How much window reveal can be insulated?

[frutbunn]

It is a solid wall, and the main goal is to stop condensation mould.

Then ignore bennymultiboard you need insulation, his solution will only give a very negligible amount amount of insulation, the BCO won't be happy either with that "solution".

Sorry, which solution bco won't be happy with? Not that they will be looking at it.

I'm happy to put in as much as i can fit, unless there is a reason not to go right up to the window beading.

Bennyultiboards stupid idea to use 2 layers of plasterboard, total waste of time. Try and get as much insulation as you can.

One issue with going up to the beading is that if the glazing unit blows, and needs replacing, it could be tricky.

Worth sourcing some 10 or 25mm board if you can.

This is 25mm board, no thinner board in b&q. They did have some cork boards, will that be enough to stop condensation mould?

so his op shows 25mm celotex and a 12.5 mm board . that’s already too thick in relation to the glazing beads. and doesn’t even include any bonding materials or plaster, so he’s looking at ‘insulating and finishing a reveal with a combined max thickness of around 30mm including insulation , board, adhesive and plaster if he wishes.
lets hear it genii!

British gypsum did a pre insulated board specifically for this, they demonstrated it last time I was their factory in Cumbria. I can't remember the name of it. I'll have a look when I get a chance

Bennymultifinish ever heard of Dunning Kruger?

Fascinating. apparently we all suffer from it to a degree.

i’d direct you to my website, but it’d be wasted on you.
go back to your desk boy.

they’re called thermaline scholar. and the thinnest is eeeeeeerrrm 37 or 38mm iirc.

Maybe this with 9.5mm plasterboard?

oooh wait til the bco finds out about this

It'll be a long wait.

Well at least it stands a chance of actually achieving something, unlike your other nonsensical attempt at a "solution"!
