Disruption installing Dry Lining?

Sysmod

So, I've just discovered this forum and will have to read a lot.

C Eastwood said in another post: "With insulation for Heat Loss reduction, you only need to insulate as much as is practicable." We're looking at a minimum retrofit for cosiness and money saving where possible. A visit by a one-stop-shop advisor indicated that we could do 10 PV panels, attic insulation top up of 100mm to 300 mm, wall insulation, and nine window replacements, for a 230m2 house for a total of about €24K inc VAT after SEAI grant. Details to be firmed up after paying a €615 non-refundable deposit for a BER assessment.

Most of the 1960s-70s house has cavity wall, that should be simple and relatively inexpensive to fill. Two rooms of the house are not cavity wall on one side, I don't know what it is, just panels I think with PVC cladding planks outside, about half the wall depth of the rest of the house. They recommended drylining but could only say "ask the insulator about that after we've started the project". I'd like to know more now. There are sideboards against that outer wall in one room and fitted kitchen cabinets in the other room. I understand that we need to achieve B2 to get an SEAI grant. Would it be enough to dryline the visible wall and hope that the cabinets provide some insulation? Otherwise all the fitted furniture would have to be ripped out and replaced and that sounds like a huge and expensive undertaking.

Separately, I'll ask about PV after I've read some more posts here.

Thank you in advance.

When I got drylining, all external walls had to be done to get the benefit - this included removing kitchen cabinets etc.

For roof insultation - do you mean attic insulation? if so, my recent upgrade was to 300mm - 100cm seems like an awful lot...

To be honest; I wouldn't be very confident with your supplier not being able to provide details and telling to ask after the project has started (i.e once you are locked in and have to proceed...)

Yes, I meant attic insulation, thanks for checking mairbu. My memory was nonsense, I've rechecked and edited to "attic insulation top up of 100mm to 300 mm"

Just for interest, roughly what was the cost to remove and refit kitchen cabinets? I could ask our local kitchen supplier, and hope they don't say "oh, we don't do that make any more, if there's damage we can't supply replacements..."

I replaced the existing kitchen units with new ones; so afraid I can't help with costs on refitting.
