatly.
